SUBJECT: ENFORCEMENT CONFERENCE SUMMARY

(NRC INSPECTION REPORT NO. 50-302/87-41)

This letter refers to the Enforcement Conference held at our request on

February 22, 1988. This meeting concerned activities authorized for your

Crystal River facility.

The issues discussed at th's conference related to diesel generator loading and

cooling water temperatures. A sumary, list of attendees, and a' copy of your

handout are. enclosed. We are continuing our review of these issues to

determine the appropriate enforcement action.

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 letter and its enclosures

will be placed in the NRC Public Document Room.

Should you have any questions concerning this matter, please contact us.

Sincerely,

ENCLOSURE 1

ENFORCEMENT CONFERENCE SUMMARY

An Enforcement Conference was held on February 22, 1988, to discuss the

potential violation described in Inspection Report No. 50-302/87-41.

The licensee did not provide any information during the enforcement conference

which would require correction to the information in the inspection report.

The licensee did, however, point out that he reported to the NRC the fact that

the 30-minute rating of the diesel generators had been exceeded during previous

18-month surveillance test and the vendor recommended special inspections had

not been performed. This information was verbally reported on September 14,

1987, and the licensee was give verbal approval to continue operation until

September 19, 1987, when the outage began.

While addressing the root cause and corrective actions for the proposed

violation, the licensee stated that he will expedite his Configuration

Management Program. The licensee proposed extensive corrective actions

directed at the broad scope of potential design errors through the Configura-

tion Management Program. The licensee suggested a meeting, at a date to be

detennined later, to discuss the details of the program, and the handling

of problems that may come to light as a result of the review process.

The adequacy of the ultimate heat sink temperature was discussed even though

this was not within the scope of Inspection Report No. 50-302/87-41. Refer to

Enclosure 3 for details.

The licensee stated that his best estimate for the load on Diesel Generator A

is 3112kw. This value was determined by calculation and testing and,

represents a blending of the two methods. A meeting is scheduled for March to

discuss options for reducing the load below the 30-minute rating range of

3001-3300kw.
