Currently max. reactor temperature is approximately 110 deg C and ASPEN predicts that plant can run at 130 deg C maximum. Committee Members present: Joe Schell, John Monroe and Gerald Wagener Project rep: Anthony Machie Concerns: 1. Concerning the "impurities in EO" test: a maximum safe operating pressure for T-240 should be established and if exceeded the test should be aborted. Monitor rate of pressure rise as a means of detecting air leaks into the system. DO A 016950 CONFTDFNTTAL Anthony Machie June 22,1992 Page 2 2. Concerning the "high reactor temperature" test Don't by-pass the current high reactor trip temperature. If this is anticipated, ARC data with appropriate interpretation should be reviewed to determine if a reactive chemicals hazard will exist Please respond in writing to the committee chairman within one month as to action taken or planned in regard to these concerns.
