Dear Mr. Carns:
SUBJECT: NRC COMBINED INSPECTION 50 245/97 203:50 336/97 203;423/97 203
On October 1,1997, the NRC completed an inspection at your Millstone Station, Units 1,2
& 3 reactor facilities. The enclosed report presents the results of that inspection.
The staff observed improved performance in multiple areas during this inspection period.
As outlined in the Executive Summary and the supporting Report Details, the staff noted
good performance in selected areas across all three units, for example: Improvements in
the tagging controls and shift turnovers at Unit 2; the quality of Significant items List
packages and technical specification compliance at Unit 3; and operating experience staff
performance for Unit 1.
However, four violations and one apparent violation of NRC requirements also were
identified during this inspection period. One violation involved the failure to properly ensure
that safety-related work at Unit 1 is correctly coded and reviewed by the Quality Control
(OC) group. The report also describes a Unit 2 violation wherein an operating procedure
f ailed to address thermal binding concerns for the Unit 2 steam admission valves for the
turbine driven auxiliary feedwater pump. Another violation involved shipping activities in
which a package of radioactive material was transported from your f acility to the
Connecticut Yankee Atomic Power Station, which, upon receipt, was determined to have
external radiation levels in excess of regulatory limits. Finally, a recurring violation was
identified in the area of radiological worker practices. Four examples of wo kers improperly
entering or exiting the radiologically controlled area at each of the units were identified
.: }
V
during the poi.od September 816,1997. Although corrective actions taken to address
previously identified violations in this area have generally reduced the rate at which such
' f, ,-
strors are occurring, they have not been fully effective.
-
These violations are cited in the enclosed Notice of Violation, and the circumstances
g
surrounding the violations are described in detail in the enclosed report. Please note that
\\
i
you are required to respond to this letter and should follow the instructions specified in the
enclosed Notice when preparing your response. The NRC will use your response,in part,
to de; ermine whether further enforcement action is necessary u ensure compliance with
regulatory requirements.

The apparent violation idertified by you at Unit 3 represents a significant safety concem._
[
Licensee Event Report 423/96-029 discusses a condition that alone could have caused the
loss of the emergency cort cooling capabilities of the charging and high head safety
injection systems. This apparent violation at Unit 3 is being considered for escalated
enforcement action in accordance with the " General Statement of Policy and Procedure for
NRC Enforcement Actions" (Enforcement Policy), NUREG 1600. You will be advised by
'
separate correspondence of the results of our deliberations on this matter. No response
regarding this apparent violation is reouired at this time; however, any corrective actions
deemod appropriate should be instituted in a timely manner Please be advised that the
number and characterization of apparent violations described in the enclosed inspection
report may change as a result of further NRC review.
'
The Unit 1 staff's response to a Nuclear Oversight identified issue concerning the
installation of temporary lead shielding in the plant was prompt and comprehensive.
Additional shielding concerns were identified by the line organization, as well as indications -
'
of a larger programmatic problem originating from a lack of ownership for the program.
i
The health physics department is appropriately assuming ownership of the Unit 1 shielding
control program.
At Unit 2, you have been sur essfulin addressing the longstanding problems associated
l
with tagout adequacy as demonstrated by good performance over an extended period,
i
Strong celf assessments and corrective actions associated with tagging have been the
driving force behind continued improvements in this area.
On September 24,1997, you reported that the Unit 2 engineered safety feature actuation
system (ESAS) cabinets were inoperable because new power supplies that were installed
"
in a 1994 modificttion could have blown the power supply fuses if an ESAS actuation
were to occur, thereby preventing tho actuation of safety equipment. This event is of
particular concern to the NRC and warrants continued licensee management focus. At the
end of the inspectior, period, NRC and licensee evaluations of this concern were ongoing
and will be covered in a future NRC inspection report,
i
t
Substantial work remains to be done to achieve closure of the Generic Letter (GL) 8910
motor operated valve (MOV) program at Units 2&3. The Units 2&3 GL 8910 program had
recently been significantly revised. MOV design basis reviews, modifications, overhauls,
and additional testing remained to be completed. Appropriate resources were evident in
forming a new MOV organization to support all of the Millstone units and to correct MOV
program deficiencies. You agreed to provide a supplemental response regarding Generic
Letter 95 07 to address pressure locking and thermal binding concerns for certain MOVs at
Unit 2. You also agreed to discuss in this response your corrective actions to the violation
associated with thermal binding that is discussed above. If these commitments are not
correct, please notify this office as soon a practical.
This inspection report discusses a number of issues contained in the Unit 2 Significant
items List (SIL). Although corrective actions were completed satisfactorily for specific
technicalitems (SIL Nos. 22,29, and 35), no SIL items involving the broader
programmatic issues were able to be closed,

Your progress on providing significant items list (SIL) packages for Unit 3 is proceeding
smoothly and prrigress is being made on SIL issue inspection, as is evidenced in the.
enclosed inspection report. However, there have been some examples of problems with
the comprehensiveness of the completed corrective actions for certain SIL items. Also, as
indicated in the enclosed report, and in the prcvieus inspection report, improvements in
your programmatic ceaMI of several major technical / topical areas (e.g., environmental
qualh'ication, MOVs, electrical separation) have been noted and the SIL items associated
with these issues appear properly directed toward resolution. Ho" ver, in other Sll areas
(corrective action, vendor programs, MEPL), which appear to represent engineering
programs of a more general topical natcre and which are applicrble to all three urits,
prompt and sustained progress toward the disposition of NRC c ,ncerns is less evident.
Given the importance of the relation of SIL item closure to the readiness of Unit 3 for
restart, additional management attention to the resolution of these general topical Sllitems
appears warranted,
in accordance w.<h 10 CFR 2.790 of the NRC's " Rules of Practice," a copy of this letter
and its enclosures will be placed in the NRC Public Document Room (PDR).
