REVISION TO COMMITMENTS REGARDING RADIATION MONITORING SYSTEM MODIFICATIONS SALEM GENERATING STATION UNIT NOS. 1 AND 2 DOCKET NOS. 50-272 AND 50-311 PSE&G is revising its implementation schedule and commitments to modification projects for the Radiation Monitoring System (RMS) as stated in Inspection Report 50-272/89-10; 50-311/89-09, noted LERs and Special Reports. As a result of additional review and evaluati9n of the material condition of the existing Unit 2 and Unit 1 RMS, the required scope to resolve current equipment defects and future problems with aging obsolete components is much larger than originally envisione Therefore a re-evaluation of the project was considered necessary to ensure the best approach will be adopted which has impacted the existing schedul The commitment to install voltage regulators to prevent channel spiking can not be implemented as originally schedule Additionally, the original project commitment has been modified from replacing the existing non-regulated power supplies with voltage regulators to installation of an Uninterruptible Power Source (UPS). The corrective action commitment to replace the RMS Central Processing Unit (CPU) and those monitoring systems that actuate ESFs is being re-evaluated and therefore the original schedule for these long-term projects will not be met. Alternatives have been developed that will provide acceptable resolution of RMS and power supply problems and better utilize available resource Evaluation of the RMS project upgrade alternatives was completed in December, 1990. Upon completion of the RMS upgrade project review the appropriate approach will be approve PSE&G will notify the .NRC of the 1 final decision, project scope and implementation schedule by the end of March, 1991. r-910219(>137 91(12T2 .
