PLANT VOGTLE TECHNICAL / MANAGERIAL / REGULATORY CONCERNS I.

FAVA MICROFILTRATION UNIT A.

System was purchased, installed and placed into operation in a

process which bypassed all applicable commitments / requirements.

B.

System is located in a building which has had an inadequate safety analysis with regard to containing a potential spill.

C.

Combination of

'A' and

'B' above results in an installation with inferior (regulatorially excluded) materials (i.e.

PVC) in operation in a building with questionable capacity for containing spills.

Of particular concern is a line rupture which could spray against building walls.

D.

Plant management, the PRB and General Manager in particular, have responded in a non-conservative manner by allowing the continued operation of the system.

Specific issues involve a

PRB vote when the main dissenting member could not

attend, excessive GM participation in PRB actions leading to intimidation of members, unreviewed safety questions being identified and not being adequately addressed prior to votes to operate.

II.

DIESEL AIR QUALITY A.

Due to operation with unknown and potentially high dew points, it is unknown as to whether the diesel xnerator air systems have experienced condensation a..d,

as a result, therefore have corrosion products (particulate) in the lines which may jeopardize reliable operation.

B.

In response to a generic NRC letter dealing with diesel air quality, the plant submitted a

response which included a statement that we operated with a dew point of 50 degrees F or less even though we have measured values in excess of this number.

This took place about one year ago.

~j i

III. CAL-CON SWITCHES A.

The manufacturer issued a 'Part 21' on these switches and.

j the plant failed to take timely action.

j B.

Plant may still not have made an appropriate -response on reportabilities.

An LER is involved.

I IV.

DIESEL GENERATOR LER A.

The number of successful starts for the diesel generators i

included in an LER was not correct.

Plant and corporate management took too long to correct this problem.

i B.

Logs of these starts are not easily understood and there is a lack of knowledge on procedural requirements in this area.

V.

PRB/ MANAGEMENT - GENERAL f

A.

The PRB does not act in a consistently conservative-manner in areas of safety and reportability.

Examples l

given were two issues on missed surveillances where the PRB found them to not be reportable and the NRC ultimately issued violations.

Resolution of dissenting votes by PRB members is not pursued as far as it should j

be in certain instances.

B.

When individuals and/or the PRB errs in judgement, the 1

corrective action taken to preclude further occurrences j

is not clear or decisive.
