SUBJECT: MANAGEMENT MEETING

Dear Mr. Maynard:

This refers to the meeting conducted at the Wolf Creek Generating Station site on

August 29,1997. This meeting related to updating the information provided in the Wolf

Creek Nuclear Operating Corporation's letter of June 20,1997. This letter provided a

response to NRC Systematic Assessment of Licensee Performance (SALP) report (NRC-

Inspection Repurt 50 482/97 99). The meeting provided a useful forum for discussions of

your efforts to improve performance in the areas of corrective action and human

performance, as well as in the four SALP functional areas.

I

-In accordance with Section 2,790 of the NRC's ' Rules of Practice," Part 2, Title 10, Code

-

of Federal Regulations, a copy of this lettor will be placed in the NRC's Public Document

Room.

Should you have any questions concerning this matter, we will be pleased to discuss them

with you,

' Sincerely,

- Root causes performed by a smaller group of trained

individuals who receive direct feedback from CARB

- CARB review challenges the manager and evaluator

" Clear link between problem, cause and corrective actions

Considered other causes

Generic implications

- Fix and Trend

Twice the number of PIRs from four years ago

Need to ensure resources are on the correct priorities

Fix the immediate problem and reserve analysis until more data is

obtained (i.e., trending)

- Common Cause Analysis

First common cause completed 8/97: improvement needed in PIR

'

coding and enhancements needed in capture of information in

database

Reaffirmed previous assessments and the results line up with

initiatives already in place

- PIR Review

1

Look for recurring issues requiring Level I and 11 PIRs

Determine problem scope and identify ineffective corrective actions

.

- PIR Coordinator topics

'

" Specific topics being monitored by PIR Coordinators to meet group's

needs (e.g., clearance order issues, rad worker practices)
