Docket No. 50-336
Northeast Nuclear Energy Company
ATTN: Mr. Edward J. Mroczka
Senior Vice President - Nuclear
Engineering and Operations Group
P. O. Box 270
Hartford, Connecticut 06141-0270
Gentlemen:
Subject:
Routine Resident Inspection 50-336/88-06 (2/8/88 - 3/21/88)
This transmits the report of the above subject inspection of Millstone 2.
No vio-
lations were identified cnd no reply to this letter is required. The inspection
findings have been discussed with Messrs. S. Scace and J. Keenan of your staff.
We wish to call your attention to the control of overtime. Our review identified
12 examples of extensivo overtime worked without prior management approval during
the recently completed outage (Report Detail 9).
Previous concerns in this area
were identified in NRC Inspection 50-336/87-29.
Our review of overtime controls
continues.
We also wish to point out that maintenance "hot" work was performed on the 56'
elevation of the turbine building without a fire watch being stationed (Report
Detail 5.2).
Even though the potential impact was minimal in this case, we view
this as an instance of poor practice.
We have reviewed your February 10, 1988 response to a violation identified in In-
spection Report 50-336/87-25. Your letter addresses corrective actions on the DC
switchgear vital ventilation subsystem chilled water coolers. Your responte and
assessments adequately address our concerns with the DC switchgear chilled water
coolers, and with the management of equipment configuration and performance, We
will continue to monitor for trends in this area during future inspections.
Your cooperation with us is appreciated.

Sincerely,
Originel Sissed M
