ENCLOSURE 1

NOTICE OF VIOLATION

.

Duke Power Company Docket Nos. 50-369 and 50-370

McGuire Nuclear Station License Nos. NPF-9 and NPF-17

The following violations were identified during an inspection conducted on

February 7 - July 3,1985. The Severity Levels were assigned in accordance with

the NRC Enforcement Policy (10 CFR Part 2,~ Appendix C).

A. Technical Specification (TS) 3.8.2.1 requires that all four DC sources be

operable in Modes 1, 2, 3 and 4.

TS 4.8.2.1.2b states that once per 92 days each 125-volt battery connected

cell demonstrate that the float voltage is greater than or equal to 2.13

volts. TS 4.8.2.1.2a requires the float voltage be checked for each pilot

cell each seven' days.

TS 4.8.2.1.2d states that each 18 months each 125-volt battery bank be

demonstrated operable by verifying that it will supply a dummy load of at

least 440 amperes for 60 minutes.

Contrary to the above:

1. Contrary to TS 3.8.2.1 and TS 4.8.2.1.2b, battery EVCA was technically

inoperable from May 29, 1982 until February 5, 1985 because the actual

battery float voltage was not monitored for cells 29 and 45. The

apparent surveillance discrepancies were identified on February 1, 1985

and corrective action on battery EVCA was not initiated until February 5,

1985.

2. Contrary to TS 3.8.2.1 and TS 4.8.2.1.2d, on February 7, 1985, all four

Vital DC sources were found to be technically inoperable because

surveillance testing performed failed to demonstrate system operability

in that the March and April 1984 service discharge tests for batteries

EVCA, EVCB, EVCC and EVCD were not performed at the current and time

specified by TS 4.8.2;1.2d. ~

This is a Severity Level IV violation (Supplement I).

B. Technical Specification 6.8.1 requires that procedures be established,

implemented and maintained covering the operation and maintenance of

safety related equipment.

Installation drawing MCM 1350.01-1, Rev. A, dated March 12, 1976, specifies

a minimum clearance of one eighth inch between the end cells and the battery

rack.

Duke Power Company 2 Docket Nos. 50-369 and 50-370

McGuire Nuclear Station License Nos. NPF-9 and NPF-17

Contrary to the above, procedures related to battery surveillance and

maintenance were inadequate in th't:

1. Instructions / guidance relevant to monitoring and duration of single

cell charging were not provided resulting in the battery being changed

at a voltage higher than recommended by the Vendor for a period of two

years.

2. Procedure IP-0-A-3061-01, 125 Volt Vital Battery Weekly / Monthly

Inspection and Prevention Maintenance, provided inadequate guidance

which allowed the inclusion of an unattached cell in battery EVCA six-

cells average temperature calculation on February 23, 1984 and

May 19, 1984.

3. Procedure IP-0-A-3061-01 was not followed on January 17, 1985, when the

temperature variance of the six cells varied by 9F, exceeding the SF

acceptance criteria of the procedure, and corrective action was not

taken. Additionally, water was added to battery EVCA and an equalizing

charge was not performed as specified.

4. Procedure IP-0-A-3061-18, Installation and Removal of Jumpers on

Battery Cells, was inadequate in that post-modification testing of the

newly configured battery was not specified. Additionally, the proce-

dure referred to Drawing MC 1705-01 for technical justification for

jumper installation. Drawing MC 1705-01 had been revised in July 1984

and was no longer applicable.

5. Batteries were installed and/or maintained such that end cells were

pressing against the battery rack end plate and did not have the

1/8-inch clearance specified by MCM 1350.01-1.

This is a Severity Level IV violation (Supplement I)'.

C. 10 CFR 50.59 requires written safety evaluations of changes in the facility

as described in the Safety Analysis Report which provides the bases for the

determination that the change does not involve an unreviewed safety

question.

Contrary to the above, the written safety evaluation performed for Operation

of Single Cell Battery Charger, that was employed for attaching single cell

chargers to cells 29 and 45, was deficient in that it did not include the

bases for seismic considerations, maintaining voltage at higher potential

than recommended by the vendor, or maintaining independence of class IE

equipment. This information was necessary to determine whether an

unresolved safety question was present.

This is a Severity Level IV violation (Supplement I).

Pursuant to 10 CFR 2.201, you are required to submit to this office within 30

days of the date of this Notice, a written statement or explanation in reply,

including: (1) admission or denial of the alleged violations; (2) the reasons

for the violations if admitted; (3) the. corrective steps which have been taken

and the re'sults' achieved; (4) corrective steps which will be taken to avoid

further violations; and (5) the date when full compliance will be achieved.
