i DUKE POWER COMPANY REPl.Y 'M) A NOTICE OF VIO1ATION 413, 414/90-11-01 10CTR50, Appendix B, Critorion V Instructions. Procedures and Drawings; requires that activities affecting quality be prescribed by documented instructions, procedures, or drawings, appropriate to the circumstances and that these activities can be accomplished in accordance with these instructions, procedures, or drawings. These instructions, procedures, or drawings shall include appropriate quantitative or qualitative acceptance criteria for determining that important activities have been satisfactorily accomplished. Implicit in these requirements are the requisites that these instructions, procedures and drawings be accurate, current, and reflect actual as-built conditions.

Contrary to the above A) The licensee failed to establish documented instructions or procedures to ensure that movable lifting beams / chain hoists were secured in or removed from the ice condenser as specified in the modification package. On April 22, 1990, the beams were found unsecured above the intermediate deck doors in both units.

B) On May 8, 1990, it was determined that plant drawings CN-2705-02.04.01 and CN-2705-02.04.02 did not reflect actual as-built configurations in that they showed that power existed to two breakers 4 in Unit 2 power panels 2KXPA and 2KXPB when they were actually  !

spares.

RESPONSE

)

1. Admission or Denial of Violation Item A. Duke Power admits the violation.

Item B. Duke Power admits the violation. However, this editorial discrepancy would not have caused any problem with proper plant operation.

2. Reasons for Violation if Admitted Itum A. There was a failure by Maintenance personnel to understand the requirement to securely locate the I-Beams / hoists ,

established by the design engineering recommendations. As l a result of this misunderstanding, no formal documentation was developed to control the I-Beam / hoists.

! Item B. When Catawba Unit 2 design. work was started, breakers L'

2KXPA-28 and 2KXPB-27 on Unit 2 were reserved for loads corresponding to the same breakers on. Unit 1. Breaker .i assignments were normally made permanent when the  !

engineering package was developed and the identifying cable

' number and cable size were added to the one line drawing.

This did not occur with these breakers because they were not needed for the remaining design of the plant security ,

,J r system. Since the plant security system documentation is Safeguards Information it was not available to the engineer. ,

U; responsible for the breaker panels.

A 3ecurity review of the Unit 2 one line drawings did not i

, n:co: occause all power requirements for the security ,

system design were satisfied through Unit 1 breaker assignments.

Since the plant went into operation, procedures now require -

that the design for each unit is done independently and ,

breakers are not reserved for future use. This prevents ,

the same kind of discrepancy from occurring again with any i

kind of breaker assignment, The A6, computer generated electrical load list contained 3

,i discrepancies for exactly the same reasons as noted above.

It is a computer tabulation of loads from the one line drawings and is supported by the same reference information.

This editorial discrepancy occurred primarily because it -

was a security related circuit and because of the resulting restrictions in the design process for handling Safeguards Information. Ilowever, an investigation was performed immediately after this discrepancy was identified and all plant breaker assignments feeding the security system on both units were verified to be correct r.d no similar discrepancies were noted. This was an isolated caso due to unique circumstances

• and personnel responsible for the security equipment had proper information on Safeguards Information drawings identifying the actual power sources.

3. Corrective Actions Taken to Avoid Yurther Violations and Results i Achieved Item A. On 4/22/90 the I-Beams /iloists were rolled to the ends cf the ice condenser such that they were not directly above the intermediate deck doors.

,J r

rails to prevent any movement. This was done in both units.. I

[ After securely locating the I-Beams /Holsts on 4/23/90 Catawba Nuclear Station was in full compliance with the design requirements, p'p Item B. .The A6 electrical load list has been revised to identify breakers 2KXPA-28 and 2KXPB-27 as spares.

g A plant inspection was conducted and showed no other ,

l e discrepancies in breaker assignments for security loads. A

. design review of the one line drawings and A6 electrical j load list for the same loads also showed no other discrepancies, j A general overview confirmed that the normal pror.ess of checks and balances for one line drawings and thu A6 ,

electrical load list prevent this type discrepancy from .:'

occurring with non-security loads.

o Duke Power is evaluating optiona zor establishing.more control of information in the A6 electrical load lict. ,

4. Corrective Actions to be Taken to Avoid Yurther Violations t i

Item A. At the conclusion of the Unit 2 E003 which is currently scheduled for September 1, 1990 the I-Beams / Hoists will be

. securely located on the rails as required by Design and documented on Work Request 6229 SWR. (MES)

Standing Work Requests (SWR's) will be written by the Unit 1 EOC5 which is currently scheduled for March 5, 1991.

These SWR's are to ensure the I-Beams / Hoists are securely located on the crane rails in Modes 1-4 and will be added .

to the Mode 4 checklist which is part of Operations Startup procedures OP/1,2/A/6100/01. (MES)

Pi Item B. Editorial corrections will be complete by 9/30/90 to show breakers 2KXPA-28 on drawing CN-2705-02.04-01 and 2KXPB-27 q.1 on drawing CN-2705-02.04-02 as spares. (Projects / Design) i r
