Rochester Gas and Electric is submitting the attached 10CFR Part 21 Evaluation and Notification. The notification concerns a defect in design of two (2) Residual Heat Removal Pumps supplied by Pacific Pump, Inc. of Los Angeles, CA. The defect consist of an interference between the mechanical seal pumping ring and the pump discharge housing.
The defective designed pumping rings were installed in 1969, during the construction phase, as a result of a mechanical seal modi ficati on.                The mechanical seal was suppli ed by Crane Packing Company.                  Due to the date of occurrence,        the condition is technically not 10CFR Part 21 reportable. However, due t'o the significance of'he potential pump degradation, Rochest'er Gas and Electric is submit'ting voluntary notification.

Rubbing between the pumping ring and the pump housing could cause degradation to the pumping ring with the potential for damage to the pump rotating assembly.

Condition is technically not Part 22 violation due to date of occurrence (prior to 2978).

Date obtained: April 28, 2989 Basic Components Affected:
