Dear Mr. Dewease:
SUBJECT:
EQUIPMENT QUALIFICATION INSPECTION - WATERFORD STEAM ELECTRIC
STATION,. UNIT 3
This refers to the first round special team inspection to review compliance
with 10 CFR 50.49, of activities authorized by License No. NPF-38, conducted by
Mr. A. R. Johnson and other NRC representatives, onsite during the period of
December 8-12, 1986, and subsequently at the NRC Region IV office until
March 13, 1987, concerning the Waterford Steam Electric Station, Unit 3.
The
team's findings were discussed with members of your staff at the conclusion of
the onsite inspection on December 12, 1986.
Areas examined during the inspection included your implementation of a program
for- establishing and maintaining the qualification of electric equipment within
the scope of 10 CFR 50.49.
In preparation for this inspection, the NRC team
included reviews and evaluations of your implementation of EQ corrective action
commitments identified in Safety Evaluation Reports (SERs) NUREG 0787,
Supplements 5, 8, and 10 (June 1983, December 1984, and March 1985), which were
satisfactorily accepted by the NRC staff at that time with regards to equipment
for which justification for interim operation (JI0s) were provided prior to the
November 30, 1985, deadline.
.
Within these areas, the inspection consisted of the examination of selected
procedures and records, interviews with personnel, and observations by the NRC
inspectors. The inspection findings are documented in the enclosed inspection
report.
'The inspection determined that you have implemented a program to meet the
requirements of 10 CFR 50.49. Seven deficiencies with respect to your program
implementation, involving EQ documentation files and physically installed
configurations of equipment in your plant, are summarized in Appendix A and are
classified as Potential Enforcement / Unresolved Items requiring further action.

All seven Potential Enforcement / Unresolved Items represent failures to fully
establish the qualifications of the following equipment: Borg-Warner motor
operators ITT Barton.763/764 pressure transmitters, Okonite bolted cable
splices to General Electric pump motors, Thomas and Betts blind barrel crimp
cable spl_ ices to Limitorque SMB series motor operators, unidentified internal
wiring in Limitorque SMB series motor operators, and BIW cable assemblies.
Sixteen concerns are classified as Open. Items and a future NRC inspection'will
-
review your actions concerning them.
Your . letter to NRC,, Region IV of February 2,1987, providing additional
information subsequent to the onsite inspection, addressing the. inspection
findings presented in~the exit interview on December 12, 1986, has been
'
reviewed and was considered in preparation and issuance of the enclosad
inspection report.
-Your corrective actions regarding the identified deficiencies in the enclosed
inspection report should not be delayed pending a future NRC Region IV
inspection.
We are available to discuss any questions you have concerning this inspection.-
Sincerely,
Original Signed bkt

APPENDIX A
i
Potential Enforcement / Unresolved Items
= As a result of the special equipment qualification (EQ) inspection of
December 8-12, 1986, the following items have been identified by Region IV as
Potential. Enforcement / Unresolved Items (paragraph references are to the
detailed portions of the inspection report).
1.
Contrary to paragraph (f) of 10 CFR 50.49, the equipment qualification
file '(EQF), electrical equipment qualification documentation
package (EEQD) 42.3, for Borg-Warner motor operator model 39400 installed
in the containment building, did'not adequately establish qualifications
because of failure to demonstrate similarity.between the tested
model 86090 and the installed model 39400. Justification for Interim
Operation (JIO) for.Borg-Warner operators, dated May 16, 1985, required a
station modification to upgrade these operators by November 30, 1985,
i
(paragraph 4.f.(1), ' Item 50-382/8632-01).
2.
Contrary to paragraph (f) of 10 CFR 50.49, the EQF,.EEQD 8.2A for ITT
Barton model 763 and 764 pressure transmitters during the time of the NRC
inspection, did not adequately establish qualification because of failure
to demonstrate qualification for submergence based on DBA/ post DBA
conditions.
(paragraph 4.f.(3), Item 50-382/8632-02).
-
~3.
Contrary to paragraph (f)_of 10 CFR 50.49, the EQF for General Electric
CVC charging pump motors, did not adequately establish qualification
because of failure to demonstrate similarity between the type tested
- nuclear qualified heater connection splices and the installed Okonite
bolted type taped s lices at the Waterford plant-(paragraph 4.h.(2)c,
Item 50-382/8632-03 .
.
4.
Contrary to paragraph (f) and (k) of 10 CFR 50.49, and NUREG 0588,
Category II, paragraph 5, the EQF for Limitorque motor operator,
model.SMB-00, UNID No. EFW-MVAAA-220-A, did not adequately establish
qualification because of-failure to demonstrate similarity between the
tested and installed cable splices. No evidence was contained in the EQF
which could demonstrate qualification of blind barrel crimp splices used
-
in operator EWF-HVAAA-220-A (paragraph 4.f.(4), Item 50-382/8632-04).
,
[
5..
Contrary to paragraphs (f) and (k) of 10 CFR 50.49, and NUREG 0588,
,
Category II, paragraph 5, the EQF, EEQD 3.1, for model SMB series
i
Limitorque motor operators did not adequately establish qualification of
~ internal wiring installed in operators prior to September 1986, in that
wiring was unidentified and there were no test reports to show that the
!
wiring was qualified in accordance with 10 CFR 50.49 (paragraph 4.f.(6),
Item 50-382/8632-05).

6.
Contrary to paragraphs (f) and (k) of 10 CFR 50.49, and NUREG-0588,
Category II, paragraph 1.2.(5), the EQF, EEQD 14.1/52.1, for BIW cable
assemblies (which includes CIR series connectors and flex conduit), did
not adequately establish qualification because it failed to base the
temperature qualification for materials within the connector / cable
assembly on the temperature effects of a MSLB as modified by a thermal lag
analysis (paragraph 4.f.(7)(a)
Item 50-382/8632-06).
7.
Contrary to paragraphs (f) and (k) of 10 CFR 50.49, and NUREG-0588
Category II, paragraph 4(2), the EQF, EEQD 14.1/52.1, for BIW cable
assemblies (which includes CIR series connectors and flex conduit), did
not adequately establish qualification because no replacement schedule had
been established for components susceptible to aging effects that are
,
located in an elevated service temperature environment-
(paragraph 4.f.(7)(b), Item 50-382/8632-07).
