10 CFR 50.59 (b)(1) states, in part, that the licensee shall maintain records of changes to the facility as described in the safety analysis report that include a written safety evaluation, which provides the basis for the determination that the change does not involve an unreviewed safety question.

Contrary to the above, as of April 10, 1998, the motor leads for a containment fan cooler unit (CFCU 2-5) were rated to 600 volts; however, no safety evaluation had been performed for the defacto change to the facilityas required by 10 CFR 50.59(b)1 for the determination that the change did not involve an unreviewed safety question.
