Weakness (445/9524 01: 446/9524 01)

Weakness:

Failure of the Operations Support Center (OSC) to implement repair priorities established by the Technical Support Center (TSC).

Communication and control of repair priorities at the OSC were not fully effective in at least one instance. Two major priorities were identified in facility repair to facilitate regaining control of the scenario event: (1) the top priority was to restore the emergency core cooling system (ECCS) and (2) the second major priority was the repair of the diesel generator.

Shortly after a 9:36am priorities briefing at the TSC, the number one priority was reported to the OSC as " Restore ECCS". Repair of the Residual Heat Removal Pump 1 02 breaker was communicated as the lead sub element of that top priority even though " Restore ECCS" was listed as the first priority on the OSC priorities board, no sub elements were listed until 11:48am.

Due to an apparent miscommunication between the OSC and the-staging area supervisor, the need to repair the pump breaker before the diesel generator was not communicated. As a result, work was performed on-l the diesel generator instead'of restoring ECCS. This delayed restoration of the ECCS for more than an hour.

Response to Weakness (445/9524 01: 446/9524 01)

TU Electric has reviewed the emergency exercise response and the above described weakness. Two emergency response activities were identified for improvement. The activities are related to obtaining (1) clear, specific communication of priorities between the TSC and OSC: and (2) effective communication and control between the OSC and the staging area supervisor.

i The issue of obtaining clear and specific communication of repair priorities between the TSC/OSC will be addressed by providing training to the OSC Maintenance /ERDC Supervisors in order to ensure that specific work items (and any important subtasks), instead of general issues, are tracked on the OSC priority status board.

The issue of coordination of work priorities between OSC and staging area personnel is being addressed by incorporating the use of the newly formed maintenance PROMPT Team. The PROMPT Team has been recently implemented at CPSES on a daily basis for normal operations and occupies the OSC and new staging area directly adjacent to the OSC.

Prompt Team membes are being trained for emergency response positions in the OSC and ERDC Teams. Use of i

this resource should provide numerous benefits to include;

- =

A Attachment to TXX 96038 (1) faster response to priorities since many of the OSC assigned personnel work daily in that location, (2) simpler coordination as the staging area is now directly adjacent to the OSC and (3) better and more effective communications because PROMF) Team members will be accustomed to working with each other handling normal daily maintenance activities.

TV Electric will have completed actions as identified in this response by February 21, 1996. Corrective action documentation will be available for

)

review by the NRC during subsequent follow up inspections.
