( ) .

1.1 Objective Provide guidance to the following Station Emergency Response Organization personnel for coordination of actions to maintain radiological controls; to analyze samples for airborne radioactive contaminants and loose surface contamination; and to obtain radiation l dose rates for specific points and areas within the Millstone Station protected area:

RMT #1 l

= RMT #2 1.2 Discussion During initial SERO activation, on-shift Health Physics Technicians comprise RMT #1 to provide control room health physics support and to i conduct in-plant surveys and sample analysis. Upon EOF activation, the MRCA assumes control of RMT #1, and assigns additional on-site RMTs for survey and sample analysis.

RMT #2 members provide evacuee monito- ,5; at the NAP and SAP.

Other HP Technicians may be assigned to ye , im surveys, collect samples, aid in radiological control at othei ;e adons, or provide decontamination support.
