Problem Statement
Accurate simulations are needed to assess Pu production in reactors
•Validation of code calculations for depletion/decay processes
•Accurate neutronic models and their use in attribution and assessment
Technical Approach
•Focus on reactors important for nonproliferation analyses
•Detailed 3-D models of reactor depletion/decay processes
•Inverse methods to identify reactor operating conditions inferred from environmental samples
•Investigation of proliferant scenarios
Benefit
•Methods and tools to facilitate rapid assessment of reactor operations from environmental data
•Familiarity with unusual operations, scenarios, and reactors of interest
