SINNS No.: 6820 OMB No.: 3150-0011 IEB 83-05 UNITED STATES NUCLEAR REGULATORY COMMISSION OFFICE OF INSPECTION AND ENFORCEMENT WASHINGTON, D. C. 20555 May 13, 1983 IE BULLETIN NO. 83-05: ASME NUCLEAR CODE PUMPS AND SPARE PARTS MANUFACTURED BY THE HAYWARD TYLER PUMP COMPANY Addressees: For action: Those utilities with nuclear power reactor facilities holding an operating license (OL) or construction permit (CP) that (1) use or plan to use ASME Nuclear Code pumps manufactured by Hayward Tyler Pump Company (HTPC), or (2) use or plan to use spare parts provided by HTPC in ASME Code pumps manufactured by HTPC or other companies. The period of concern is pumps or parts manufactured by HTPC during the period 1977 through 1981. For information only: All other nuclear power reactor licensees and CP holders. Purpose: The purpose of this bulletin is (1) to apprise the above addressees that NRC's investigation of allegations resulted in NRC findings that HTPC failed to effectively implement its QA program, and (2) to request that the affected addressees take action to resolve this issue. Description of Circumstances: On October 30, 1981 the NRC received an allegation from a newspaper journalist claiming that HTPC located in Burlington, Vermont had manufactured certain safety-related pumps which were found to be defective and had shipped them to various domestic and foreign nuclear plants. On November 2, 1981 the journalist clarified that four individuals had made allegations concerning HTPC and, at that time, he stated he would encourage the allegers to forward specific information to the attention of the NRC. On December 11, 1981 affidavits confirming the allegations and signed by the four former employees of HTPC were forwarded to the NRC. . IEB 83-05 May 13, 1983 Page 2 of 5 As a result of these allegations, the NRC initiated an investigation into the matter on January 4, 1982. This investigation/inspection of HTPC was conducted during the period of January 4, 1982 - August 26, 1982. The results of this investigation/inspection are discussed in NRC Report No. 99900345/82-04, "Investigation/Inspection of Allegations Involving the Hayward Tyler Pump Company, Burlington, Vermont, November 1982."
In view of the findings resulting from the investigation/inspection, the investigation team has recommended (in the Report) that licensees who use, or plan to use, ASME Code pumps manufactured by HTPC during the period 1977 to 1981, conduct certain performance tests to assure that requirements of 10 CFR 50 have been satisfied. The team members believe that satisfactory performance of these pump tests are necessary to verify that the pumps in question will operate as intended. During the investigation, HTPC in letters dated March 10, 1982 and July 27, 1982 (Exhibits 6 and 6a of the Report) proposed certain performance tests (termed "expanded commissioning tests" by HTPC), which in its view, will provide added assurance of pump reliability. The HTPC response (dated January 26, 1983) to the team recommendations documented in Report No. 99900345/82-04 did not result in any change to the HTPC recommendations of March and July 1982. This office concurs with the inspection team recommendation that pump performance tests are necessary to provide assurance that the pumps will perform their intended safety function. The HTPC proposed performance tests supplemented by an endurance run of some reasonable period of time is considered an adequate test to address the concerns raised by the investigation/inspection report. Each licensee or CP holder planning to use a pump manufactured by HTPC is being asked to conduct a pump performance/endurance test. This test is the minimum action deemed necessary by the NRC to ensure pump reliability considering the uncertainties identified in the investigation/inspection report. A list of those facilities using Hayward Tyler pumps that have been identified to the NRC is given in Attachment 1. The pump service and number of pumps are also included in Attachment 1. The performance tests recommended by HTPC are provided in Attachment 2. Each licensee or CP holder planning to use spare parts for ASME Code pumps is being asked to address the HTPC recommendations on installation of replacement parts and to conduct a pump performance/endurance test, if necessary, to ensure reliability of the pumps. The additional recommendations by HTPC for installation of replacement parts are provided in Attachment 3. Affected licensees or holders of construction permits requiring this report should a request a copy from the appropriate NRC Regional Administrator. Copies of pertinent information about the HTPC response to the NRC enforcement letter letter dated December 22, 1982 will also be provided. . IEB 83-05 May 13, 1983 Page 3 of 5 Actions To Be Taken by Nuclear Power Reactor Facilities Holding an Operating License (OL) or Construction Permit (CP) 1. Those holders of operating licenses and construction permits that use or plan to use ASME Code pumps important to safety manufactured by HTPC are to take the following actions: a. Review all ASME Code pumps manufactured by HTPC and provide a list of affected pumps and their service application. A list of affected pumps that was developed by review of HTPC records is given in Attachment 1. b. Provide a summary of the inservice test requirements or plans to develop inservice test requirements for each affected pump at your facility. c. Conduct a pump performance test to assure that each pump will perform its intended safety function. As a minimum, this test should contain the criteria given in Attachment 2. In addition to the criteria presented in Attachment 2, it should be demonstrated that the pumps operated satisfactorily for a minimum duration of 48 hours without maintenance or repair. Provide the results of the pump tests or, if testing has not been completed at the time of the bulletin response, provide a description of the test plan. Nuclear reactor facility licensees with pump's that are currently in service can provide,the results of previous tests and/or operating experience that provide equivalent data and results in lieu of performing the above tests. d. Provide the results of the required ASME Code system hydrostatic pressure test that was performed at your facility when the pump was tested and any corrective actions taken as a result of the test. If the system hydrostatic test has not been completed, provide the test plans. 2. Those holders of operating licenses and construction permits that use or plan to use spare parts manufactured by HTPC in Code pumps important to safety are to take the following actions: a. Review the HTPC recommendations on replacement parts given in Attachment 3. For those facilities that have not yet installed the replacement parts, implement the recommendations given in Attachment 3 in your procedures for pump assembly or provide the basis for any deviations. For those facilities with parts already installed, describe any deviations from the recommendations given in Attachment 3 and discuss their significance. b. Provide the information requested in Item 1b. . IEB 83-05 May 13, 1983 Page 4 of 5 c. Conduct a pump performance test as specified in Item 1c unless it can be demonstrated that the spare part in question will not affect any parameters that are measured or function demonstrated by the test. d. For spare parts that form part of the ASME Code pressure boundary, perform the actions required in Item 1d. 3. Nuclear reactor facilities holding an operating license or a construction permit, are to submit a report describing the results of the actions taken or planned for Items 1 and 2 within 90 days of receipt of this Bulletin. 4.
