/LTIVOMFNP 10' PLY 70 FCI1CE OF VIOIATICN ",0-458/91-15 IJN11 IV PDTTG12CE Notice of Violation - Letter from S.J. Collins to J.C. Doddens, dated June 18, 1991.
VI_OIATION River liend Statica Technical Spccification 3.6.5.2 states that secondary containnent integrity-fuel building shall be rmintained.
River Ibnd Station 7behnical Specification 4.6.5.2 requires that recondary containnent integrity-fuel building shall in deronstrated within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> prior to the handling of irradiated fuel in the fuel building.
Culf States Utilities' Surveillance 7bst Procedure-000-0103, " Irradiated Puel llandling in Puel Building," is the governing prcccdure that inpkrents the 7bchnical Specification 4.6.5.2 surveillance requirennnts.
Contrary to the above, on June 4,1991, the licensee discovered that it had handled Irradiaced Puel Bundle LYif845, without first denenstrating secondary containnent integrity-fuel building by perfornting Procedure STP-000-0103 within the prior 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.
PFASON FVR Tl!E VIOIATION The procedures used during this evolution provided inadequate guidance to assure the requiremnnts of 7behnical Specification (TS) 3.6.5.2 wre met. These prcxmdures included REP-0010, Special Nuclear bbterial (SNM)
Movenent, Control and Accounting; Pl!P-0007, Uce of Puel Preparation Machines; and FilP-GN, Puol llandling Platfonn Operation. The lack of checklists, coupled with the duration of the wrk,
led the Shift supervisor to assum that all pertinent requirents had been net during preparations made in previous shifts. A contributing factor was that this was the first time that fuel novennnt had been perforned when the plant was not in a refueling outage (Operational Condition 5). GSU had previously conducted reviews to ensure that TS surveillances woru included in associated procedures and in the surveillance test procedure (STP) event related matrix. Hcwver, because fuel is normally noved in Operational Condition 5,
a specific event matrix for Operc H onal Condition * (Handling of Irradiated Puol in the Puel Building) wa.
not produced.
CORRETIVE STEPS hilICil !! AVE BEEN TAKEN AND TIIE RESULTS ACilIEVE_D
'Ihe following corrective actions were taken:
1.
Puel handling operations were stopped and the surveillance under j
TS 4.6.5.2 was perforned and found acceptable.
2.
A review of 'Ibchnical Specifications was p rforted identifying 12 limiting conditions for operation associated with Operational Condition * (Handling of Irradiated ruel in the Puol Building).
An independent review of these Technical Specifications was perforwx1 to verify that all other requirenents were satisfied prior to fuel novenent.
3.
Procedure FIIP-0007, Use of Puel Preparation Machines, was revised to add a prerequisite requiring Secondary Containnent Integrity - Puel Building per TS 3.6.5.2.
4.
Procedure FHP-0002, Puol Handling Platform Opration, was revised to add a step for senior reactor operator (Slo) verification of the Technical Specification requittnents prior to the handling of irradiated fuel.
5.
Procedure REP-0010, Special Nuclear Material (S!N) bbvenent Control and Accounting, was revised to incorporate a checklist with sign-offs by a reactor engineer and an SIC which includes verifying the surveillance requirenent of TS 3/4.6.5.2 prior to handling irradiated fuel in the fuel building. Shift Supervisor review and approval is required prior to fuel handling.
6.
All of the operating crews were briefed by the Assistant Plant Manager - Operations, Radwaste and Chemistry on the significance i
of the missed surveillance and the importance of attention to detail.
7.
The event was reported as required by 10CFR50.73 in LER 91-011.
CORRECTIVE STEPS WilICH WILL BE TA}2N TO AVOID FURTIIER VIOLATIONS
'Ib prevent recurrence of this problem, the following action will be i
taken:
The STP matrix will be revised to include an event-related matrix for Operational Condition
- This matrix will include all Technical Specification surveillances required prior to noving irradiated fuel in the fuel building regardless of the plant operational condition.
DATE hi!EN FULL CDMPLIANCE WILL BE ACHIEVED i
nill empliance was achieved with the canpletion of surveillances required by TS 4.6.5.2 prior to the resunption of fuel novment.
Mditional corrective actions will be canpleted by September 30, 1991.
