SUBJECT'RC INSPECT(ON REPORT 50-315/99003(DRS); 50-316/99003(DRS)

Dear Mr. Powers:

On March 26, 1999, the NRC completed a special inspection conducted at your Buchanan

Michigan Corporate facility. This inspection was an examination of activities under your license

as they relate to your implementation of the Expanded System Readiness

Review (ESRR)

program at your D. C. Cook Units 1 and 2 reactor facilities. The NRC understands that these

reviews are intended to identify design and materiel condition issues that willrequire resolution

before restart to provide assurance

that safety-related plant systems fulfilltheir design basis

safety functions.'ffective implementation of the ESRR process willaddress portions of Case

Specific Checklist Items No. 3, "Programmatic Breakdown in the Maintenance of the Design

Basis," and No. 13, "Systems and Containment Readiness Assessment," that were established

through the NRC's Manual Chapter 0350, "Staff Guidelines for Restart Approval." The NRC will

continue to monitor and assess

the effectiveness of the problem identification phase of your

system readiness evaluations.

The enclosed report documents the results of this inspection.

Areas examined during the inspection are identified in the report. Within these areas, the

inspection consisted of a selective examination of procedures and representative

records, and

interviews with personnel

~ At the conclusion of the inspection, the findings were discussed with

you and members of your staff.

Overall, the initial implementation of the ESRR process was effective. Significant programmatic

issues and technical concerns have been identified by the ESRR teams, including cable

separation concern, seismic mounting deficiencies, and spray header obstructions.

Management has maintained active oversight of the ESRR process through the System

Readiness

Review Board. This oversight function has addressed

the technical rigor and

consistency of the individual ESRR team products.

Several system walkdowns by the ESRR teams were observed by NRC staff to have identified

design and configuration deficiencies and were effective. Most ESSR teams performed

walkdowns using comprehensive checklists to verify design parameters;

however, we observed

specific walkdowns that initiallyappeared to focus more on materiel conditions and did not verify

certain design parameters.

The specific walkdown weaknesses

were subsequently addressed

by your staff.

Based on the large number of condition reports being initiated, the threshold for identifying and

documenting problems appeared conservatively low. Some problems were noted where

condition report information was either incorrect or missing in the new computerized database

'nd

where the condition reports had limited or incorrect descriptions of the issue or did not

consider design requirements.

While we recognize that the electronic corrective action program

(ECAP) is.early in its implementation, these issues represent a continuing challenge in the

proper categorization and resolution of the problems identified by the ESRR process, and

warrant continuing management oversight to assure effective ECAP implementation.

In accordance with 10 CFR 2.790 of the NRC'S "Rules of Practice," a copy of this letter, the

enclosure, and your response to this letter, ifyou choose to provide one, will be placed in the

NRC Public Document Room.

We willgladly discuss any questions you have concerning this inspection.

Sincerely,
