SUMMARY
OF THE APRIL 7,1998, MEETING WITH REPRESENTATIVES OF BALTIMORE GAS AND ELECTRIC (BGE) COMPANY CONCERNING THE !
CONTROL ROOM HABITABILITY ISSUE WITH A MAIN STEAM LINE BREAK INTRODUCTION In conjunction with a license amendment request of January 31,1997, to change the reactor i coolant system flow requirements to allow increased steam generator tube plugging, the NRC l staff identified concems regarding the dose to the control room during various accidents. In addition to request for additional information of March 30,1998, the staff felt it necessary to have a meeting with the licensee to gain further knowledge on the licensee's plans to alleviate the dose to the control room and the status of Calvert Cliffs to meet General Design Criterion (GDC) 19 for all postulated accidents. Enclosure 1 provides the list of attendees of the meeting.
Enclosure 2 provides the licensee's presentation on the in leakage concems of the control room ventilation system. Enclosure 3 provides the staff's concept of the control room ventilation system.
1 DISCUSSION The staff identified the concem that the March 17,1998, submittal on control room operator dose /
was based upon the condition of the control room ventilation system repairs and modifications are completed. The existing control room condition was shown to have an in leakage, based
/
upon tracer gas tests, of greater than 4000 cfm. No analysis has been presented to the staff that d provides the doses based upon the existing control room conditions. It was prudent for the U.
licensee to identify the in leakage into the control room ventilation system and to make modifications that would seal the areas of concem especially in the roof area where the consequences of a postulated steam line break would be most severe. Also, the licensee needed to tell the staff how they are presently meeting GDC-19.
Enclosure 2 provides the licensee's presentation on the testing of the control room ventilation system for in leakage and the areas of modifications being made or planned to reduce the leakage. The licensee indicated that the modifications would not be completed before December 1999. The licensee also presented a discussion of their response to the request for additional information of March 30,1998. This response is soon to be sent to the NRC. In addition the licensee will include in that response a concem of the sequence of shutdown - whether reactor trip, turbine trip and loss of offsite power are assumed to occur concurrently for a main steam line break accident.
Discussion was held on the surveillance requirements for the laboratory testing of the charcoal filters in the control room ventilation system. Calvert Cliffs current Technical Specifications requires the filters to have a 90% efficiency. The Calvert Cliffs's procedures test the filters for 94% efficiency which, in their view, would provide a margin to allow degradation between refueling outages of 4%. Such a procedure could be changed through the 10 CFR 50.59 process. The staff's view was that the surveillance should incorporate a safety factor. This would assure at least a 90% efficiency through out the operating cycle and would provide some
~

2-assurance that a procedure change would not be made which inadvertently negates the previously approved licensing analysis. The staff recognized that because of the unique operation of the control room ventilation system during an accident (the ventilation system is operated in the recirculation mode), with technicaljustification, the filters could be tested at a relative humidity of 70% rather then the existing 95%.
CONCLUSIONS The staff concluded that the licensee needed to document to the staff an analysis which demonstrates the Calvert Cliff Plant's capability to meet GDC 19 in its present condition. The ,
staff also needs the licensee to document the basis for delaying control room repairs until December 1999. The staff has requested a response to the testing requirements for the l efficiency of the charcoal filters and how the requirements would be controlled. Finally, clarification is required as to whether, for a main steam line break accident, the reactor trip, turbine trip and loss of off site power are assumed to occur concurrently.
The licensee indicated they would be responding by letter shortly to the accident analysis issues raised in the March 30,1998, request for additional information and also to the sequence of shutdown during a main steam line break accident. For the charcoal filter and other issues, the licensee will consider the staff's views and provide a response later.

April 20,1998 assurance that a procedure change would not be made which inadvertently negates the previously approved licensing analysis. The staff recognized that because of the unique operation of the control room ventilation system during an accident (the ventilation system is operated in the recirculation mode), with technicaljustification, the filters could be tested at a relative humidity of 70% rather then the existing 95%.
CONCLUSIONS The staff concluded that the licensee needed to document to the staff an analysis which demonstrates the Calvert Cliff Plant's capability to meet GDC 19 in its present condition. The l staff also needs the licensee to document the basis for delaying control room repairs until December 1999. The staff has requested a response to the testing requirements for the -
efficiency of the charcoal filters and how the requirements wou'd be controlled. Finally, clarification is required as to whether, for a main steam line break ~ accident, the reactor trip, j turbine trip and loss of off site power are assumed to occur concurrently.
- The licensee indicated they would be responding by letter shortly to the accident analysis issues raised in the March 30,1998, request for additional information and also to the sequence of shutdown during a main steam line break accident." For the charcoal filter and other issues, the licensee will consider the staff's views and provide a response later.
