Evaluation of Data Catalog Software for Hanford Site Environmental Datasets

Environmental information and data underpin achievement of the U.S. Department of Energy (DOE) Office of Environmental Management (EM) mission at the Hanford Site. The Hanford Environmental Data Management (HEDM) Program is the DOE Richland Operations Office (RL) approach to develop and implement a formal program for managing environmental data and the associated records, materials, and systems at the Hanford Site. The current project, contract, organization, and contractor-specific efforts at managing environmental data sets are insufficient to provide orderly, long-term, site-wide access. A vital element to be created within the HEDM program plan is a catalog of data sources, called the Hanford Environmental Information and Data Index (HEIDI), that will enable long-term access and retrievability for the multiple independent sources of data that might otherwise be difficult to discover. This report compares leading open source and commercial data catalog platforms using criteria to assess the functionality needed to develop the HEIDI catalog of Hanford data sources that connects and exchanges data with established Hanford Local Area Network (HLAN) enterprise information technology systems. Proprietary platforms evaluated included ArcGIS Enterprise Sites, Junar, OpenDataSoft, and Socrata, and non-proprietary platforms included Energy Data eXchange (EDX), Comprehensive Knowledge Archive Network (CKAN), and DKAN (a Drupal-based open data portal based on CKAN). Capabilities supporting data discoverability, retrieval, and archival, as well as metadata standard requirements and integration into the HLAN were rated as either failing to meet requirements (F), meeting requirements (M), or exceeding requirements by delivering additional desired features (E). The lowest rating for any capability area was assigned as the overall rating for the platform. These findings enable DOE-RL and the contractors implementing the HEDM plan to focus on candidate tools likely to meet the requirements for implementing HEIDI. All of the platforms receiving an overall rating of ‘F’ were unable to be deployed on Hanford infrastructure or within dedicated cloud resources. A propriety software-as-a-service (SaaS) model of delivering a data catalog (e.g., found in software such as Junar and OpenDataSoft) favors consistency across customers at the expense of customization and configurable roles that are needed for Hanford work. Hosting data on a shared commercial platform places limits on dataset size (maximum of 240 Mb for OpenDataSoft), a significant limitation for HEIDI implementation. EDX, a government data catalog based on CKAN, received the ‘F’ rating due to an inability to incorporate authentication from HLAN into the system. Among platforms rated ‘M’ or ‘E’, only the Socrata platform had a SaaS delivery model. In contrast to other SaaS platforms, Socrata provided custom roles and gateways that allow local datasets to be incorporated into an online catalog. Socrata also complies with the Federal Risk and Authorization Management Program, a significant benefit for cloud-based management of Hanford data. The other platforms rated ‘M’ or ‘E’, ArcGIS Enterprise Sites, CKAN, and DKAN, provide fully self-hosted options, allowing for greater control and flexibility with the HEIDI catalog. These widely used tools have supportive communities of practice, extensive customization options, and demonstrated deployments that provide evidence that they can meet requirements, often deliver additional desired features, and work well with federal government systems. Completely customized alternatives built on a collection of applications were not evaluated because achieving similar performance to CKAN or DKAN requires substantial resources, especially in the absence of the active communities that have grown to support these tools. ArcGIS Enterprise Sites, Socrata, CKAN, and DKAN were evaluated as strong candidates for successful implementation with HEIDI.

