The above technology issues point to the need for a significant R D program to determine the viability of the concept and provide needed data to adequately evaluate the concept and support the detailed design effort. Data needs include data on material compatibility, cross sections and fuel performance data, thermal-hydraulics data, and component performance data. These data will also be required for the development and validation of analysis tools to be used in the design, development, and safety analyses for the MSR.

Success criteria were extracted from information contained in plant procedures, supplemented by the PRA team s experience with the plant reviews of existing SRS engineering/physics analysis and analyses done in support of the PRA. Additional thermal-hydraulic analysis to refine some of the success criteria is planned for 1991. It is expected that the impact of improved success criteria will be a reduction in the estimated core damage frequency. Therefore, this issue does not require resolution before restart. 

Accurate site investigation data with test drillings and pumping tests are also of importance for modelling and simulations to be used for permit applications. The simulations are used to predict the thermal and hydraulic influences and are used for environmental assessment issues as well as for prediction of potential physical damages caused by the pumping of ground water.
