NRC Region I Combined Special Inspection Report Nos. 50-31'7/89-11

and 50-318/89-11

!

The enclosed report transmits the findings of the April 17-27, 1989, . special

inspection' concerning two ' operational events and the installation of an unre-

viewed temporary modification at the. Calvert Cliffs facility. These findings <

were discussed with Mr. L. Russell and members of your staff.

On. April 17,.1989, core alterations were performed for approximately 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> and I

35. minutes without the appropriate level of containment integrity being - estab-

~11shed. Again on April 19, 1989, core alterations were performed for approxi-

mately 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> while the containment bounda y was breached. Technical Specifi-

cations (TS) impose special containment integrity requirements during core

alterations. These . two operational events therefore represent an apparent j

violation.- '

On April 22, 1988, a temporary modification was installed on_the Unit 1 Refuel-

ing Machine which your staff subsequently, on April 20, 1989 determined consti- l

tuted.an unreviewed safety question. This temporary modification was installed l

without the TS required Plant Onsite Safety Committee review or an evaluation  !

performed as required by 10 CFR 50.59. This constitutes two apparent

violations.

Of more significant concern to us are the broader implications of these

-events. The NRC is concerned that a lack of control of operations and main-

. ,

'g.

tenance activities at Calvert Cliffs allowed these events to occur.

Accordingly, we have scheduled an Enforcement Conference on May 30,1989, to  !

discuss these events.with you in the NRC Region I Office in King of Prussia,  !

Pennsylvania. We will forward an appropriate notification of enforcement

i

action after the Enforcement Conference.  !
