Dear Mr. Schwencer:
Your letter of April 1, 1977 requested that we implement procedures to prevent reactor coolant pump (RCP) starts while in the water solid condition or, in the event such starts could not be avoided, to include procedural steps to ensure that an acceptable reactor coolant system (RCS) temperature profile exists prior to starting a reactor coolant pump.
As discussed in our letter of February 24, 1977, there are times when reactor coolant pump starts are necessary while in the water solid condition.
Therefore we will revise our operating procedures to include non-optional prerequisite stdps while in a water solid condition to determine the reactor coolant system temperature profile before starting a reactor coolant pump.
Appropriate measures will be specified to achieve an acceptable profile prior to starting the pump.
In addition, we will conduct a review of our procedures to ensure that they are consistent with our February 24, 1977 submittal.
These procedural revisions and reviews will be completed prior to startup at the end of our present refueling and main-tenance outage.
Sincerely,
~
P.'.
