Functional Analysis of Selected NNSA Sites - National Nuclear ...

Functional Analysisof Selected NNSA SitesMarch 20102.0 Functional HierarchyThe original 2007 function listing was used as the starting baseline for this update. Since itsissuance a number of key decisions have been made and include: SPEIS (DOE-EIS 0236-S4) Records of Decisiono Operations Involving Plutonium, Uranium, and the Assembly and Disassembly ofNuclear Weapons – December 19, 2008o Tritium Research and Development, Flight Test Operations, and Major EnvironmentalTest Facilities – December 19, 2008o Continued Operations at various sites Congressional Language for Tritium Research and Development (R&D) NNSA Nuclear Security Enterprise Acquisition Strategy Functional Analysis by SITS (2009) for the Corporate Physical Infrastructure Business Plan NWC Work Breakdown System (draft) Ten Year Site Plans (2009-2018) Information Technology (IT) Optimization StudiesThe 2007 hierarchy was structured around the NNSA-Defense Programs weapons productionactivities, i.e. mission direct activities. As functions for other NNSA missions were further defined,the need to revise the hierarchical layout was assessed. Alignment with the DOE’s Chief FinancialOfficer’s (CFO) Office of Internal Review’s Report on Functional Support Cost Activities wasdetermined to be a prudent approach to relate the functional hierarchy with the categories used inthe cost activity report. The Office of the CFO is responsible for coordinating and assembling theDepartment's Support Cost by Functional Activity information. Support cost activities are thosenecessary functions that enable the Department to accomplish direct mission activities. Supportcosts are allocated into twenty-two distinct categories, such as procurement, maintenance andsafety and health. This schema provides a means to more easily identify the cost of a function.Figure 3 is a diagram that shows the top level of the NSE functional hierarchy and correlates theCFO’s existing cost activity structure with the functional hierarchy.Figures 4 through 7 provide hierarchy diagrams for each top level functions. Definitions of the tier 1and 2 functions are provided in Table 1 along with a list of functions for the entire hierarchy thatidentifies performing sites 3 for each. Detail information and definitions relative to the CFO costactivity structure can be found on their web site (Reference 3).3 Performing Site: Refers to the home site of the personnel performing the function, regardless of their physical location. Some"sites" (e.g., SNL) exist in multiple locations (e.g., Albuquerque, NM; Livermore, CA; and Amarillo, TX), and some sites'personnel perform NSE functions at other NSE sites.Page 7 of 56
