Ys ni DUKE POWER COMPANY CATAWBA NUCLEAR STATION JViolations:
~1.
Technical Specification (TS) 3.0.4 prohibits entry into an Operational
- Mode unless the~ condition for the Limiting Conditions-for Operations are met.without reliance on provisions contained in the Action requirements.
TS 3.6.5.3 requires' ice condenser inlet doors.be closed and operable.
Contrary to the.above, fice condenser inlet doors were blocked closed between December:31,,1984 1following Operational Modes were entered:and January 9, 1985 and therefore, Mode 4 on December 31, 1984, Mode
- 3 on January 2,.1985.and Mode 2 on January 7, 1985,
- 2.. TS '6.8.1 requires written procedures be established and implemented for safety-related systems and components. OP/1/A/6100/01, Controlling
-Procedure for Unit Startup, requires verification that the blocks on the
-ice condenser' lower inlet. doors are removed.
Station Directive 4.2.2, Section 3.1.1,. implements NUREG 0737, Item I.C.6 as referenced in'FSAR Table
- 1.9-1, states.that Independent Verification applies to. removal from and return to operability of all systems or components that effect safety-related functions.
Contrary to the above, OP/1A/6100/01
~
was erroneously completed and indicated that the ice condenser inlet door blocks had been removed when in fact they
-were still installed until January 9, 1985.
Additionally,- independent iverification was not assured and consequently not performed'for' the removal of the door: blocks.
. Response:.
- 1., Duke Power admits the violations.
2.
MiscommuniEation between personnel. created the impression that the ice condenser door blocks had beenLremoved, when in fact the blocks were
'still'in place. This resulted in the unit changing. modes while the limiting conditions-for' operations for technical specification 3.6.5.3 were not being met.
13.
- The door blocking devices were removed.
All. Unit One door blocking devices have been-painted fluorescent orange and will be sequentially numbered
-(1 through 24).
This is to ensure that the blocking devices will be accountable and highly visible when installed. 'A procedure has been
. developed'and implemented to ensure that all mode related requirements
~
- under the. responsibility of the group responsible for unblocking the -
. doors, have been satisfied prior to entering each mode of operation.
Also:a procedure has been implemented specifically for installation and removal of' the door blocking devices. This procedure requires that the installation and removal-be independently verified. Also, all appropriate personnel,as designated by. the Station Manager, have reviewed the methods used to assure completion of required work pertaining to

.4.'All Unit Two door blocking devices will be painted fluorescent green
.and sequentially numbered. This' action and those actions outlined in (3)'will avoid further violations.
