Quality Assurance Plans and Procedures for Extended Shutdown
The RIII inspector inquired if an overall QA plan and implementing
procedures had been developed for this extended shutdown. The
licensee stated that they had not yet developed a plan or procedures
for these activities but that it was under consideration. The
inspector inquired if quality related records of the piping contractor
had been turned over to Commonwealth Edison Company (CECO) since a
large number of the people have left the site.
(Construction workers
on site on September 13, 1979 - 1750, September 17, 1979 - 46L,
September 21, 1979 - 342 people). The licensee stated that the
piping contractor had not turned over any of these records as yet.
When asked if any of the contractors had turned over quality related
records, the licensee stated that the electrical contractor,
L. K. Comstock and Company, Inc., had turned over a portion of their
quality related records.
The document that was used for this turnover, dated September 17,
1979, was reviewed by the RIII inspector.
Subject:
L. K. Comstock
and Company, Inc. and E. C. Ernst, Documentation.
The cover letter
reads as follows, "The attached inventory of L. K. Comstock and
Company, Inc. and E. C. Ernst documentation lists documents turned
over to Commonwealth Edison Company; except for drawings and equipment
storage surveillances." It was prepared and accepted by a Quality
Assurance Engineer for CECO and was accepted by the Quality Assurance
and Quality Control Manager for L. K. Comstock.
A handwritten note
on the cover page to the inventory stated, "This documentation is to
be kept in locked file cabinets maintained in the L. K. Comstock
Office Building." The RIII inspector did a random verification of
some of the documents in this inventory.
Results of this verification
indicated that not all of the documentation listed in September 17,
1979, was located in the file cabinets maintained in the L. K. Comstock
Office Building. Seven documents listed on the inventory had been
turned over to the Station Construction Department after the completion
of the inventory and without knowledge of the quality assurance
department.
In addition, at least four other documents were not
located in the file cabinets, but were in the general vicinity,
although they were listed on the inventory. This lack of control of
these documents further indicates that procedures are needed for the
control of these activities.

This failure to have plans and procetires to control these safety
related activities is an item of noncompliance with 10 CFR 50,
Appendix B, Criterion V.
(456/79-12-01; 457/79-12-01)
2.
Storage of Equipment
The RIII inspectors took an extensive tour of the site to observe
storage of equipment in place.
A problem was identifi:J during this
,
tour in that the storage of the reactor coolant pump motors was
-
inadequate.
Several motors did not have their motor winding heaters
energized and they had not been rotated on a weekly basis as required
by the manufacturer's instructions. These problems were corrected
in a timely manner by the licensee.
No items of noncompliance or deviations were identified.
3.
Site Staffing Considerations
The ultimate size of the site staff during the extended shutdown has
not been clearly established. NRC is concerned relative to the
ad2quacy of the size of the surveillance staff, and will pursue this
issue during subsequent inspection. This matter is unresolved.
(456/79-12-02; 457/79-12-02)
No items of noncompliance or deviations were identified.

Extended Construction Delay - Review of Quality Assurance Implementing
Procedures
The inspector reviewed a general procedure, " Commonwealth Edison
Company - Phillips, Getchow Company Quality Assurance Interface for
Requisitioning, Purchasing and Receiving Material", BM-101, Revision 2,
dated April 18, 1979. The stated purpose of the procedure was to
clarify responsibilities for the purchase, receipt and storage of
ASME,Section III materials, parts, components, and the control of
the associated documentation as required by Section III.
The licensee was informed that the lack of such an approved QA
Program was considered to be an element of noncompliance as identified
in Section I of this report.
2.
Extended Construction Delay - Observation of Work and Work Activities
The inspector reviewed the storage of Category I heat exchangers and
compared storage conditions with those recommended by y in their
Instruction Manual for Auxiliary Heat Exchanges.
In addition, the
storage recommendations were revieved for the steam generators. The
licensee stated QA Procedures were being reviewed and revised to
meet manufacturer's recommendations and owner's requirements.
The
licensee agreed to document these instances where manufacturer's
recommendations were not followed.
In general, storage condition for the heat exchangers, met y recommenda-
tions. The majority of the heat exchangers have been mounted on
pe rmanent foundations and piping connections completed. The heat
exchangers observed by the inspector are listed below.
The licensee stated that present plans include closing the turbine
building and temporary openings in the containment and auxiliary
buildings prior to cold weather.
The heating boiler is being installed
and should be available to supply heat for the turbine and auxiliary
buildings.
Electric heaters are to be installed in the containment
buildings to maintain temperatures of 40 F or higher.
The Category I Heat Exchangers were listed in the y Instruction
Manual Auxiliary Heat Exchangers. This manual included nine general
instructions with "Special Instructions" for specific heat exchangers.
