Process Model Reports (PMRs)Purpose
* The purpose is to document the technical basissupporting each TSPA process model
- Supports the postclosure safety case for SRILA* PMRs will focus the development of technical
information on what is relevant to developing adefensible TSPA
- i.e., the information the Project is relying upon todemonstrate postclosure compliance
* The PMR development process will ensure traceabilityof data, information, and references

PMR Scope(Continued)
* PMRs will contain:- Descriptions of the models, submodels, and abstractions
>> Relationship to principal factors
- Relevant data and data uncertainties- Assumptions and bases- Model results (outputs)- Code verification/model validation information- Opposing views e- Information to support regulatory evaluations
>> NRC Key Technical Issues

Summary
* The PMR process is being implemented to ensuretraceability and transparency of models
- Will document the technical basis for TSPA process models* PMRs, and supporting analyses and model reports,
will address the principal factors of the safety case- Focus will be on those factors most significant to
performance* The PMR schedule allows for information to be
incorporated as it becomes available
