Iicensee Action on Previousl Identified Items a.
(Closed) Notice of Violation No. 50-530/85-09-06
"Weldin Inte rit of New Fuel Racks" O.
In order to evaluate the conditions discovered on the new fuel racks, a number of actions were taken.
The Joseph Oat Corporation performed a re-analysis of their report "Stress Analysis of Fuel Storage Racks for ANPP PVNGS."
This effort is documented in J.
Oat Report No. TM-748 "Weld Analysis for New Fuel Racks" which was certified by a Professional Engineer as conforming to the remi'rements of the design specification and the applicable sections of the governing codes.
The weld analysis included an evaluation of the affect of missing or marginal welds on the structural integrity of the fuel racks.
In conjunction with this analysis, CE performed a 100$ weld inspection of fuel rack J-8012-1A3, and an inspection of all welds with a seismic design stress in excess of 10,000 psi on the remaining five racks.
As a result of this combined analyses/inspection, CE concluded that the Unit 3 new fuel racks are acceptable for storage of new fuel under design storage parameters.
Since a similar level of workmanship was used in fabrication of the Units 1 and 2 racks, CE also concluded these racks to be acceptable.
CE based this conclusion on the results from inspection of Unit 3 racks and on their QA surveillance reports of the Unit 1 and 2 racks, at the time they were, fabricated.
In addition, the intermediate fuel rack, supplied by J. Oats, was visually inspected and found to be-satisfactor ~ I

>>The root cause-analysis and corrective actions to be taken. were
,identified to the, NRC in licensee letter ANPP-32994 WEI/MPQ dated July 10, 1985., The results of these actions taken is documented in letter V-CE-32851 of August 20, 1985 from the CE Project Manager to the ANPP Executive Vice President.
CE's review of the J.
Oat QC inspection procedure for visual examination of welds determined the procedure to be in compliance with the requirements of ASME Section V for visual inspection.
Basically, the root cause was identified as misinterpretation by J.
Oat in regar'ds to purchase order and specification requirements which resulted in a reduction in the amount of production welds requiring visual examination.
Equipment specifications were subsequently revised to, provide adequate clarification of inspection requirements.
CE also evaluated their own Quality Assurance Program regarding qualification of vendors, and concluded that J.
Oat was capable of meeting the conditions of the purchase order; and that the assigned surveillance activities
'ere adequate.
Based on the licensee's corrective action as indicate above and the inspector's examination of 'the licensee's stated actions, this violation is closed.
b.
(Closed) Followu Item No. 50-528/84-45-02
"Bechtel Audit of EAB" Bechtel performed a full scope audit on November 29 through December 20, 1984 at Engineered Air Balance Company (EAB) operations to verify the implementation of the EAB QA Manual and Subcontract Order 10407-13-MM-634.
The inspector reviewed the audit results to assure the audit had addressed programmatic concerns previously identified by the NRC.
The audit did identify these and other deficiencies.
The inspector reviewed the corrective actions taken and concludes that they were satisfactorily closed.

(Closed) Followu Item No. 50-528/85-01-01
"Unsealed Pi in Penetrations" Ten of fourteen penetrations were previously sealed as part of the corrective actions required to close DER No. 84-31.
The four remaining penetrations have subsequently been installed.
This item is closed.
d.
.(Closed) Followu Item 50-528/85-01-03
"EER Transmittal Recei t/Acknowled ement"
. The licensee revised OEDG-020 to include a positive acknowledgement system for EERs transmitted to other parties.
The procedure, requires the distribution of EERs to be transmitted via a site
"Transmittal Receipt/Acknowledgement" form, and'receipt to be maintained on file.
