B.

General Review of Vendor's Activities 1.

There has been no change in the status of the ASME Certificates of Authorization, the authorized inspection agency or the authorized nuclear inspector as reported in NRC IE RIV Report 99900049/79-01 2.

AM's contribution to the nuclear industry represents approximately 15 percent (15%) of its total workload.

C.

Design and Document Control - Design Verification 1.

Objectives The objectives of this area of the inspection were to verify that:

Procedures had been prepared and approved by the vendor to pre-a.

scribe a system for design verification which is consistent with NRC rules and regulations, and the vendor's commitments in the ASME accepted Quality Assurance Program.

b.

The design verification procedures are properly and effectively implemented by the vendor.

2.

Method of Accomplishment The objectives of this area of the inspection were accomplished by:

O 4

a.

Review of the ASME accepted Quality Assurance Manual, Issue #5, (1) Section 3, " Order Processing and Design Control,"

(2) Section 5, " Instructions, Procedures, and Drawings" and (3) Section 6, " Document Control;"

to verify that the vendor had established procedures to prescribe a system for design verification.

b.

Reviewed the following procedures:

(1) 20-71-04, " Controlling Design of Products under ASME," and (2)Section III Engineering Instruction #39, " Reconciliation of Stress / Design Report,"

to verify that they had been prepared by the designated authority, approved by management, and reviewed by QA.

c.

Reviewed the documents referenced in paragraphs a. and b. to verify that they contained measures to verify the adequacy of i

design, require documented results of the design verification, required the design verification to consider the importance to safety, identiff the method of performing the design verification, j

identify items to be addressed during the design review, and prescribes the requirements for performing verification by alternate calculations, or by qualification test.

d.

Reviewed design verification of 16 in. - 1500# W.E. " Wye" Stop Check Valve w/ Hydraulic Actuator," (A&M Order Number 14225 drawing 14225-01-H) to verify that the design verification procedares are being implemented.

Interviews with personnel to verify that they are knowledgeable e.

in the procedures applicable to design Verification.

3.

Findings a.

Deviation:

See Notice of Deviation Item A.

b.

Follow-up Item Correction had been made to the Design and Stress Report using

" paste ons" and the corrections had not been initialed and dated

5 to provide traceability.

The AM personnel stated these corrections were made during the preparation of the design calculation and prior to the design verification.

The customer

" technical specification" invokes ANSI N45.2.2 but does not invoke ANSI N45.2.9; therefore, AM did not adhere to paragraph 3.2.6 which states in part, ".

. The correction or supplement shall include the date and the identification of the person authorized to issue such corrections."

AM stated they will modify their quality assurance program to eliminate " paste-ons" on the Design and Stress Reports prior to the design verification. Any subsequent modification or revision to the reports would be identified in accordance with the quality assurance program requirements.

AM's corrective action will be reriewed on a subsequent inspection.

Within this area of the inspection no deviation's or unresolved items were identified.

I.

Notification Pursuant to 10 CFR 21.21 Dated January 31, 1980 by Consolidated Edison Company of New York.

1.

Background Information Consolidated Edison Company of New York (con Ed) notified NRC IE RI on January 31, 1980 pursuant to 10 CFR 21.21, that all four (4) reverse flow check valves (MS-2) were at, or near, full open position at Indian Point 2.

Investigation revealed that free movement of the valve discs was apparently prevented by excessive tight shaft

. packing.

12 NRC IE HQ issued Information Notice No. 80-16 dated April 29, 1950 informing licensees of Con Ed's finding and further stated their own evaluation revealed that with the existence of the reported condition in the event of a main steam line break upstream of the main steam isolation valve together with coincident single failure of a main steam isolation valve to close in another loon the potential existed for blow down of the contents of two ste.m generators.

NRC - IE RIV, VIB, Component Section I was assigned the responsibility of performing an inspection at AM and develop information to the extent possible to disposition this problem.

2.

Objectives The objectives of this area of the inspection were to ascertain:

a.

The corrective action implemented b.

The action initiated to prevent recurrance c.

The generic impact.

3.

Method of Accomplishment Reviewed AM Field Service Engineer's Trip Report dated January a.

18, 1980 to determine his finding at Con-Ed's Indian Point Nuclear Station Unit 2.

b.

Reviewed AM's " Instruction Manual - Main Steam Isolation and Main Steam Check Valves.., for.

. Indian Point Nuclear Power Plant #2 Buchanan, New York" to determine the recommended saintenance requirements.

c.

aeviewed AM drawing 20727-H, Alt. 5, titled "28" 0.D. Pipe Main Steam Isolation Check Valve" to determine if the Instruction Manual adaquately describe the maintenance requirements.

d.

Interviewed AM Field Service Engineer for clearification of his Field Service Trip Report.

4.

Findings The AM field service engineer was at the con Ed Indian Point Nuclear Station, Unit 2, on January 14 and 15,1980 performing a service call on the main steam isolation valves (MS-1, 21, 22, 23 and 24).

The field service engineer stated while performing the service of these valves he place his weight (approximately 150 pounds) on the two (2) i l

~

-~

13 150 pound counter weight on one of the main steam isolation check valves and the 550 pound disc did not move.

Further investigation revealed all four (4) isolation check valves were stuck in the open position; therefore, he recommended all valves be repacked and checked for freedom of movement in accordance with the AM instruction manual.

Section II " Installation" of the AM instruction manual states in

part,

"... Following installation and before putting pressure on valve, make certain that disc remains seated.

Weights actually should counteract 75 to 80% of the weight of the disc but should never hold valve open. Disc should always be free to seat by its own weight."

Section III " Maintenance," paragraph " Preventive Maintenance" in the AM instruction manual amplifies the degree of freedom required for these isolation check valve by stating in part,

" Care should be taken when repacking the stuffing box or tighten-ing the glands, that the glands are screwed down equally and not cocked or tipped so that a corner of it presses on the valve shaft. The glands are not to be screwed down so tightly that the packing retards the easy movement of the valve shaft.

When any adjustments are made on a gland, it is advisable to cycle the valve two or three times to make sure of smooth operation.

AM does not havg the steam capacity to test the valve packing for 1085 psig @ 600 F; however, after assembly and during leakage test the valves were tested for operability. After the valves were hydrostaticly tested the packing is removed, the valve dryed, new packing inserted into the valve, and the hex nut for tightening the gland are hand tightened, for shipment.

Since these valves have been in service for a number of years and had required repacking and/or gland adjustments to prevent leakage on several occasions it is apparent the licensee did not follow the instruction manual when performing these maintenance operations.

F.xit Intert ew i

At the conclusion of the inspection on May 6, 1980 the inspector met with j

the company's management, identified in paragraph A, for the purpose of informing then as to the results of the inspection.

During this meeting each identified deviation was discussed and the evidence which supported the findings were identified.

~.

14 The company's management acknowledged the findings and supporting evidence as being understood, but had no additional comments.
