1.0 INTRODUCTION

l 1

By letter dated September 10,1998, Carolina Power & Light Company (CP&L) proposed to revise the Brunswick Steam Electric Plant Unit Nos.1 and 2 (BSEP) Radiological Emergency Response Plan (RERP) by relocating the Technical Support Center (TSC) outside the protected area. This revision will be an exception to the TSC location guidance in Supplement 1 to NUREG-0737,"Clarif; cation of TMl Action Plan Requirements, Requirements for Emergency Response Capability". Specifically, the proposed revision would eliminate the current RERP requirement to incorporate the TSC, upon activation, into the protected area.

2.0 EVALUATION l

BSEP's RERP currently stipulates that the TSC is to be incorporated within the site's protected area upon activation. Prior to activation of the TSC, the security force members must realign the protected area boundary to encompass that portion of the TSC/ Emergency Operations Facility (EOF) Building that currently houses the TSC facilities. The realignment normally involves performance of a lengthy search of all areas of the TSC and compensatory measures to enhance intrusion detection. Currently, upon declaration of an emergency, the time needed to activate the TSC is approximately 60 to 70 minutes. With the proposed revision, the time required to activate the TSC is reduced to approximately 30 to 40 minutes. With the TSC not in the protected area, the need to search and secure the TSC is not required, resulting in up to a 30 minute reduction in activation time.

CP&L has provided methods to ensure the availability of specific data and information from the control room, thus limiting the need to send TSC personnel to the control room. Plant data is available from the Em<cgency Response Facility Information System (ERFIS) and the Safety Parameter Display System. In the event of an ERFIS failure, there is an Emergency Response Organization communicator whose function is to transmit ERFIS data points from the control room to the TSC. Information may be transferred between the TSC and the Control Room by existing communication systems that include the site telephone system, VHF radio system and 9904070054 990330 #

public address system. An Automatic Ring Down telephone provides a direct communication link between the Shift Superintendent in the Control Room and the Plant Operations Director in j

the TSC.

If it should become necessary to travel between the TSC and the Control Room, the current

- route through Gate 8 remains available to provide access through the protected area boundary.

Security support is readily available and required to open Gate 8. The time to dispatch security and open the gate is mimmal, less than one minute. Additionally, the main protected area l access point is available as an alternate route through the Central Access Portal building, which is located adjacent to the TSC/ EOF building. The dispatch of security to open Gate 8 slightly increases the transit time from the TSC to the Control Room to less than 3 minutes. This  ;

exceeds the guidance in NUREG-0696, Section 2,2, that states "The walking time from the TSC  !

to the control room shall not exceed 2 minutes." However, the difference in the transit time, less than one minute, is offset by the reduction in the time to activate the TSC and the enhanced i communications capabilities available between the TSC and the Control Room.

1 3.0 Conclusion '

The NRC staff has evaluated CP&L's proposed revision to the BSEP RERP. Based on a review of the licensee's submittals and on the basis that the revision does not decrease the effectiveness of the RERP, the staff recommends that the licensee's proposed revision to eliminate the commitment to require incorporation of the TSC into the protected area be approved.
