Discussion Ite=s
.
ge;;...
Specific ite=s discussed are su==arized below:
KyME a..
_5:t-A.
Trial Inspection Program affect en the facility co= pared to pre-vious inspection efforts.
555"
- .T.."*~~.'..
1.
Met-Ed indicated that inspection frequency at first appeared f""
to be abnormally high.
Inspection frequency now has decreased
-'
to more nor=al levels.
2.
Met-Ed indicated that key personnel were involved in the Trial
"
Inspection Program efforts on about the sa=e level as the previous inspection program.
Clerical personnel appeared to be expending more ti=e in supporting the Trial Program than in the previous inspection program.
A comparison of licensee manhours to support the Trial Inspection Program and the Routine Inspection Program was cuggested as a meaningful method of evaluating the Trial Inspection Program affect on
=
the facility.
G 3.
Met-Ed indicated the diverse inspectors now conducting inspec-tions under the Trial Inspection Program were causing additional e__
time to be expended in retracing areas that had previously been resolved under the Routine Program.
B.
Trial Inspection Program effectiveness campared to previous inspec-
-
tion efforts.
1.
Met-Ed indicated that it was premature at this point to state the effectiveness of the Trial Program co= pared to the Routine Program.
.
2.
An opinion was expressed that the Trial Program apparently removed some inspector lattitude with respect to judgement as compared to tie Routine Program.
The licensee was advised that his ce==ents/ concerns would be evaluated.
