Dear Mr. Boulette:
SUBJECT:
RESPONSE TO GENERIC LETTER 92-04 " RESOLUTION OF THE ISSUES RELATED l
TO REACTOR VESSEL WATER LEVEL INSTRUMENTATION IN BOILING WATER REACTORS", PILGRIM NUCLEAR POWER STATION (TAC NO. M84297)
I l
This letter acknowledges receipt of your response to Generic Letter (GL) 92-04, dated September 28, 1992. GL 92-04 was-issued by letter dated August 19, 1992, to all operating Boiling Water Reactor (BWR) licensees..
GL 92-04 requested licensees to promptly assess the impact on their facilities j
of potentially erroneous level indication due to non-condensible gases, and to l
implement compensatory measures and long term corrective actions as necessary.
)
q We find acceptable the Boston Edison Company's (BEco)~ responses to the three i
requests in GL 92-04 as follows:
(1)
The determination of impact of potential level indication errors on
{
safety system response during all licensing basis transients and i
accidents provided in your GL response.
(2)
The determination of impact of potential level indication errors on l
operator's short and long term actions during and after all licensing i
basis accidents and transients as provided in your GL response and NRC i
Inspection Report No. 50-293/92-17.
-J (3)
The determination of impact of potential level indication errors on operator actions prescribed in emergency operating and other affected j
procedures not covered in (2) as provided in your GL response and NRC Inspection Report No. 50-293/92-17.
(4)
Notification of short term action (s) as provided in your GL response.

t Mr. E. Thomas Boulette March 2, 1993 We understand that you will implement modifications at Pilgrim Nuclear Power i
Station if your assessment of the BWROG program indicates that modifications j
are necessary to ensure level instrumentation is of high functional reliability.
It is our understanding that you will provide _ a response, in accordance with GL 92-04, after assessing the results of-the BWROG long-term program, stating what long-term corrective actions you plan to implement, and a schedule to complete these actions.
On October 23, 1992, the BWROG approved refined operator guidance developed by the Emergency Procedures Committee for response to instrument errors due to non-condensible gases. A copy of this guidance was sent to your facility. We l
feel that this guidance provides appropriate information for operators to adequately identify and deal with potentially inaccurate RPV level instrumentation, and expect that this or equivalent guidance, has been i
incorporated into your station operations.
Should you have any questions, please contact me at (301) 504-3041.
