SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACT 0k FECULAT100 RELATED TO AMENDHENT NO. 47 TO FACILITY OPERATING LICENSE NO. _NPF_-43 DETR0li EDISON COMPANY WOLVERINE POWER SUPPLY COOPERATIVE,,,lNC,0RPORATED FERMI-2 i
r DOCKET NO. 50-341 1.0 lk,T,R,00,UCT10N Py letter dated November 15, 1906, theDetroitEdisonCottpany(DEcoorthe licensee) requested an.er.dment to the Technical Specifications (TSs) appended tc T6cility Cperating License No. NPF-43 for fermi-2. The proposed r.:.trdn.ent would chtr.ge the Technical Specifications to c16rify the location of the ncble gas inonitor in the Fermi-2 offgas system.
In eddition, the term " HOT STANELY" in tht action st6tement of Section 3.11.2.7 of the TSs would be r
replaced by "STAkTUF, with 611 nain stear., lines isolated."
2.0 EVALUATION Section 3/4.11.2.7 of the Fermi-2 TSs provides a liritir.g condition for operation (LCO) and suritillence requiren.ents (SL) for the gross radioactivity rate of noble gases from the m61n concenstr.
The original plant TSs did not correctly it.dicate the loc 6 tion of the not,le gas incleitor fct the mbin ccnder.scr. The proposed amendnent will provide a rore ecturbte dt.scriptici. cf the monitot in question.
The cher ge of ternirology from "at the main condenser steam jet air ejector" to "et the discharge of the 2.2 rninute de16y piping" does not thenge the raonitor beirg used for this function. The n.cnitor at the discharge 2.2 tr.inute

delay p(iping is the nionitor reviewed by the staff in the Fermi-2 Safety Evaluation Report NUREG-0798) to measure noble gas activity from the main condenser released via the offges system and is included in TS 3/4.3.7.12, Radioactive Gaseous Effluent Monitoring Instrumentation.
This proposed change is administra-tive in nature and has no 6ffect on safe plant operation.
The pt oposed amendirent also would change the term
- HOT STANDBY" to "STARTUP, with ell train steam lines isolated" in the TS action statement. The term " HOT STANDEY" is not defined in the Fermi-2 TSs. The proposed wording retains the intent of reducing the power leve1 of the reactor in order to reduce noble gas production in the reactor core followirg a fuel ftilure and stc,pping the Ocble gas release by iso 16 ting the main stect11nts.

The proposed changes provide clarification to the TSs.
The changes provide clearer guidance for monitoring the gross radioactivity rate of noble gases from the main condenser and they require actions to be taken if the radioactivity rate is greater than the LC0 in the TSs.
The changes are administrative in a
nature and do not change the intent of the TSs or affect the safe operation of
.the plant.
Based on the above evaluation, the staff finds the proposed changes neeptable.
M 3.0 ENVIRONMEJjTALCONSIDERATION This amn, ::Mont involves changes in requirements with respect to the installamo or use of a facility component located within the restricted area e
E as defined in 10 CFR Part 20.
The staff has determined that the amendment involves no significant increase in the amounts, and no significant change in C
the types, of any effluents that may be released offsite and that there is no significant increase in individual or cumulative occupational radiation exposure.
g The Commission has previously issued a proposed finding that this amendment involves no significare hazards consideration and there has been no public comment on such finding.
Accordingly, this amendment meets the eligibility e
criteria for categorical exclusion set forth in 10 CFR 51,22(c)(9).
Pursuant to 10 CFR 51.22(b), no environmental impacts statement or environmental assessment need be prepared in connection with the issuance of this amendment.
4.0 CONCLUSION
We have concluded, based on the considerations discussed above, that (1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the proposed manner, and (2) such activities will be conducted in compliance with the Commission's regulations, and the issuance of this amendment will not be inimical to the common defense and security or to the health and safety of the public.
