4 This report contains the highlights of the Fort St. Vrain, Unit No. 1, activities operated under the provisions of the Nuclear Regulatory Commission Operating License No. OPR-34. The report for the monthly partial scram / maximum temperature reports for control red drive and orificing assemblies is not included this month because the reactor was not in operation.

This report is for the month of August, 1988, 1.0 NARRATIVE

SUMMARY

OF OPERATING EXPERIENCE AND MAJOR SAFETY RELATED MAINTENANCE The reactor remained shutdown the entire month of August, 1988, for helium circulater bolt replacement.

On August 16, 1988, Public Service Company of Colorado notified the NRC of a change in the CONTEMPT-G comouter program utilized in developing the Fort St. Vrain E.O. temperature profiles. This j

change caused the CONTEMPT-G program to calculate lower peak building temperatures for certain small line break scenarios.

This event will be investigated and reported to tne Nuclear Regulatory Commission in Licensee Event Report 88-012.

On August 29, 1988, at 1745 hours0.0202 days <br />0.485 hours <br />0.00289 weeks <br />6.639725e-4 months <br />, while preparing "C" helium circulator for bolt replacement, five personnel received minor contamination on their hands and feet when helium and water sprayed out of the circulator interspace. The personnel and the area were decontaminated with soap and water. Calculated whole body costs were determined to be negligible.

During this month, bolts in Loop I helium circulators were replaced and the loop was returned to service.

Bolts in Loop II helium circulators will be replaced during the month of Septemcer, 1988.

The 1996 estimated date is based on the understanding that spent fuel discharged during the term of the Agreements will be stored by DOE at the Idaho Chemical Processing Plant.

estimated that the eighth fuel segment will be discharged in 1996.
