Los Alamos National Laboratory Lessons Learned for Fiscal Year 2018: SAVY-4000 Lid Bar Stock Issue

During acceptance testing at Nuclear Filter Technologies (NFT) in May, 2018 of a batch of 150 SAVY-4000 containers (3 Qt), 89 containers were rejected due to failing and higher than normal helium leakage test results (see attachment NC#18-033). A total of 56 of those rejected failed the maximum allowed helium leakage rate criterion of 1.0E-05 std cc/sec specified in 55Y-002926 Rev. G, SAVY-4000 fabrication Specification. In addition, 33 containers were also rejected by the manufacturer with helium leakage rates measured between 1.0E-05 and 1.0E-06 std cc/sec (NFT NC# 18-033) because the containers were manufactured from the same lot of base material and the helium leakage rates were outside of the expected range. Upon discovery of the helium leakage test failures of the 3 Qt SAVY’s, NFT pulled the inventory of containers that failed the helium leakage tests and performed a detailed inspection of the lid assemblies. Small voids were discovered by visual inspection on opposing sides of the lids.

Los Alamos, Oppenheimer, and Nuclear Testing, 1943-1954 [Slides]

These slides highlight a general history (and presentation) of the Laboratory’s first twelve years of operations. The slides focus on the creation of the Laboratory following the discovery of fission, its World War II years, and early postwar testing. Some emphasis will be given to the early use of tanks and airplanes to collect radioactive debris created by atmospheric detonations during Operation Crossroads, Sandstone, Greenhouse, Ivy, and Castle.

PF-4 Seismic Performance Reassessment, Los Alamos National Laboratory, Project Charter and Integrated Project Team

This report presents the charter of the Integrated Project Team for conducting the PF-4 Seismic Performance Reassessment (P-SPRa) Project. The overall objective of the project is to compute the seismic performance of the PF-4 structure. The credited safety feature of the structure is to provide tertiary confinement of hazardous materials. This document highlights major tasks to be performed as part of the project. It includes a project schedule and a work breakdown structure dictionary. It also includes roles and responsibilities for key project personnel.

How Los Alamos helped extend the life of the W76 warhead for the U.S. Navy

The Department of Energy’s National Nuclear Security Administration (NNSA) celebrated the completion of the Program of Record for the W76-1 Mk 4A Life Extension Program (LEP) on Jan. 24 at the Pantex Plant in Amarillo, Texas. The W76-1 is a modernized W76-0 warhead, which is a submarine-launched ballistic missile system first introduced into the stockpile for the U.S. Navy in 1978. This LEP has strengthened the safety and security of the United States and its allies by extending the warhead’s service life for another 20 years.

Los Alamos National Laboratory Ombuds Office Biennial Report FY2017-2018

Visitors contact the Ombuds Office to obtain coaching, explore options, develop strategies, learn about LANL resources, understand formal processes and policies, or request a facilitated discussion/mediation. The number of visitors who contacted the office in FY17 and FY18 was 540 and 555, respectively - the highest annual numbers since FY08. The Ombuds Office supports professional workplace communication and conflict management skills through individual consultations, presentations, the resource library, and special events. Courses are regularly scheduled and available to the LANL workforce. Annually, an average of ~1950 participants attended Ombuds courses, workshops, and talks in FY17-18. The total number of individuals who attended presentations in FY17-18, both internal and external to LANL, was 4005. Staff continue to present annually at the International Ombudsman Association Conferences and New Mexico Alternative Dispute Resolution Symposiums. In this reporting period, the Laboratory Ombudsman was recruited to present communication and negotiation skills courses for several universities and prestigious national science and engineering organizations. The mission of the Ombuds Office is to enhance communication and mitigate conflict. Staff provide expertise, feedback and resources to employees, leaders and organizations in order to strengthen conflict and communication capabilities. A related function of the office is to identify and report trends, without breaching confidentiality or anonymity. Trends and concerns may be raised around policies and procedures - including potential future issues – or concerning unhealthy patterns within an organization. The underpinnings of Organizational Ombuds work at LANL are provided by the International Ombudsman Association (IOA) Standards of Practice, (IOA Standards of Practice, 2009; Code of Ethics, 2007). The four IOA tenets are neutrality/impartiality, independence, confidentiality and informality.
