, Licensee Action on Previous Enforcement Matters (927028)(Unit 1)

(Closed) Violation 321/86-05-01, Failure to have a Procedure for Conducting Acid Etch Examinations on Safety-Related Components. GPC's letter of response dated May 12, 1986, has been reviewed and determined to be acceptable by RII. The inspector held discussions with a cognizant engineer-and examined the corrective actions as stated in the letter of respons The inspector concluded that GPC had determined the full extent. of the

! subject noncompliance, performed the necessary survey and followup action to correct the present conditions and developed the necessary corrective actions to preclude recurrence of similar circumstances. The corrective actions identified in the letter of response have been implemente . Unresolved Items Unresolved items were not identified during this inspection.

i Inservice Testing of Pumps and Valves (617008 and 617258)(Units 1 and 2)

The inspector reviewed procedures and records and observed testing, as described below, to determine whether applicable code, procedure, and regulatory requirements were being me The licensee submitted its Interval 2 In-Service Testing Program (IST) for pumps and valves for both Hatch units to the Office of Nuclear Reactor Regulation (NRR) on June 25, j 1985. This program conforms to the ASME Boiler and Pressure Vessel Code,

-

42SV-SUV-040-1S, Rev.1, " Check Valve ISI Internals Inspection" The above procedures were reviewed to determine whether, except as specifically addressed by relief requests, all requirements for the applicable edition of the ASME Code,Section XI are incorporated including:

-

Recording of test results per the approved procedures

-

Evaluation of test data in accordance with specified time constraints and criteria

-

Positive testing of check valves whose safety function is to both open and close

-

Observation of valves with remote position indicators at least once very two years

-

Setting of limiting valve stroke times commensurate with the capabilities of the valve tested During this review, the inspector noted a potential deficiency in some of the licensee's procedures for stroke time testing of power operated valves. IWV-3410 of Section XI requires, in part, that Category A and B valves be exercised at least once every three months, except as provided by the Code. If a power operated valve exhibits an increase in stroke time of 25% or more from the previous test for valves with full-stroke times greater than 10 sec or 50% or more for valves with full-stroke times less than or equal to 10 sec, the test frequency must be increase Additionally, if a valve exceeds its limiting value of full-stroke time during such testing, corrective action must be initiated immediatel If the condition is not, or cannot be, corrected within 24 hr, the valve must be declared inoperativ The

inspector noted that some data sheets used for quarterly testing of power operated valves do not provide the limiting values of stroke time or for a determination that such times have not been exceeded. The inspector found that in such cases limiting values of stroke time are provided on the data sheets used for monthly testing of power operated valves. If monthly testing is performed subsequent to the quarterly testing, determination of the inoperative condition of a valve could be

'

delayed. It appears that administrative controls should be established to require that quarterly and monthly testing be accomplished together or the involved data sheets for quarterly testing should be modified to provide the limiting values of stroke time. A licensee representative agreed to investigate the inspector's concern and take any appropriate actions. Pending completion of the licensee's actions, this matter is identified as Inspector Followup Item 321, 366/87-01-01, Review of Testing of Power Operated Valve The inspector also noted during this review that procedures are not in place to positively test certain Category C check valves that are normally closed and have safety functions in both the open and closed positions. More specifically, the licensee's current program requires the standby liquid control pump discharge check valves (C41-F033A and B) to be exercised to the open position on a quarterly basi The related periodic test procedure (34SV-C41-001-IS, Rev. 0, " Standby Liquid Control Pump Operability Test and Relief Valve Test") does not provide for closure testing after opening. IWV-3522(b) of Section XI requires that normally closed check valves be periodically exercised to the open position, but does not specifically require testing to the closed position for those valves that also have a safety function in the closed position. Despite the ambiguity of the current Section XI requirements, industry experience has shown that exercising to the open position cannot be relied upon alone to demonstrate the overall operability of such dual function check valves. Discussions with a licensee representative revealed that GPC was aware of the need to test dual function check valves for closure and is currently considering how best to accomplish this testing. Pending completion of the licensee's review and followup by the inspector, this matter is identified as Inspector Followup Item 321, 366/87-01-02, Review of Test Requirements for Dual Function Check Valves.

'

d. The test records listed below were reviewed for the 12-month period commencing July, 1985, to determine whether inservice testing test data were evaluated in accordance with the requirements of Subsections IWP and IWV of Section XI, and whether appropriate actions were taken, i.e., increased frequency of testing, repairs, declaration of j component / system as inoperable, etc.

7 Inspector Followup Items (92701B)(Units 1 and 2)

(Closed) Inspector Followup Item 321, 366/86-32-01, Review of Approved Procedure for Monitoring Extraction Steam Piping. The inspector reviewed the licensee's recently issued procedure 421T-N36-001-0N, Rev. O, "Inspec-tion of Plant Steam Piping for Erosion / Corrosion." The inspector noted that this procedure applies to both units, and provides for the ultrasonic monitoring of the auxiliary drains and vent systems and condensate and feedwater systems in addition to the extraction steam system The procedure specifies that the Engineering Department will select specific inspection points and related monitoring frequencies, and provides flexi-bility for adding follow-on inspection points based on operating experienc Review of this item is closed.
