LIMERICK GENERATING STATION EMERGENCY PLAN IMPLEMENTING PROCEDURE

[ i EP-315 CALCULATION OF OFFSITE DOSES DURING A RADIOLOGICAL EMERGENCY USING RMMS IN THE MANUAL MODE 1.0 PURPOSE The purpose of this procedure is to provide guidelines to-RMMS operators and dose assessment personnel who are using l

RMMS to calculate offsite doses during a potential or actual radiological emergency.

I . The manual mode of RMMS will allow the operator to bypass the use of real time radiation and. meteorological data, enabling him to enter data of his~own choosing.

Operation of RMMS in the manual mode is useful for investigating offsite doses during Emergency Plan exercises I and in the event that radiation or meteorological data are u'navailable in the rerl time mode.
