ENCLOSURE ST.
LUCIE, UNIT 1
RE VEST FOR ADDITIONAL INFORMATION l.
Branch Technical Position, RSB 5-2 (Attached), requires the Overpressure Mitigating System (OMS) to perform its function with a single'ailure when the initiating event is not considered as the single active failure.
Please address the following postulated event:
Consider the initiating event to be the loss of a DC control bus that isolates letdown flow and also violates the operability of one
.PORV.
Then consider the failure of the other PORV as your single OMS failure.
2.
Item 4 of 'Branch Technical
- Position, RSB 5-2, requires the OMS be tested to assure operability prior 'to each shutdown.
a.
Is this testing being performed prior to each shutdown?
How are the OMS setpoints verified prior to shutdown and rev'erified monthly while RCS temperature is <275'F7
,.3.
,The staff requirement that a report be submitted to NRC of all OMS (PORVs or SCS safety valve) operations to relieve pressure transients in the RCS is not included in your technical specifications as amended by your letter of April 13, 1978.
Address this requirement.
4.
In your letter of February'28,
- 1977, you stated that all of your operators will have completed a review of causes of past overpressure transients by April 8, 1977.

a.
What overpressure protection training have you performed since mid-1 977'?
b.
How do you ensure a continued emphasis is placed on possible overpres-surization situations in your. licensing and retrain'ing" programs?
c;.
How is this training and LER review documented
