SUBJECT:
NRC INSPECTION REPORT NOS. 50-317/99-04 AND 50-318/99-04
Dear Mr. Cruse:
This refers to the special onsite safety inspection by a team of NRC inspectors assembled from
J
staff located at Region I, Office of Nuclear Reactor Regulation, Office of Nuclear Regulatory
/
Research, and Region ll, conducted during the period April 5 - 16,1999, at the Calvert Cliffs
Nuclear Power Station. This inspection was the second of three planned visits to verify Calvert
Cliffs Nuclear Power Station's license renewal program is in compliance with the requirements
of the rule for license renewal, and is consistent with Baltimore Gas and Electric's license
renewal application and the NRC staff's safety evaluation. The enclosed report documents the
results of this insperdhn.
The inspection revegicd a few potential and plausible aging effects the NRC team determined
should be included in the license renewal application such as water hammer, thermal expansion
,
and structural cracking. The omissions do not constitute, however, a generic problem with
Baltimore Gas and Electric's methodology. All the omitted aging effects identified by the NRC
were placed in the corrective action program for license renewal activities to be addressed by
~ he Life Cycle Management staff at Calvert Cliffs Nuclear Power Plant.
t
The NRC team concluded that in many cases existing procedures or programs, given credit for
aging management in the license renewal application, are not currently able to completely
manage the aging effect. However, the process of integrating aging management into the
existing site processes and programs is being developed and the NRC team saw evidence of
the early stages of a system that will take care of these problems.
In general the NRC inspection team concluded that Baltimore Gas and Electric properly
implemented the aging management methodology approved by the NRC and the references
and documentation supporting the information in the license renewal application are in auditable
and retrievable forms. The NRC inspection team also concluded there is reasonable assurance
the effects of aging will be adequately managed in order to maintain the intended function (s) of
the systems, structures, and components at Calvert Cliffs Nuclear Power Plant during the period
of extended operation consistent with the current licensing basis.
