4 NOTICE OF VIOLATION Baltimore Gas and Electric Company Docket Nos. 50-317;50-318
-Calvert Cliffs Nuclear Power Plant License Nos. DPR-53; DPR-69 EA 98-225 During an NRC inspection conducted from March 30 to April 3,1998, three violations of NRC requirements were identified. In accordance with the " General Statement of Policy i
and Procedures for NRC Enforcement Actions," NUREG 1600, Revision 1, the violations are listed below:
'A.
10 CFR 50.65(a)(1) requires, in part, the holders of an operating license shall monitor the performance or condition of SSCs within the scope of the monitoring program as defined in 10 CFR 50.65(b) against licensee-established goals, in a manner sufficient to provide reasonable assurance that such SSCs are capable of fulfilling their intended functions. Such goals shall be established commensurate with safety. When the performance or condition of an SSC does not meet established goals, appropriate corrective action shall be taken.
10 CFR 50.65(a)(2) requires, in part, that monitoring as specified in 10 CFR 50.65 ta)(1)is not required where it has been demonstrated that the performance or condition of an SSC is being effectively controlled by performing appropriate preventive maintenance, such that the SSC remains capable of performing its intended function.
j J
Contrary to the above, the licensee permitted a number of SSCs within the scope of the Maintenance Rule to remain under 10 CFR 50.65(a)(2) when preventive maintenance failed to assure that these SSCs remained capable of performing their intended function, as evidenced by the following examples, each of which constitutes a separate violation:
1.
On July 10,1996, the licensee elected to place containment spray system L
_ under Section 50.65(a)(2). Following a repetitive functional failure, identified by the NRC, which occurred in March 1997, the licensee incorrectly allowed i
'this system to remain under 10 CFR 50.65(a)(2). The repetitive functional failure demonstrated that the preventive maintenance being performed on this system was not appropriate in that it failed to assure that the system i
remained capable of performing its intended function. The system should have been placed under 10 CFR 50.65(a)(1) following the repetitive failure.
L l
l 2.
On July 10,1996, the licensee elected to place the 4KV electrical distribution bus, instrument air system air amplifier, hydrogen recombiner, hydrogen analyzer and auxiliary feed water systems under Section L
50.65(a)(2). Following repetitive functional failures and/or excess j-
- unavailability times,'the licemee incorrectly allowed the systems to remain -
under 10 CFR 50.65(a)(2) for excessive periods of time ranging from three months to 1.5 years. The repetitivs functional failures and/or excess unavailability times demonstrated that the preventive maintenance being performed on these systems was not appropriate in that it failed to assure that the systems remained capable of performing there intended functions.

