Our conclusion is that the radiation doses received were consistent with our

expectations and previous experience with other work in the same areas.

A review of our ALARA training program revealed that the subject of radiation

exposure control is thoroughly covered. The effectiveness of this training

.

was confirmed during our interviews.

All personnel questioned were very con-

'

scious of radiation exposure and its potential effects.

The combination of

intervicwee statements and our own review lead us to conclude that our ALARA

training is effective.

Although the Supply System believes this allegation was made for personal

reasons, several actions appear reasonable to further enhance our ALARA

program. Plant Management already has held a meeting with support contractor

management.

Increasing supervisor surveillance of work activity from an ALARA

,

standpoint and overall performance effectiveness were the topics discussed.

A plant management staff meeting will be held to heighten ALARA awareness

through discussion of this allegation in relation to ALARA effectiveness.

Additional ALARA coordinators have been assigred to cover work tasks performed

during this annual plant outage.
