    1. Summary Report of the EPRI Standard Radiation Monitoring Program Dennis Hussey, EPRI Asian Technical Center ALARA Symposium Yuzawa, Japan October 11-13, 2006

    2. Overview History of Standard Radiation Monitoring Program (SRMP) Standard Radiation Monitoring Program Goals Plant Types and Survey Points Current Results US Responses Summary statistics of loop piping channel head surveys Difference of cold leg and hot leg measurements Conclusions and Recommendations

    3. History of Standard Radiation Monitoring Program (SRMP) Started in 1978 to study radiation fields in Westinghouse-designed plants Program expanded to include Combustion Engineering (CE) designs In 1996, program was suspended because of a lack of industry interest and funding In 2003, NEI/INPO/EPRI developed the RP2020 Dose Reduction initiative Take Radiation Off the Table EPRI was charged to take the technical lead for source term reduction First goal was to benchmark PWR performance

    4. Standard Radiation Monitoring Program Goals Maintain the history of the program Much data have been acquired already Locations should not be change Make the procedure simple, focused, practical, and routine North American Technical Center recommendation Help HP staff so that HP staff can help us Organize the data to allow correlation to chemistry events and plant design PWR Monitoring and Assessment Database Encourage consistent sampling techniques

    5. SRMP Monitoring Points Workshop held in Charlotte March 7-9, 2006 to discuss Selection of B&W points Required vs Recommended points Procedure clarifications Marker Discussions Emergency Core Coolant System strainers limit markers with vinyl New markers made that are etched stainless steel Discussed further SRMP plans Pre-oxidation points Auxiliary system monitoring Possible smears
