SUBJECT:
Dear Mr. Stolz:
This letter provides a response to questions received by telephone on December 2, 1982, from the NRC Project Manager regarding the design of the Peach Bottom Emergency Operations l
Facility (EOF).
The following correspondence, previously submitted, provides additional information regarding the design of the facility:
1)
S. L. Daltroff, PECo to H. R. Denton, NRC dated Janauary 2, 1980, and 2)
S.
L.
Daltroff, PECo to D., G. Eisenhut, NRC, dated June 1, 1981.
1.
NRC Question:
Identify the location of the EOF with respect to the plant.
Answer:
The EOF is situated on the second floor of the former l
Peach Bottom Unit 1 Administration Building.
The building is located approximately 1,000 feet from the centerline between the Unit 2 and Unit 3 structure.

2.
NRC Question:
Identify the type of structure used for the EOF.
Answer:
Both the Emergency Operations Facility and the Technical Support Center (TSC) are located within a structural steel supported building that was previously used to house the main control room and administrative office space for the now decommissioned Unit 1 facility.
The building interior was modified to provide the necessary features required of the EOF and TSC, and demonstrated I
to be fully operational during the June 1982 emergency drill.
The building was originally completed in 1963.
3.
NRC Question:
Does the habitability design of the EOF include HEPA filters and provide a protection factor greater than five?
Answer:
HEPA filters are included in the habitability design and provide a protection factor greater than five.
4.
NRC Ouestion:
Do you have either an interim or backup EOF?
Answer The facility described above represents the permanent EOF for Peach Bottom.
No backup EOF is planned.
Generic letter 81-10 recommends that Emergency Operations Facilities located within 10 miles of the i
plant meet the following critera:
a.
Habitability consisting of ventilation isolation with HEPA (no charcoal).
b.
Provide a backup EOF between 10-20 miles.
i.
Mr. John F. Stolz, Chief Page 3
The habitability control system for the EOF has been designed to provide the same radiological habitability as the main control room under accident conditions.
This includes a ventilation system utilizing both HEPA and charcoal filters.
The existing shielding was sufficient for meeting the personnel dose criteria identified in NUREG-0578.
Based on the habitability design for the Peach Bottom EOF that exceeds the criteria of Generic letter 81-10, we requested an exception to the backup EOF criteria in the June 1, 1981 letter (S. L. Daltrof f to D. G. Eisenhut).
Please contact us should you need additional information regarding this matter.
Sincerely,
