Review of modeling efforts associated with Yucca Mountain, Nevada: State of Nevada, agency for nuclear projects/nuclear waste project office
Detailed comments are presented on five modeling investigations related to the NNWSI at Yucca Mountain, Nevada. In general, the quality assurance/quality control (QA/QC) procedures of the modeling efforts are considered to be poor. The reports reviewed indicate model documentation and verification/validation is lacking. Many of the technical assumptions underpinning the theory of the models are not supported by observed field conditions and may be inappropriate for application to the Yucca Mountain flow system. Much of the data is assumed and not field measured. Many of the problems simulated have insufficient information provided to allow reproduction of the computed results. Finally, the accuracy of some of the results is questionable, and lack confidence because good QA/QC procedures, such as mass balance calculations, are not performed or reported with the computational results. The review of these five reports underscores the apparent lack of coordination between field investigations and the overall modeling efforts which will be used to support the licensing proceedings via travel time calculations. 8 refs.
