Follow-up of Reported Deficiency of Sheared Pin on Valve Disc 1.
Background Information NRC, RII, received a Reportable Occurrence Report BFRO-50-259/7837, from the Tennessee Valley Authority dated December 29, 1978 reporting that during a valve maintenance inspection, a 10 inch, 150 pound, carbon steel, swing check valve (1-71-580) was found in the open position due to the pin shearing from the valve disc.
The report referenced a previous occurrance as being 50-260/786, however, the report states that this was the first failure of its nature, and was considered by TVA to be random in nature.
l
6 On October 18, 1979, an inspection was conducted at Velan Engineering Ltd. The purpose of the inspection included the development of additional information concerning reported failure of the sheared disc pin. The results of this inspection are described in Report Number 99900061/79-02, Item C,2.
The vendor's evaluation concerning the possible cause of the failure was not available at the time of the inspection.
2.
Objective The objective of this area of the inspection was to review the vendor's evaluation of the cause, and corrective action proposed or taken by the vendor.
l 3.
Method of Accomplishment The objective of the inspection was accomplished by review of the following documents.
TVA's letter to Velan Valve Corp. Plattsburgh, New York dated a.
December 5, 1979 subject " Browns Ferry Nuclear Plant, 10 inch Cast Carbon Steel Swing Check Valve, Contract 66C60-90744, NIM-1."; notifying VEL that Browns Ferry personnel had found sheared disc pins in several 10 inch swing check valves, and requesting certain information concerning the casting, machining and weights of the valves in question.
b.
VEL's Memo, John Farrell to A. K. Velan, dated December 12, 1979, Subject " Disc Pin Failure - TVA."; informing the President of VEL, of TVA's finding' and requests for certain information.
c.
VEL's letter to TVA dated December 14, 1979; Subject "10 inch Cast Carbon Steel Swing Check-Valve Drawing P-33160-25."; in response to TVA's letter of December 5,1979, and transmitting the information requested by TVA, and in return requesting certain information from.TVA, including a request for pieces of the failed parts for metallurgical examination.
d.
VEL's letter to TVA dated February 15,198C, Subject " 10 inch Cast Carbon Steel Swing Check-Velan Drawing P-33160-25."; in-forming TVA that they had received no response to their letter of December 15, 1979, and requesting TVA's cooperation in obenining the information and pieces of the failed parts requested.
l l
7 4.
Findings There appears to be certain inconsistencies in TVA's report to a.
NRC RII, dated December 29, 1978, and its letter to VEL, dated December 5,1979.
In TVA's report to NRC they state that the sheared disc pin is the first failure of its kind, and is consi-dered to be random in nature.
However, a year later, in its letter to VEL, dated December 5, 1979; TVA states that its Brown Ferry personnel have identified several 10 inch swing check valves with sheared disc pins, which if accurate implies that generic possibilities exist, and may require the Vendor to report the failures in compliance with 10 CFR 21.
b.
The vendor has requested additional information from TVA to assist in his determination of the cause of the failure, and corrective action.
This information had not been received at the time of this inspection.
c.
The vendor's evaluation of the cause and corrective action will be carried as a follow-up item ;q be confirmed during a sub-sequent inspection.
E.
Exit Interview At the conclusion of the inspection on June 6, 1980 the inspector met the company's management, identified in paragraph A, for the purpose of informing them as to the results of the inspection.
During this meeting management was informed no deviations or unresolved items were identified.
The company's management acknowledged the inspector's statement and had no additional comments.
