IE REGULATORY BASIS FOR LLW PERFORMANCE ASSESSMENT l

• Performance objectives established in 10 CFR 61.41, " Protection of the General Population from Releases of Radioactivity" j - releases must not result in an annual dose of 25 mrem whole body,75 mrem to the thyroid, and 25 mrem to any other organ l

l

• Performance assessment (PA) defined as the technical analysis used to demonstrate l compliance with performance objectives 1

1

• PA facilitates integrated evaluation of engineering design and site

• Part 61 incorporated into Agreement State regulations 1

l J

NRC BRANCH TECHNICAL POSITION

• Developed to provide guidance on PA not addressed in Standard Review Plan

• Key issues in PA where further guidance is required include:

- An overall understanding of the performance assessment process j 1) PA is an integral part of site characterization program

2) Iterative process between site characterization and PA Modeling of key processes and their interactions including infiltration rates, source term releases, and engineered barrier degradation 1

Uncertainty and sensitivity analyses i
