Maine. At the conclusion of the inspection,' his findings were discussed with Mr. Blackmore

'

and members of the MYAPS engineering and licensing staff.

i

The scope of this inspection included review of your engineering and technical support

effectiveness in resolving a reactor coolant pump vibration pioblem, responsiveness to

.

Generic Letter 92-01 related to reacter vessel material integrity surveillance, and primary

component transient operating cycle monitoring. As the plant increases in age, it is

important to have identified those component and piping areas approaching the numbers of

transient cycles for which they have been designed. Effective performance in these areas by

,

'

your engineering and technical support personnel is important to the stle operation of the

plant and protection of public health and safety.

e

Based on the results of this inspection, your engineering and technical support staff was
