ALLEGATION

SUMMARY

SUBJECT:

RII-90-A-0005 This is in reference to an anonymous letter received by the NRC on January 8,1990, and a letter received by the NRC on March 3,1990, in which alleg,ations were made regarding: 1. alleged violations of technical specifications associated with dilution valves, 2.

failure to perform adequate surveillances, 3. installation of i

Microfiltration test unit designed in violation of Reg. Guide 1.140, 4. failure to perform adequate shutdown margin calculations, and 5. failure to report missing fire penetration seals and reporting of events.

1. ALLEGED VIOLATIONS OF TECHNICAL SPECIFICATIONS ASSOCIATED WITE DILUTION VALVES It was alleged that in October 1988, Operations . management willfully violated Technical Specifications (TS) by opening valves that were requ' ired to be in a locked shut condition; and an incident the NRC resident staff identified where dilution valves were not properly locked in their required TS position.

DISCUSSION:

Based on this allegation, an NRC investigation was conducted and escalated enforcement action (EA-91-141) was taken relative to the chemical addition to the reactor cooling system that occurred on October 12-13, 1988. On December 31, 1991, the NRC issued a Notice of Violation and Proposed l Imposition of Civil Penalty to Georgia Power Company, and issued an Order Imposing Civil Monetary Penalty on June 12, 1992. l l

2. FAILURE TO PERFORM ADEQUATE PORV, STEAM GENERATOR BLONDOWN ,

VALVE AND E-BAR SURVEILLANCES

DISCUSSION: j NRC's review of this allegation is detailed in NRC Inspection Report 50-424,425/92-31, dated January 26, 1993. This review included a review of all Deficiency Cards associated with these surveillances during the time period selected. Based on the results of this review, the allegation co"1' _at be substantiated.

  • i INSTALLATION OF MICROFILTRATION TEST UNIT DESIGNED IN 3.

VIOLATION OF REG. GUIDE 1.140 l

DISCUSSION:

NRC's review of this allegation is detailed in NRC Inspection Report 50-424,425/90-19, Supplement 1, dated November 1,1991.

This review indicated that the FAVA system was o,riginally installe,d and operated by the Vogtle staf f without an adequate saf ety evaluation and did not meet the guidance in Reg. Guide  ;

1.143 in that, PVC piping was used in this system. HowevIr, l this deficiency was of limited duration, and 4PC apon i

performing subsequenc safety evaluations that were forwarded to and accepted by the NRC, concluded that the system was  ;

l acceptable for use. The facts do not support a conclusion that GPC willfully violated NRC requirements or willfully i operated the facility in a manner to endanger public health <

and safety.

4. FAILURE TO PERFORM ADEQUATE SHUTDOWN MARGIN CALCULATIONS (

DISCUSSION: i IRC's review of this allegation is detailed in Inspection l Report 50-424,425/91-20 dated September 12, 1991. This review i indicated that the shutdown margin calculation performed at j 7:13 p.m. on January 19,1989, was performed incorrectly in that, the incorrect procedure data sheet was used by the person performing the calculation. The review also identified  ;

that the Licensee identified this error and took appropriate l corrective action. The corrected calculations and independent  ;

review by Imc did not support the allegation that the error resulted in a dangerously low boron concentration 1.n the l Reactor Coolant System or that it endangered the health and safety of the public.

5. FAILURE TO REPORT MISSING FIRE PENETRATION SEALS AND REPORTING OF EVENTS i

DISCUSSION: = l NRC's review of this allegation is documented 16 Inspection l Report 50-424,425/92-13, dated August 4, 1992. The NRC review l of this area included a review of all Deficiency Cards  !

associated with fire penetrations and seals since 1988 to assure that discrepancies and deficiencies identified were and l had been properly reviewed and appropriate actions taken. NRC j did not find any evidence to support the allegation that l missing fire penetration seals were not reported as required. l 1
