Detroit iSOn (2000 Second Avenue Detroit. Mcrugan 48226 313) 237-8000 April 14, 1983 EF2 - 62,467 Director of Nuclear Reactor Regulation Attention:
Mr. B.J. Youngblood, Chie f Licensing Branch No. 1 U.S. Nuclear Regulatory Commission Washington, D.C. 20555
Dear Mr. Youngblood:
Re fe renc e : Enrico Fermi Atomic Power Plant, Unit 2 NRC Docket No. 50-341
Subject:
Emergency Operations Facility (EOF) -
Alternative to Supplement 1 of NUREG-0737 Table 1, (Generic Letter 82-33)
December 17, 1982 As suggested in NRC Generic Letter 82-33 and the Fermi 2 Safety Evaluation Report, Supplement 3 (NUREG-0798), Detroit Edison proposes an alternative for implementing the guidelines for an EOF as described in Supplement 1 of NUREG-0737, Table 1.
Detroit Edison has a completed EOF as described in the FSAR, Appendix H. III. A. I.2, and letter EF2-62,262 ( April 15, 1983). The facility is located in the lower level of the Nuclear Operations Center on owner-controlled property approximately 6,000 feet (1.1 miles) southwest of the Fermi 2 reactor.
The EOF is equipped with ventilation isolation and HEPA filters.
The concrete shield walls provide a protection factor of 20 based on the attenuation of 0.7 MeV gamma radiation.
The following factors were also considered:
Annual average X/Q and D/Q values in the SW/WSW sectors are o
among the lowest for the site.
o Radioactive effluents are released from the containment through the Standby Gas Treatment System and iodines are removed by the charcoal filters at an ef ficiency of 99%.

Mr. B.J. Youngblood EF2 - 62,467 Page 2 An alternate EOF has been selected at Detroit Edison's Wayne / Monroe Division Headquarters, 26 miles northwest of the Fermi 2 site.
The facility has adequate communications equipment and sufficient space to accommodate the additional personnel required for continuity of dose projection and decision-making capability. Portable equipment will be provided for the personnel to perform their assigned functions.
Additionally, the Wayne / Monroe Division Headquarters is readily accessible from several directions, including Fermi 2 via Interstate freeways and Michigan highways.
Detroit Edison believes the alternate EOF, located 26 miles from Fe rmi 2, me e t s the intent of Option 1 of Table 1 in Supplement I to NUREG-0737 and requests that an exception be made to the 10 to 20 mile guideline.
Should you have any questions cons ining the above, please contact Mr.
Larry E. Schuerman on (313) 586-4207.
Sincerely,