i L
la-l L

. The systems should have been placed under 10 CFR 50.65(a)(1)in a timely manner commensurate with safety following the repetitive functional failures and/or excess unavailability times.
1 B.
10 CFR 50.65(a)(1) requires, in part, that holders of an operating license shall i
monitor the performance or condition of structures, systems and components
-(SSCs),within the scope of the monitoring program, as defined by 10 CFR 50.65(b),
jl against licensee established goals, in a manner sufficient to provide reasonable L
assurance that such SSCs are capable of fulfilling their intended functions. Such L goals'shall be established commensurate with safety and, where practical, take into
('
account industry-wide operating experience. When the performance or condition of-(-
a SSC does not meet established goals, appropriate corrective action shall be taken.
L i
?
10 CFR 50.65(a)(2), requires, in' part, that the monitoring as specified in 10 CFR 50.65(a)(1)is not required where it has been demonstrated that the performance or
- condition of a SSC is being effectively controlled by performing appropriate
. preventive rnaintenance, such that the SSC remains capable of performing its intended function.
L
' Contrary to 10 CFR 50.65(a)(2), as of. July 10,1996, the time that the licensee elected to not monitor the performance or condition of the emergency diesel -
^ generator building heating, ventilation and air conditioning system against j
' established goals pursuant to the requirements of Section (a)(1), the licensee failed
, to demonstrate that the performance or condition of SSCs within the scope of 10 i
.CFR 50.65 had been effectively controlled by performing appropriate preventive L
~ maintenance. Specifically, the licensee had failed to establish performance measures for the system and was therefore unable to effectively demonstrate the system remained capable of performing its intended function.
)
l C.
10 CFR 50.65(a)(1) requires, in part, that the holders of an operating license shall
' monitor the performance or condition of SSCs within the scope of the rule as
. defined _by 10 CFR 50.65(b) against licensee-established goals, in a manner l'
sufficient to provide reasonable assurance that such SSCs are capable of fulfilling their intended functions. Such goals shall be established commen'surate with safety.1 When the performance or condition of an SSC does not meet established
. goals, appropriate corrective action shall be taken.
p 10.CFR 50.65(b)(1) requires, in part, that the holders uf an operating license shall
+
include within the scope of the monitoring program specified in 10 CFR 50.65(a)(1),
safety related structures, systems, or components that are relied upori to remain L
- functional during and following design basis events to ensure the integrity of the
-reactor coolant pressure boundary, the capability to shut down the reactor and (maintain it in a safe shutdown condition, and the capability to prevent or mitigate
.the consequences of accidents that could result in potential offsite exposure
,s comparable to the 10 CFR, Part 100 guidelines. The scope shall also include non-e 1
i'.
]
w
l l
r l
3 safety related structures, systems, or components that are relied upon to mitigate accioents or transients, or are used in the plant emergency operating procedures, or whose failure could prevent safety-related structures, systems, and components from fulfilling their safety-related function, or whose failure could cause a reactor l
scram or actuation of a safety-related system.
)
Contrary to the above, as of July 1997, the licensee had failed to include vithin the
. scope of the Maintenance Rule program the portion of the emergency lighting -
. system located outside the control room, which is required for safe shutdown of the plant.
Pursuant to..the provisions of 10 CFR 2.201, Baltimore Gas & Electric Company is hereby required to submit ; a written statement or explanation to the U.S. Nuclear Regulatory Commission, ATTN: Document Control Desk, Washington, D.C. 20555 with a copy to the Regional Administrator, Region I, and a copy to the NRC Resident inspector at the facility L
that is the subject of this Notice, within 30 days of the date of the letter transmitting this
-Notice of Violation (Notice).- This reply should be clearly marked as a " Reply to a Notice of Violation". and should include for each violation: (1) the reason for the violation, or, if g
l
~ taken and the results achieved, (3) the corrective steps that will be taken to avoid further contested, the basis for disputing the _ violation, (2) the corrective steps that have been L
violations, and (4) the date when full compliance will be achieved. Your response may
- reference or include previous docketed correspondence, if the correspondence adeqmtely j
- addresses the required response. :lf an adequate reply is not received within the time.
~
. a specified in this Notice, an order or a Demand for Information may be issued as to why the kcense should not be modified, suspended, or revoked,1or why such other action as may I
be proper ' hould not be taken. Where good cause is shown, consideration will be given to L
s extending the response time.
If.you contest' this enforcement action, you should also provide a copy of your response to
' the Director, Office of Enforcement, United States Nuclear Commission, Washington, DC 20555-0001.
Because your response wil! be placed in the NRC Public Document Room (PDR), to the extent possible, it should not include any personal privacy, proprietary, or safeguards information so that it can be placed in the PDR without redaction. If personal privacy or proprietary information is necessary to provide an acceptable response, then please provide a bracketed copy of your response that identifies the information that should be protected 7
and a redacted copy of your response that deletes such information. If you request withholding of such material, you must specifically identify the portions of your response that you seek to have withheld and provide in detail the bases for your claim of
. withholding (e.g., explain why the disclosure of information will create an unwarranted L
invasion of personal privacy or provide the information required by 10 CFR 2.790(b) to support a request for withholding confidential commercial or financial information). If
. safeguards information is necessary to provide an acceptable' response, please provide the level of protection described in 10 CFR 73.21.

ATTACHMENT 1 CALVERT CLIFFS ENFORCEMENT CONFERENCE l
)
l PRINCIPAL NRC CONCERN BG&E apparently failed to adequately implement the Maintenance Rule by July 1996. Further, prior to the inspection BG&E was in possession of l
self-assessment type information that indicated that the program established would not be acceptable to the NRC.
.l l
l I
VIOLATION 1 Contrary to 10 CFR 50.65(a)(2), BG&E permitted a number of SSCs within the scope of the Maintenance Rule to remain under (a)(2) status for extended periods of time after performance criteria was exceeded (nine examples were noted by the team, potentially many others).
The team identified a repetitive FF on the CS system that should have placed the system in (a)(1) status in March 1997. BG&E's tracking system
. failed to identify the CS system FFs as repetitive failures.
VIOLATION 2 Contrary to,10 CFR 50.65(a)(2), BG&E did not establish performance measures for the emergency diesel generator building HVAC system and
-therefore did not effectively demonstrate the system remained capable of performing its intended function.
VIOLATION 3 Contrary to 10 CFR 50.65(b)(1), BG&E feiled to inc!ade the emergency j
l-lighting located outside the control room b tbc scope of the maintenance j
rule.
i L
I
l PROGRAM ISSUES Lack of timeliness in resolving the use of the reliability index as a e
performance measure (identified in 5/96 & again in 10/97 self-assessments).
e.
The program was ineffective in the timely identification of functional failures that delayed the placing some SSCs in (a)(1) status and implementing required actions.
