Potential Energy Cost Savings from Increased Commercial Energy Code Compliance

An important question for commercial energy code compliance is: “How much energy cost savings can better compliance achieve?” This question is in sharp contrast to prior efforts that used a checklist of code requirements, each of which was graded pass or fail. Percent compliance for any given building was simply the percent of individual requirements that passed. A field investigation method is being developed that goes beyond the binary approach to determine how much energy cost savings is not realized. Prototype building simulations were used to estimate the energy cost impact of varying levels of non-compliance for newly constructed office buildings in climate zone 4C. Field data collected from actual buildings on specific conditions relative to code requirements was then applied to the simulation results to find the potential lost energy savings for a single building or for a sample of buildings. This new methodology was tested on nine office buildings in climate zone 4C. The amount of additional energy cost savings they could have achieved had they complied fully with the 2012 International Energy Conservation Code is determined. This paper will present the results of the test, lessons learned, describe follow-on research that is needed to verify that the methodology is both accurate and practical, and discuss the benefits that might accrue if the method were widely adopted.

A Comprehensive Solution for Managing TRU and LLW From Generation to Final Disposition - 13205

A LANL multi-disciplinary team faced the challenge of building and delivering a waste information system capable of managing radioactive, hazardous, and industrial waste from cradle to grave. The result is the Waste Compliance and Tracking System (WCATS) a flexible, adaptive system that has allowed LANL to consolidate its legacy applications into one system, and leverage the advantages of managing all waste types within a single scalable enterprise application. Key functionality required for robust waste operations, include: waste characterization, waste identification, transportation, inventory management, waste processing, and disposal. In order to maintain data quality, field operations such as waste identification, surveillance checklists, wall-to-wall inventory assessments, waste transfers, shipment pickup and receipt, and simple consolidation operations are captured by the operator or technician using mobile computers. Work flow is managed via end-user defined work paths, to ensure that unit operations are performed in the correct order. Regulatory compliance reports and algorithms are provided to support typical U.S. EPA, DOT, NRC, and DOE requirements, including the EPA hazardous waste manifest, NRC LLW manifest, DOE nuclear material at risk, RCRA TSDF inventory rules, and so forth. The WCATS application has allowed LANL to migrate and consolidate its disparate legacy applications. The design and implementation is generalized so that facility owners can customize the user interface, setup facilities and unit operations (i.e., treatment, storage, disposal, characterization, and administrative), define inventory compliance rules, and establish custom work flow requirements.

The container database? life-cycle management of container inventories at the Hanford site - 15131

Since 2011 the Department of Energy (DOE) Richland Operations Office (DOE-RL) and their contractor CH2M HILL Plateau Remediation Company (CH2M HILL) have worked together to develop a database that provides life-cycle management and control of all CH2M HILL-managed Department of Transportation (DOT) Type A and Industrial Packaging (IP) container assets at the Hanford Site. This powerful tool provides CH2M HILL with the capability to centrally manage container procurement specifications; maintenance requirements; certificates of conformance; certification and test reports; as-built drawings; and information on container status, location, and ownership; and any special characteristics of container assets. The database was originally developed to provide ready access to Type A and IP container supplier and manufacturer Certificates of Conformance (CoCs) and related certification documentation to support onsite shipments in compliance with the Hanford Site Wide Transportation Safety Document (TSD), DOE/RL-2001-0036, as well as regulatory or other requirements. The information is accessed through active links to these documents within the database itself. The database has grown to include links to external supplementary information to support onsite shipments, such as links to authorized tie downs for each package type, approved packaging and transportation commodities, and approved shipping authorizations, and packaging management procedures and checklists. The database is a living databank that is easily tailored to meet user- and site-specific needs as they are identified. It is currently being expanded to include the inventories of all Hanford contractors, as well as other packaging assets, such as specialty drums and packaging commodities. Each upgrade brings efficiencies and cost savings, not only in container inventory management, but also in the areas of work control, waste packaging, waste transportation, and regulatory compliance.

Development and Maintenance of a Comprehensive Radioactive Waste Management Basis - 16349

In accordance with DOE Order 435.1, 'Radioactive Waste Management', radioactive facilities and activities must have a documented basis of operation consisting of procedures, and physical and administrative controls that ensure protection of workers, the public, and the environment. To fulfill this requirement, Department of Energy (DOE) facilities are required to have an approved Radioactive Waste Management Basis (RWMB) which provides assurance that controls are developed, documented, and implemented for management of radioactive waste. The required elements of the RWMB vary with the type of waste management operation or facility and the types of hazards associated with the facility. Therefore, a graded approach is used per DOE guidance. The Idaho National Laboratory Waste Management Program (WMP) has developed and implemented a thorough RWMB for each of its five operational areas in addition to facility specific DOE Order 435.1 compliance tables which served as a tool for developing each RWMB. With approximately 40 facilities generating and/or managing radioactive waste, the WMP has encountered several challenges in keeping RWMBs current and accurate, in addition to ensuring facilities are continually maintaining compliance in evolving conditions in support of programs and projects in a continuously expanding research environment. Prior to initial radioactive waste generation, nuclear facility management must demonstrate compliance via the facility safety basis and approved laboratory-wide and facility specific documents which are then incorporated into the RWMB and subsequently approved by the DOE-Idaho Operations field office designated point of contact. The WMP has incorporated several areas of improvement to its RWMB management strategy to help facilities maintain compliance in new and changing conditions. Improvements included providing ad hoc facility management training for new facility managers, adding a reviewer from the WMP during the environmental checklist process, and performing annual RWMB reviews which involve not only facility management, but also Waste Generator Services support personnel, and other support organizations, as applicable.