Approaches for Successful Implementation of DOE-STD-3009-2014 - 18585

The U.S. Department of Energy (DOE) released a new version of the standard for the Preparation of Non-reactor Nuclear Facility Documented Safety Analysis, DOE-STD-3009-2014. Although this revised standard only specifically applies to new facilities, major modifications to existing facilities, and existing facilities with mitigated offsite consequences greater than 25 rem, other existing DOE nuclear facilities are beginning to implement the new requirements in this revised standard as well. The most obvious change is the consolidation of the eleven Safety Management Program (SMP) chapters into a single chapter. However, development of a compliant safety analysis is more than an effort in shuffling these sections. Examples of the substantive changes include: a more rigorous approach to defense-in-depth; a more comprehensive process for functionally classifying safety-supporting structures, systems and components; explicit direction for evaluating chemical hazards; and additional quantitative analysis for co-located workers. For any facility, the publication of an approved Documented Safety Analysis (DSA) and associated Technical Safety Requirements (TSRs) is a significant milestone. However, implementation of the DSA/TSR is often the greater challenge. Ensuring that the implementing assumptions, analysis inputs, and operational limitations are realistic is critical to this success. This should be addressed in the safety basis strategy document. In addition, DSA implementation must occur using a logical and planned approach. The approach should address the following: - Procedure preparation, review and verification; - Operator, mechanic, technician, and support staff training; - Management assessments to evaluate SMP effectiveness; and - Independent assessments to confirm effective DSA implementation. This project approach to managing DSA/TSR development and implementation has been demonstrated as successful at multiple DOE sites. Lessons learned associated with all of these topics will be discussed in the context of the new DOE-STD-3009-2014 requirements. The discussed lessons are taken from the multiple DOE sites and facilities. The presentation describes implemented approaches for successful incorporation of these lessons. While the context for the presentation is DOE-STD-3009-2014, the need to properly manage safety basis development and implementation applies to all nuclear facilities. Thus the lessons and implementation strategies should appeal to a general audience interested in safety basis development. (authors)

Desktop Audits: Overview, Case Studies, Guidance

The Energy Independence and Security Act (EISA) of 2007 requires that federal agencies audit 25% of their 3.1 billion square feet of covered facilities each year. Several newer, advanced options such as monitoring-based commissioning, fault detection and diagnostics, and energy management systems can help support data collection and analysis to be used for EISA compliance. The Federal Energy Management Program's (FEMP’s) Audit Decision Tree, Audit Definitions, and FEMP Guidance can be used by Agencies to determine the best approaches to evaluate their facilities. FEMP continues to develop additional resources to support agencies in meeting EISA compliance. This presentation gives an overview of desktop audits, including case studies and guidance.

Fluor Idaho's Technical and Programmatic Approach That Resolved the Problems with the Integrated Waste Treatment Unit - 19290

The Integrated Waste Treatment Unit (IWTU) is a facility designed to treat approximately 900,000 gallons of radioactive liquid waste, referred to as Sodium Bearing Waste (SBW). IWTU is a Fluidized Bed Steam Reforming process that will be used to treat the SBW to produce a granular sodium carbonate and sodium aluminate product. The product is planned to be managed as remote handled transuranic waste. Construction of the IWTU was completed in 2011 and Critical Decision 4 was achieved in 2012 with the expectation that the treatment of the SBW would be completed in 2012. However, process instabilities and equipment problems prevented the safe and reliable operation of the facility. All of the nonradiological tests of the IWTU had to be stopped prematurely because each time the IWTU was operated, the process would become unstable within a few days of initiating the operation. The instabilities were associated with the primary fluidized bed reaction vessel, the Denitration Mineralization Reformer (DMR). The instabilities included difficulties maintaining fluidization conditions and scale formation within the DMR. Design inadequacies and equipment reliability problems in other parts of the facility also hampered the testing the IWTU. The U.S. Department of Energy (DOE) awarded the Idaho Clean-up contract to Fluor Idaho (Fluor) in 2016. To resolve the issues with the IWTU, Fluor assembled a dedicated team to develop the technical and programmatic strategy to resolve the issues with the IWTU and get it operational. Fluor's approach has successfully resolved the primary issues with the IWTU. As a result of modifications of equipment and operating strategies implemented by Fluor, the core part of the IWTU process now works reliably when processing simulated Sodium Bearing Waste over a wide range of operating conditions. This paper describes Fluor's approach and summarize key steps in the process to resolve the issues with the IWTU. Fluor has used strong fundamentals including a first principles approach and unique program management techniques to solve the technical problems with the IWTU. The successful approach has provided renewed confidence in the IWTU process enabling the troubled project to move forward. Important factors in the success of the project include using a dedicated project team separate from the IWTU line organization, a Technical Review Group, the Chemistry Team and a diverse set of supporting contractors and National Laboratories. Fluor typically used multiple means to validate solutions before testing them in the IWTU. Fluor's successful full-scale demonstration runs of the IWTU confirm the process will reliably produce a compliant, treated waste product over a wide range of operating conditions.

