RESPONSE TO NOTICE OF VIOLATION

. INSPECTION REPORT NOS. 50-280/84-36 and 50-281/84-36 VIOLATION Technical ' Spec'ification .(TS). 3.6.B.1 requires that prior to-Texceeding 350 F or 450 psig in the Reactor Coolant System (RCS), one

of the .three auxiliary feedwater (AFW) pumps for the opposite unit shall be'available. In addition, TS 3.6.D requires that the system piping, ' valves, and control board indication required for the operation of the opposite unit AFW pump be available.

. Contrary to - the . above, Unit 2 was operated at full power from September 28, 1984, to October 30, 1984, with the Unit 1 AFW pumps not available to Unit 2 because the motor operated cross-tie valve MOV-FW-260A was closed' and not available (without indication) due to the tagout and opening of its electrical breaker 1H1-211.

This is a Severity Level IV violation (Supplement I) and applies to Unit 2.

RESPONSE ,

(1) ADMISSION OR DENIAL OF THE ALLEGED VIOLATION:

The violation is correct as stated. Operations personnel discovered this condition during a Plant Tagout Review.

(2) REASONS FOR VIOLATION:

The reason for this violation is an error in plant drawings.

-Both tagouts involved were proper with respect to plant drawings, but the drawings were inaccurate with respect to the as-built condition.

(3) CORRECTIVE STEPS WHICH HAVE BEEN TAKEN AND THE RESULTS ACHIEVED:

As described in LER 84-017-dated January 4, 1985, the piping and instrument drawing located in the control room was temporarily changed,on De,cember 4, 1984 to reflect the as-built condition and later permanently revised. An-engineering review.of other station drawings and procedures related to the auxiliary feedwater crosstie was conducted.

-The review identified necessary updates to some electrical drawings. In addition, changes were identified in valve line-up procedures.

e

-(4) - CORRECTIVE STEPS Wii...( VILL BE TAKEN TO AVOID FURTHER

i. ,

VIOLATIONS:

The appropriate' electrical drawings will be updated to reflect as-built conditions and cable tagging will be verified to correct any tagging deficiencies found. The valve lineup procedures will also be updated to reflect unit assignment of the cross-tie M0V's.

(5)- THE DATE'WHEN FULL COMPLIANCE WILL BE ACHIEVED:

Full compliance was achieved on December 4, 1984. The additional actions identified by engineering review will be completed by May 1, 1985.
