SUBJECT:
NUREG 0737, Item III.A.2 Imp rov ing Licensee Emergency Preparedness Daar "r Eisenhut:
MUREG 0737, " Clarification of T"I acticn Pl an ?equirem ents,'
item III.A.2 requires the implementation of radiological emergency response plans by April 1,
In91.
These plans address the primary and backup meteorological measurements, and the dose calculational methodology relating to the transport and diffusion of gasacus ef fluents.
The '!U R EG 0737 requirament references the Cuidances presented in NUREG 0654, Appendix 2
" Meteorological Criteria for Emergency Preparedness of Operating Nuclear Po we r Plants."
Cur plans and schedule for im plem en ting the NRC requirements identified in NUREG 0737 are as follows.
1.
NRC RECUIRE'4E'IT:
Provide a description of the radiological emergency response plans that includes elements o f NUREG 0654, Appendix 2.
Response
Philadelphia Electric Company's plans for addressing Appendix 2 are described in the responses provided to the 'IRC requirements i
2, 3, and 4 below.

NRC REQUIREMENT:
Submit implementing procedures desc ribing methods, systems, and aquiomant to assess and monitor actual or potential offsite consequences of a radiologica1' emergency condition.
Resoonse The method, systems,and equipment to assess and moaitor actual or potential offsite consequences of a radiological emergency are described.in procedure EP 316, and transmitted to the MRC with my latter d, tad Fabruarv 20, 1021 To 216 ss wall as tha othar implementing proced ures fo r the Emergancy Plan currently in review by the NRC will be continuously reviewed and revised as necessary during the transition period from the old plan to the complete implementation of the new plan.
Revised procedures will be submitted to the NRC for-review.
Meteorological inputs for this procedure consist of the following:
1.
'41nd speed and direction from a 320 f t. Aerovane on the
-Peach Bottom primary tower. (representative of a stack releasc}
i 2.-
Wind speed and d!rection from a 75 f t.
Aerovane on the Peach Bottom primary towe." (represantative of a vent release) 3 Wind speed and direction from a 92 ft. Aerovane on the Peach Bottom backup meteorological tower.
4.
-Turbulence. class-(Gustiness) determined - fron the fluctuations of the wind direction trace.
3
'NRC REQUIREMENT:
Implement - the radiological emergency response plan by April 1,
1991 with the exception of the
. Class B model described in NUREG 0654,' Appendix 2.
Response
The ' alternative for meteorological measurements described in
-NUREG 0737, item III. A.2 is presently in effect. ~The existing meteorological monitoring. system : consists of:
1.
A primary tower with Aerovanes at the 75.ft. and 320 ft.
level and thermohms at 76 f t.
146., _and E316 f t. -levels; 2.
A backup. tower with aerovanes at 30 ft. and 92 ft.. and thermohms at 33 f t. and 39 ft.
i Instrument output is. displayed on charts in the control room.
- Dose. calculations -are performed in accordance ' with procedure EP -
316 that has been written in response. to the requirement.to meet 4
1 Page 3 the ch-
'teristics of the Class A model in Appendix 2 of NUREG 0554 cedures have been established f or phone access by the o-NRC ir. one event of a radiological emergency.
4 MRC REQUIREMENT: By July 1, 1931, a functional description of the-upgraded programs (of fsite dose com pu ter) and schedule for installation and full operational capacity shall be r ovided.
-Resconse We 'are evaluating various suppliers of digital meteorological equi pment, and developing a computer dose model consistent with the chtracteristics of the Class A model outlined in the assessment capability of Appendix.2 to NUREG 0654 We expect to provide a description and schedule of the upgraded capabilities by July 1,
1981 as requested.
We believe this. description of our current and long term capabilities for real time dose predictions will meet the MRC~
criteria presented in MUREG 0737, item III.A.2.
