Bulletin No. 75-08 December.12, 1975 PWR PRESSURE INSTRUMENTATION l
DESCRIPTION OF CIRCUMSTANCES:
During a recent review of plant heatup and cooldown records at an operating nuclear power plant, it was determined that continuously recorded data was not cvailable to verify adherence to the tempera-f ture/ pressure limitations specified in the technical specifications.
~
Such information is necessary for determining trends and for evalu-2 ating pressure transients, as shown during the reviews of recent rapid i
pressure increases of the reactor coolant system (RCS) at several plants
~
and the overpressurization of the RCS at another.
ACTION REQUESTED OF LICENSEES:
~
PLEASE PROVIDE THE FOLLOWING INFORMATION IN WRITING TO THIS OFFICE WITHIN 30 DAYS AFTER RECEIPT OF THIS Bulletin:
a Provide a description of reactor coolant system temperature and 1.
pressure instrumentation which allows you to verify adherence _to the temperature / pressure limitations in your technical specifica-tions.
2.
If you do not have the capability to continuously record reactor coolant system temperature and pressure during heatup and cooldown as well as during power operation, describe what action you have taken or plan to take to provide assurance that the temperature /
pressure limitations in your technical specifications are met.
