RESPONSE TO NRC-0IE LETTER FROM C. E. MURPHY TO H. G. PARRIS DATED MAY 30, 1980

REFERENCE:

RII:WBS 50-518/80-08, 50-519/80-08, 50-520/80-08, AND 50-521/80-08 This report responds to the Notice of Violation described in Appendix A of the OIE Inspection Report referenced above. This is the final response on the subject noncompliance.

Noncompliance Item - Deficiency 520/80-08-04 As required by Criterion V of Appendix B to 10 CFR 50, and as implemented by PSAR Section 17.la.5, " Activities affecting quality shall be prescribed by documented instructions, procedures, ...and shall be accomplished in accordance with those instructions, procedures,...". TVA Procedure RIS&PM Interim Procedure Mechanical M-650, Rev. O dated 10-24-79 entitled Reactor Pressure Vessel (NSSS)-QA-ASME Section III-MPL No. B13-D001 set forth requirements as follows for storage and maintenance of the RPV:

1. Procedure M650-Rev. 1, Section B, Storage, paragraph 1. Horizontal Position - Storage Yard, subparagraph i states "The item shall not be stored in areas adjacent to: unpaved roads heavily traveled by site vehicles or other dust making operations.

Contrary to the above, a frequently traveled haul road was opened adjacent to the vessel storage area and the area has become showered with dust.

2. Proced'ure M650-Rev. 1, Section C Preventive Maintenance paragraph 3 states "For heated vessels, the temperature of the heated surfaces shall be checked at three equally spaced locations at least once a day".

Contrary to this requirement, temperature measurements were not being taken as of April 25, 1980.

This is a deficiency.

' ' ^ ~

r-y RESPONSE - ITEM 1 Corrective Steps Taken and Results Achieved Vessel storage requirements are extracted from CE requirements and stated in RIS&PM M-650, Revision 1, " Reactor Pressure Vessel (NSSS)

QA ASME,Section III, "The item shall not be stored in areas adjacent to unpaved roads heavily traveled by site vehicles or other dust-making operations like sandblasting."

The vessel storage area is located at a "Y" on a gravel / dirt road with one fork going to the barge unloading area and the other going to the

~

turbine parts storage yard. On an average day, the vessel will be passed approximately 15 to 20 times by site vehicles. TVA's position is that although these roads are dust-making, they are wet down as a measure of environmental dust control and are not heavily traveled in ,

comparison to primary construction roads. Also, the integrity of the vessel and circulation system prevent dust from entering the vessel.

This position was supported by CE site representatives who stated that there is no problem with the current location or condition.

l Corrective Steps Taken to Avoid Further Noncompliance A revision request to RIS&PM M-650 is being prepared to eliminate potential misinterpretation.

Date When Full Compliance Was Achieved We will be in full compliance when the RIS&PM is revised. This will be on or about July 1, 1980.

RESPONSE - ITEM 2 b

Corrective Steps Taken and Results Achieved TVA had initially planned to purge the vessel with nitrogen during storage. When the vessel was converted to heated air shortly after arrival, temperature and humidity monitoring devices were not available and were ordered. While awaiting arrival of monitoring equipment, the vessel was inspected periodically by site engineers and CE. No evidence of condensation was found inside the vessel. On May 16, 1980, the temperature and humidity monitoring equipment was installed and daily reading, as required by procedure M650, Revision 1, was begun. To date, all readings have been in compliance with storage requirements.

Corrective Steps Taken to Avoid Further Noncompliance Temperature and humidity monitoring equipment is onsite and ready for installation ca the next vessel on arrival.

Date When Full Compliance Was Achieved Full compliance was achieved on May 16, 1980.
