d I k PUBLIC SERVICE COMPANY OF COLORADO DENVER, COLORADO 80208 P. o. B O X 840 OSCAR R. LEE veCE PRESIDENT December 4,1981 Fort St. Vrain Unit No. 1 P-81307' Mr. John T. Collins, Regional Administrator U. S. Nuclear Regulatory Commission Region IV 611 Ryan. Plaza Dr., Suite 1000 Arlington, TX 76011

SUBJECT:

I & E Inspection Report 81-20

REFERENCE:

NRC Letter dated November 6, 1981 (G-81221)

Dear Mr. Collins:

This letter is in response to the Notice of Violation received as a result of inspections conducted at Ft. St. Vrain during the period September 1, 1981 to September 30, 1981. The following response to the items contained in the Notice of Violation is hereby submitted:

1 A.

Technical Specification 7.4.a

" Procedures, Administrative Controls," states in part that, ".

written procedures shall be established, implemented, and maintained.

Procedure ASP-3, " Maintenance Quality Control Program,"

effective date August 18, 1981, Section 4.1, " Maintenance and Preventive Maintenance Procedures Control," states in part that,"

Hold Point: An inspection point in a procedure where the craftsman has notified the Maintenance Quality Control Technician, who in turn must sign off the inspection before work shall be allowed to continue.

Contrary to the above, on September 15, 1981, at 11:00 a.m.

(MDT), the NRC inspector determined that five hold points for work previously performed had not been signed by the Maintenance Quality Control Technician.

[7k....

Dacember 4, 1981 P-81307 (1) The corrective steps which have been taken and the results achieved:

Compliance regarding the above violation was achieved on September 15, 1981 at 1100 hrs by properly com-pleting the procedural QC checks.

(2) Corrective steps which will be taken to avoid further violations:

The occurrence of the violation was caused by poor procedural methods in that the procedure being used (MP 98-1) was written such that it implied the need for " Snubber Testing Machine" recalibration each time a snubber was installed in it.

In this case the machine had been calibrated for the particular snubber being tested just prior to the violation, but the snubber was removed from the testing machine to tighten connecting rod bolts and immediately reinstalled in the " Snubber Testing Machine" Jor continuation of the test.

As a result of this all steps previously completed, including QC checks were not redone per the procedure. A revised procedure, (MP 98-1),was issued October 17, 198L which will clarify this and other similar areas to avoid further violations.

(3) The date when full compliance will be achieved:

Full compliance specifically regarding the above violation was achieved on September 15, 1981 at 1100 hrs. The effective date of the new procedure, MP 98-1, rewritten to avoid further violations was October 17, 1981.

B.

Technical Specification LCO 4.4.1, " Plant Protective System Instrumentation," Table 4.4-1, Item 4, " Primary Coolant Moisture, Loop Monitor," specifies an absolute low trip setting of 27" F which is equivalent to a setting on each of the instruments at 3.09.

Contrary to the above requirements, at 10:00 a.m. (MDT), on September 23, 1981, MM1117 was observed to be at a setting of 5.09 and MM1121 was observed to be set at a setting of 3.29.

A 5.09 setting is equivalent to a 92.5'F dewpoint, and a 3.29 setting is equivalent to a 29.3*F dewpoint.

December 4, 1981 P-81307 (1) The corrective steps which have been taken and the results achieved:

Compliacce regarding the above violation was achieved on September 23, 1981 at 1010 hrs by resetting the

" Moisture Monitor" low trip setting to a value of 27"F (3.09).

(2) Corrective steps which will be taken to avoid further violations:

The " Moisture Monitors" setpoints are checked and recorded once per day via the Plant Protective System Log. The only action taken to avoid further occur-rence of the above will be to inform all personnel who'might be involved with moving the setpoint potentio-meter during testing, etc.,of the importance of returning i

'the potentiometer to the correct value. This will be tL

' accomplished by letter.

(3) The date when full compliance will be achieved:

Comhlianceregardingtheaboveviolationwasachieved on September 23, 1981 at 1010 hrs.

Issuance of the

^

information letter reference above will be completed by December 10, 1981.
