'T Wis change results fra the implementation of 10 CFR 50.49 on Plant Hatch Unit 2..
See safety-related motors were changed in order to meet accident environment requirements.
We requested; change to 'Iw:hnical Specifications e
.results fra the need :to show the new primary contaiment electrical penetration c over-current-breaker setpoints-to acconnodate - these newly
-installed motors.
%ese proposed setpoint values were derived using the-
- criteria for the other setpoints in the Table.
In each case, the over-current
. breaker value is a few percent (1-5%). of the rated mperage of the electrical-penetration.
ne breaker would protect the penetration in the event of a -
short in the circuit or in the motor.
Because this change results fra the installation of new motors which were required as a result of 10 CFR 50.49, and because the requested change results
- in no changes to facility operation, this change is consistent wth Item vii of
- the "Exanples of Amenchents that are Considered Not Likely to Involve
~
Significant Hazards ' Considerations" listed on page 14,870 ' of the April 6,.