Supplement to M&V Guidelines: Measurement and Verification for Performance-Based Contracts Version 4.0

Measurement and verification (M&V) are key to determining and confirming the continued operation of, and savings associated with, performance-based contracts. The Federal Energy Management Program (FEMP) updates these guidelines to reflect the evolution of M&V to incorporate industry best practices and ensure that savings from these performance-based projects are properly planned, communicated, and realized. FEMP released M&V Guidelines: Measurement and Verification for Federal Energy Projects Version 3.0 in 2008. This document was developed with input from industry-government working groups, previous M&V guideline authors, and national laboratory subject matter experts. The document provided the methods and guidelines, with a focus on federal energy savings performance contracts (ESPCs). When FEMP released M&V Guidelines: Measurement and Verification for Performance-Based Contracts Version 4.0 in 2015, FEMP expanded the intended audience to include anyone (energy managers, procurement officers, and contractors) involved in implementing performance-based contracts. The streamlined M&V Guidelines Version 4.0 provided the procedures and guidelines needed to quantify savings resulting from installing energy-efficient equipment, water conservation, improved operation and maintenance (O&M), renewable energy, and cogeneration projects with a performance-based contract; however, it removed some of the associated details on topics such as developing regression models and sampling plans. The details and information provided in M&V Guidelines v. 3.0 are still pertinent to M&V for performance-based contracts. The objective is to keep FEMP M&V version 4.0 condensed, providing the reference document for specifying M&V methods and procedures and a resource for developing project-specific M&V plans; this supplement provides additional details. The content of this supplement has been updated to include pertinent revisions between M&V version 3.0 and M&V version 4.0 by providing details and updating the content to ensure relevancy.

Lessons Learned From the Cesium Pond Soil Shipping Campaign at Whiteshell Laboratories - 18206

Whiteshell Laboratories (WL), located in Manitoba, Canada is the first major decommissioning project of a nuclear research establishment in Canada. With the focus now active remediation to return the site to green state, the majority of legacy radioactive waste and waste generated from decommissioning and demolition of nuclear facilities must be transported off site to Chalk River Laboratories (CRL), located in Ontario, Canada. No large radioactive waste shipment campaigns have been undertaken by WL until now. A newly established Waste Management Program specifically designed to support the WL Closure Project has executed its first major shipping campaign of radioactive material, making approximately one hundred shipments and reducing WL's total volume of low-level radioactive waste to transport by seven percent. The shipped waste was approximately 1800 m{sup 3} (2600 metric tons) of known Cs-137 contaminated soil material generated from the excavation of an Experimental Cesium Pond Project designed to study the distribution of dose received by organisms living at the mud-water interface from Cs-137 contamination. This paper outlines the cost benefit analysis undertaken to determine the most cost effective method for transporting the radioactively contaminated soil to CRL, storage challenges experienced by both WL and CRL, the selection of the most appropriate waste package, training of shippers, and the continual optimization of increasing the number of generated waste packages and the number of waste packages shipped and accepted at CRL.

Flammable Gas Generation and Control at the Idaho Completion Project Legacy Combustible Gas Generation - 20191

On April 11, 2018, four drums containing transuranic waste at the Idaho National Laboratory underwent over-pressurization, ejecting their lids and spreading radiological waste within a facility. An investigation has found that waste in the drums generated methane gas, which contributed to the event. Subsequent to the investigation, the potential for drums to have methane and other flammable analytes whose concentrations could approach or exceed the lower flammability limit (LFL) and the adequacy of the controls to prevent or mitigate a possible deflagration was evaluated. An extensive review of the historical records was performed to determine how many drums exceed the LFL. The historical record identified a small quantity of drums that exceeded the LFL for xylene, hydrogen, and methane. The primary codified applicable code or standard for handling drums is 29 CFR 1910.120 (j) 'Handling Drums and Containers.' It is used throughout the commercial and government sector. This code is integrated throughout the Fluor Idaho safety management programs and procedures to control the Standard Industrial Hazards (SIHs) associated with drum and container handling. Example requirements include: - Drums and containers are inspected, and their integrity assured prior to being moved. - Site operations are organized to minimize the amount of drum or container movement. - When there is a reasonable possibility of flammable atmospheres being present, material handling equipment and hand tools are of the type to prevent sources of ignition. Drums and containers under pressure, as evidenced by bulging or swelling, are not moved until the cause for excess pressure is determined and appropriate containment procedures have been implemented to protect employees from explosive relief of the drum. Drums which exceed the WIPP FGA limit have NCRs associated with them. Once a drum fails flammable gas sampling, an NCR is initiated. The NCR drives placement into NCR dense pack rows. A standing order drives placement of the FGA failures to a single planer segregation location. These drums are not allowed for further processing or shipment until the NCR has been cleared. Once in the single planer rows, follow-up FGA testing is performed by CCP. The NCR is dispositioned by follow-up sampling occurring after adequate time has been provided for the gas to diffuse through the filter assembly, or, in some cases, the drums are repackaged into additional drums to reduce the source term. To date, the ICP project has performed approximately 1.5 million drums moves without a deflagration event due to combustible gas generation. Flammable gas generation in a transuranic waste drum is not unique to the ICP but is common across the DOE complex. Based on the experience at Idaho, application of industry standards is sufficient to control the risk of drum deflagration due to drum movements. (authors)

