Response to Inspection Report No. 50-29/88-02
Dear Sir:
Reference (b) documents a safety assessment team inspection conducted by
Mr. N. Blumberg on January 10 through 15, 1988 at the Yankee Nuclear Power
Station, Rowe, Massachusetts and the Yankee Atomic Electric Company,
Framingham, Massachusetts. The report identified an activity that was not
conducted in full compliance with NRC requirements.
This activity was
identified as a Severity Level IV violation.
In accordance with 10CFR2.201,
we hereby submit the following information:
.
Violation
100FR50, Appendix B, Criterion VII, "Control of Purchased Material,
Equipment, and Services," the Yankee Operational Quality Assurance Program
Manual, and Administrative Procedure AP-0211. "Material & Service Procurement
Program" require that measures be taken to assure that purchased material
I
conforms to procurement documents and that records of such conformance be
.
l
retained. Additionally, 10CFR50, Appendix B, Criterion III, "Design Control"
and the Yankee Operational Quality Assurance Program Manual require that
measures be established to assure that regulatory requirements and the design
l
bases are translated into specifications, drawings, procedures, and
instructions.
Contrary to the above, on January 13, 1988 during repair of a
safety-related vapor containment high pressure alarm, fuses in the alarm
bistable were replaced "in ktnd" with comercial grade fuses which were not
purchased in conformance to procurement documents.
In addition, although the
fuses were replaced "in kind " the exact fuse size required for the vapor
containment alarm was not translated into specifications, drawings,
procedures, or instructions.

Response
We concur with the Notice of Violation as described above and in
Reference (b).
I.
Event Description
--
On January 13, 1988, Maintenance Request MR 88-89 was initiated for
the Instrumentation and Control Department to troubleshoot and
repair a failed vapor container pressure channel, VC-PI-243.
The
failure was determined to be a blown fuse in the alarming circuit.
The fuse was replaced "in kind" from the stock in the Control Room.
This stock cf fuses was not purchased under a program to ensure that
commercial grade fuses possess the required measures of assurance to
allow their use in safety-related applications.
II.
Corrective Steps Which Have Been Taken and Results Achieved
A program has been established for the dedication of commercial
grade fuses to be used in Quality Assurance (QA) applications.
The
program consists of purchasing the fuses in accordance with plant
Procedure AP-0212. "Control of Purchased Material Equipment, and
Services." Plant maintenance personnel have been instructed in this
program.
III. Corrective Steps Which Will Be Taken To Avoid Further Violations
Yankee intends to perform the following steps:
A.
0A Fuse Documcntation Program
We plan to implement a fuse documentation program. The program
will consist of preparing a work instruction to identify the
scope of fuses requiring QA, standardizing fuse size
guidelines, performing a walkdown of plant systems to document
,
fuse location and sizes, and updating the applicable plant
drawings.
B.
Utilization of Commercial Grade Items
We intend to modify Yankee procedures to include specific
guidance on the acceptance of all commercial grade equipment
for use in QA applications. This guidance will be developed
using EPRI NP-5652 "Guldance for the Utilisation of Commercial
.
Grade Items in Nuclear Safety-Related Applications (NCIG-07)."
It will include a requirement to determine the critical
characteristics and the means by which verifiestie. of
acceptability will be performed when any conmercial grade item
is used in a QA application.

IV.
The Date When Full Compliance Will Be Achieved
The QA Fuse Documentation Program will begin this summer to support
initial system walkdowns during our Cycle 19-20 refueling outage
scheduled late this year. We intend to complete our system
walkdowns during our Cycle 20-21 refueling outage (Summer 1990) with
a final verification walkdown, if necessary, during the Cycle 21-22
refueling outage (Spring 1992).
The modification to the Yankee procedures to include specific
guidance on the acceptance of all comercial grade equipment for use
in QA applications will be completed by November 1, 1988.
Additionally, we were requested in Reference (b) to respond to four
questions about our main steam line pressure switches and three identified
weaknesses. These items will be addressed in a separate letter by
June 30, 1988. However, as an update to your report, Yankee submitted a
10CFR21 Report and a revision to LER 50-29/87-15 on the main steam line
pressure switches on April 26, 1988 Reference (c) and (d).
If you have any questions or desire additional information, riease
contact us.
