Nuclear Regulatory Commission

The proposed license amendment would revise the technical specifications (TS) to eliminate the requirement for automatic main steam line (MSL) isolation based on the temperature in the area around the MSL. In lieu of automatic isolation, a new specification is proposed that requires manual action when the MSL area temperature is above the limit.