A Photovoltaic System Payback Calculator

The Roof Asset Management Program (RAMP) is a DOE NNSA initiative to manage roof repairs and replacement at NNSA facilities. In some cases, installation of a photovoltaic system on new roofs may be possible and desired for financial reasons and to meet federal renewable energy goals. One method to quantify the financial benefits of PV systems is the payback period, or the length of time required for a PV system to generate energy value equivalent to the system's cost. Sandia Laboratories created a simple spreadsheet-based solar energy valuation tool for use by RAMP personnel to quickly evaluate the estimated payback period of prospective or installed photovoltaic systems.

Needs for integrated risk assessment to support optimal environmental management decisions - 15455

Cleaning up legacy waste from 50 years of nuclear weapons production and energy research still remains a challenge for the U.S. Department of Energy (DOE). The DOE environmental management program is currently forecasted to run through at least late 2060's with an estimated liability of $204 billion. Risks to human health of workers and the public, the ecological system, and nuclear safety of cleanup activities continue to drive the cost of DOE's cleanup programs. Currently, these risks are generally assessed and managed independently of each other. Except for DOE self-regulated on-site disposal activities of low-level radioactive waste, risks to human health and the environment are generally under the purview of U.S. Environmental Protection Agency and State regulatory agencies, while nuclear safety risks are regulated by DOE with oversight from the U.S. Nuclear Regulatory Commission and the Defense Nuclear Facilities Safety Board where appropriate. When managing health and environmental risks, the individual regulatory authorities often use an area-by-area (or unit-by-unit), contaminant-by-contaminant (chemical-by-chemical or radionuclide-by-radionuclide) approach, focusing on a single medium (soil, water, or air), a single source (e.g., a burial ground or a processing facility), and a single receptor (e.g, a groundwater well or a creek). This level of segregation in risk evaluations by risk category, geographical location, and operational unit, as well as the corresponding separation of regulatory authorities poses a significant challenge to reaching an optimal decision in prioritizing and managing cleanup activities. This management challenge adds another layer of complexity to large-scale cleanup effort at complex sites such as the Hanford site in eastern Washington. Therefore, to support a scientifically sound, operationally robust decision making process, there is a need for an integrated, holistic approach to risk assessment that addresses the combined effects of all major contributing factors. Previous studies have pointed out the need for integrated risk assessments that address multi-contaminant, multimedia, multi-pathway exposures, for the purposes of evaluating risks to human health and the environment. We believe that a comprehensive risk assessment should also take into nuclear safety risks that are associated with handling of nuclear material either retrieved from burial sites or to be decommissioned from nuclear facilities. Recent efforts, such as the Consortium for Risk Evaluation with Stakeholder Participation (CRESP)-led Hanford site-wide independent risk review that will categorize all types of risks at the Hanford site and the DOE complex-wide risk review mandated by the Fiscal Year 2014 Consolidated Appropriations Act ('Omnibus bill'), are beginning to more comprehensively address this need. This paper provides a categorization of various types of risks present at typical DOE sites, reviews the current risk assessment and management practices, and discusses the needs for integrating nuclear safety into performance and risk assessments for optimal cleanup decisions.