Fortifying Environmental Compliance Strategies at Hanford - 19541

At the Hanford Site, located near Richland, Washington, the Department of Energy is cleaning up legacy radioactive and mixed-waste generated from the Manhattan Project in the 1940's. A major component of cleaning up the waste is maintaining compliance with federal and state environmental regulations. Environmental compliance is also determined through permits, agreements, and consent orders issued by regulating agencies such as the Washington State Department of Health: Office of Radiation Protection, Washington State Department of Ecology Nuclear Waste Program, and the Environmental Protection Agency. Maintaining compliance at Hanford reduces environmental impacts and addresses violations, or non-compliances. The following strategies improve compliance and support the avoidance of enforcement actions. At Hanford, regulatory agency environmental enforcement actions, and their corrective actions, are tracked to completion using databases maintained by inspection subject matter experts. The databases are used to provide the Department of Energy and contractor management with up-to-date status of regulatory agency activity and the required corrective actions. Trending enforcement actions helps target compliance vulnerabilities. Findings and corrective actions that are entered into the databases are then trended by date, location, responsible contractor, agency, and type of compliance issue. The ability to review previous non-compliances in certain locations of the Site, or by general alleged violation, provides the project's environmental contacts with information on what types of issues to look for on pre-inspection walk downs. Finding non-compliances during pre-inspection walk downs allows the contractor to correct the issue and avoid potential fines from regulating agencies. The walk downs are conducted by environmental specialists and project personnel looking for issues that may be viewed as a compliance problem. Using agency checklists and previous inspection correspondence can help to provide valuable information during pre-inspection activities. Training regulatory agency inspectors on Site security requirements, cultural and ecological standards, and inspection protocols allows for increased efficiency and reduces potential miscommunication between regulatory agencies and the regulated contractors. The training also allows the contractors to give the regulating agencies the up-to-date policies and procedures that will be addressed during the inspection. Hanford has pre-identified inspection coordinators within each contractor to assist in coordinating with Department of Energy personnel, projects, and management prior to the inspections. These inspection coordinators notify affected management, accommodate and escort the regulators to locations they ask to inspect, set up requested interviews, and gather requested information that will need to be cleared for public release. These practices make for positive experiences and interactions with the regulating agency personnel and help reduce and eliminate environmental non-compliances, findings, violations, and fines.

Application of a bayesian belief network model to reliability assessment of nuclear safety-related software - 207

As the instrumentation and control (I and C) systems in nuclear power plants (NPPs) have been replaced with digital-based systems, the need to incorporate software failures into NPP probabilistic risk assessments has arisen. In order to assess the probability of software failure on demand, a Bayesian belief network (BBN) model was developed which estimates the number of defects and the resulting probability of software failure on demand in nuclear safety-related software. To assess the feasibility of the BBN framework, the BBN model was applied to the prototype Integrated Digital Protection System-Reactor Protection System (IDiPS-RPS) to estimate the number of remaining faults and the software failure probability of a target software. The developmental- and V and V-activities carried out during the IDiPS-RPS development process were evaluated based on the well-defined checklist derived by the V and V team and were estimated based on expert elicitation. In addition, the attribute evaluations and the number of FPs of the target software is provided as the inputs for the BBN model. The application results showed the feasibility of using BBNs for quantifying software failure probabilities and several insights were gained from the applications of the BBN model. The proposed BBN framework can be applied to estimate the software failure probability for other safety-related NPP software and provide an insight on modeling the software development process that involves iterations between different development phases.

HANDBOOK BEST PRACTICES FOR ORGANIZING PUBLIC E WASTE COLLECTION EVENTS Indoor and Outdoor Settings

This handbook was created to share best practices of organizing public e-waste collection events in the United States. The steps and checklists outlined in this handbook have been drawn from Sunnking’s decade’s long experience of organizing large scale outdoor collection events in New York. These practices have been verified by INL and ECyclers of Idaho to work well for both indoor and outdoor events in Idaho at a smaller scale. Understanding that the local conditions vary significantly, we have compiled key deciding factors to share in this handbook. We hope that by following these steps, you will succeed in organizing your own events. Although e-waste events typically require careful logistics planning due to the nature of the materials, the experience is very rewarding to bring the community together.

Microbiome data management in action workshop: Atlanta, GA, USA, June 12–13, 2024

Microbiome research is revolutionizing human and environmental health, but the value and reuse of microbiome data are significantly hampered by the limited development and adoption of data standards. While several ongoing efforts are aimed at improving microbiome data management, significant gaps still remain in terms of defining and promoting adoption of consensus standards for these datasets. The Strengthening the Organization and Reporting of Microbiome Studies (STORMS) guidelines for human microbiome research have been endorsed and successfully utilized by many research organizations, publishers, and funding agencies, and have been recognized as a consensus community standard. No equivalent effort has occurred for environmental, synthetic, and non-human host-associated microbiomes. To address this growing need within the microbiome research community, we convened the Microbiome Data Management in Action Workshop (June 12–13, 2024, in Atlanta, GA, USA), to bring together key decision makers in microbiome science including researchers, publishers, funders, and data repositories. The 50 attendees, representing the diverse and interdisciplinary nature of microbiome research, discussed recent progress and challenges, and brainstormed actionable recommendations and paths forward for coordinated environmental microbiome data management and the modifications necessary for the STORMS guidelines to be applied to environmental, non-human host, and synthetic microbiomes. The outcomes of this workshop will form the basis of a formalized data management roadmap to be implemented across the field. These best practices will drive scientific innovation now and in years to come as these data continue to be used not only in targeted reanalyses but in large-scale models and machine learning efforts.
