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 of potentially erroneous level indication due to non-condensible gases, and to implement compensatory measures and long-term corrective actions as necessary.
We find acceptable:
(1)
Gulf States Utilities (GSU) review and acceptance of the BWR Owners' Group (BWROG) generic analysis as being applicable to the River Bend Station.
(2)
GSU's endorsement of the BWROG comitment, outlined in its letter dated August 12, 1992, regarding schedule and plans for actions to address postulated errors in BWR water level instrumentation.
(3)
GSU's endorsement of the BWROG's Emergency Procedures Comittee guidance letter dated August 19, 1992. This letter provides guidance for operator action in the event of level indication errors due to non-condensible gases during reactor pressure vessel (RPV We also understand that you have sensitized your opera) tors to thesedepressuriza potential errors consistent with the BWROG guidance.
(4)
GSU's comitment to submit a follow-up response to this generic letter identifying your planned actions and schedule to reach resolution on this issue. We request that you provide this response by July 30, 1993.
