/ r m ENCLOSURE V0GTLE ELECTRIC GENERATING PLANT - UNIT 1 NRC NOTICE OF VIOLATION 50-424/90-05-01 AND GPC RESPONSE

" Technical Specification 3.4.1.4.2.c, requires that, in Mode 5 with reactor coolant loops not filled, Reactor Makeup Water Storage Tank discharge valves,  !

1-1208-U4-175,176,177, and 183 be closed and secured in position.'

Contrary to the above, on February 26,-1990, with Unit _1 in Mode 5 and RCS level I at 195 feet 5 inches, valve 1-1208-U4-176 was closed but was not mechanically
  • l secured in the closed position. 1 This a Severity Level. IV violation (Supplement I)".

t' RESPONSE TO VIOLATION 50-424/90-05-01 l'

Admission or Denial of the Violation:

~

l

~'

The violation occurred as-stated.

Reason for the Violation:

As stated in the Notice ~of Violation, Technical Specification 3.4.1.4.2.c r requires the- subject valve to be-closed and secured in- position. Similarly, Technical Specification (TS) 3.6.1.7 requires the 24-inch containment purge supply and exhaust isolation. valves .to be closed and sealed' closed. The bases t for TS 3.6.1.7 state that sealed closed isolation. valves are isolation' valves under administrative control to assure they cannot be inadvertently opened. The ,

administrative controls, which constituted the locked valve policy, permitted clearance " hold tags" to be utilized to-secure small vakes which cannot .

feasibly be locked. However, Surveillance Requirement 4.4.1.4.2.2 requires the-subject valve to be secured in position:by mechanical stops. Therefore, the administrative controls were less than adequate which resulted in the violation. '

Corrective Steos Which Have Been Taken and the Results Achieved:-

-The subject valve was wired in the closed position to provide a " mechanical stop" as required by Surveillance Requirement 4.4.1.4.2.2.

Corrective Steos Which Will Be Taken To Avoid Further Violations:-  !

To preclude any further violations, the following corrective steps will be-taken:-

o The-locked valve procedure will be revised by 9-15-90, to eliminate utilization of a " hold tag" on valves that are required by the Technical Specifications to be secured in position.

ENCLOSURE ~(CONTINUED)

V0GTLE ELECTRIC GENERATING PLANT - UNIT 1 NRC NOTICE OF VIOLATION 50-424/90-05-01 AND GPC RESPONSE l-o A review of valves which are required by the Technical Specifications.to, i be secured will. be performed by 9-15-90 to ensure a' locking mechanism is  !

(- in place, t E o Any valve found by this review which is )resently secured by. hold tags-  !

and is required to be secured by the Tecinical Specifications will be.

provided with en appropriate locking mechanism.. This action will be .;

completed by- 9-15-90.

Date When Full Comoliance Will Be Achieved: [

Full compliance was achieved with- the crimping of a steel cable' through- the -  !

drilled holes in the valve handle'to mechanically secure the subject valve.:

s This was accomplished on February 26, 1990.
