Sec J Appendix P - Work Breakdown Structure (WBS).xlsx

This document provides a Work Breakdown Structure (WBS) for the management and operation of the Y-12 National Security Complex and Pantex Plant. It outlines the program in detailed hierarchical levels from the Secretary of Energy down to specific work packages. Key activities include systems engineering, testing, production, and program management. The WBS identifies budgets and milestones for ongoing life extension programs for warhead systems like the B61, W76, W88, and W80. It also covers ongoing surveillance, maintenance, and certification of the stockpile. The level of detail in the WBS provides contractors and the National Nuclear Security Administration visibility into resource requirements and work scope for operating the Y-12 and Pantex facilities over the fiscal year.
