IE BULLETIN NO. 83-05: ASME NUCLEAR CODE PUMPS AND SPARE PARTS
MANUFACTURED BY THE HAYWARD TYLER PUMP COMPANY
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.
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.

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
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

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
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.

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. Nuclear reactor facilities holding an operating license, are to
complete the actions requested by Items 1c and 2c, as applicable, prior
to start-up from the outage during which the pump or part is installed
or, if the pump or part is already installed, before startup from the
next refueling outage.
5. Nuclear reactor facilities holding a construction permit, are to
complete the actions requested by Items 1c and 2c, as applicable,
before issuance of the OL.
6. Those holders of construction permits whose construction permits are
suspended, delayed, or cancelled are to take no action unless
reactivation of construction or transfer, sale, or other consignment of
the subject pumps, or spare parts to another nuclear plant site is
contemplated. In such cases, both the NRC and recipient permit holders
or licensees should be notified of the disposition of said pumps or
spare parts to assure that 10 CFR Part 50 requirements will be
satisfied. Recipients of such pumps or paris are to perform the actions
specified in Items 1 and 2, as appropriate, and notify the NRC.
The written report required by Item 3 above shall be submitted to the
appropriate Regional Administrator under oath or affirmation under
provisions of Section 182a, Atomic Energy Act of 1954 as amended. In
addition, the original copy of the cover letters and a copy of the reports
shall be transmitted to the U.S. Nuclear Regulatory Commission, Document
Control Desk, Washington, D.C. 20555 for reproduction and distribution.
