Proposed Technical Specification (License Amerdment)

Change - IWiioactive Gaseous Effluent Monitoring Instrumentation (3/4.3.7.12)  !

Pursuant to 10CFR50.90, Detroit B31 son Company hereby proposes to amend Operating License NPF-43 for the Fermi 2 plant by incorporating ,

the enclosed change into Technical Specification 3/4.3.7.12 l Radioactive Gaseous Effluent Monitoring Instruneutation. The proposed change deletes the Standby Gas Treatment System effluent system flow rate monitor denoted in Table 3.3.7.12-1 to be consistent with the surveillance requirements denoted in Table 4.3.7.12-1 and the design of the plant.

Detroit B31 son has evaluated the proposed Technical Specifications against the criteria of 10CFR50.92 and determined that no significant hazards consideration is involved. The Fermi 2 Onsite Review Organization has approved and the ibclear Safety Review Group has reviewed these proposed Technical Specification changes and corcurs with the enclosed determinations.

Pursuant to 10CPR170.12(c), enclosed with this amerdment is a check for one hundred fifty dollars ($150.00) . In accordance with 10CFR50.91, Detroit B31 son has provided a copy of this letter to the ,

State of Michigan. j l

If you have any questions, please contact Mr. Lewis Bregni at (313) 586-4072.

/f- BMXGHarDD/DT93/.f , 7 1 y Technical Specification 3/4.3.7.12 -- Radioactive Gaseous Effluent #

Monitoping Instrumentation, hbh 3.3.7.12-1, currently denotes a I Standby Gas Treatment System (S71"S) Effluent System Flow Rate Monitor (Item 3.d) The propcised change will delete this item from Table 3.3.7.12-1 to be cord stent with the corresponding surveillance e requirements contained in Table 4.3.7.12-1 and the design of the plant. i j

On September 25,4HiJ, Detroit nilson identified a cordition where j Table 3.3.7.12-1,'Jten i.d, pequiring one operable effluent system j flow rate monitor chava pei division of SGTS, ha3 no associated {

surveillance requimment..in %ble 4.3.7.12-1. The subsequent I investigation revedlaf that all flow rate monitors ha3 been deletcd  !

from the Fermi 2 %chnical Specification prior to the issuance of the d Facility Operating License in Jdly 1985 except for Item 3.d which ,

I erroneously remainedm a 'line item in Table 3.3.7.12-1. '

l As discussed in Technical Specification Bases 3/4.3.7.12, the radioactive gaseous. effluent r.onitoring instrumentation is provided to ,

, , monitor and control, as applicable, the release of ra31oactive I materials in gaseous effluents during actual or potential releases of gaseous effluents. The alarvtrip setpoints for these ra3ioactiv2f ,

gaseous effluent monitoring instruments are calculated and :djusts in accordance with the methodology and parameters in the Offsite Dose l Calculation Manual (CDCM) . As specified in the CDCM, these alardtrip

.i y

setpoints are derived based on the maxinum design flovntes of the .

system rather thrJn using measured flow rates. Ascuming maxinum system, j flow is.a moreppservative method for calculative alarWtrip ,

setpoints that wisures the alardtrip will occur prij to exceeding <

the limits of '10TR Part 20. Although the SGTS design contEins flow j

f rate monitors', these[110w rates are not used in the determination of  !

alarWtrip setpointa an.3 thus th6se flow rate monitors were deletcd from the Technical Specification. During the develornen! and / crud ee L ,. 'M the Ferni 2 Pchnical Specifications, Item 3.d in Tabid 3.3.7.12-1

" y' , should have beenMnc7ed when other system flow rate mo:ffif rs were, removtd. As a' reault, this was an editorial error in the Technical i f Specifications 3rd 13 such Detroit Edison proposes to delete this h,em l consistent with the corrspording surveillance requirement ard '

the design of the plant.' . ,,

establish that operation in ecordance with the proposed amendment would not: 1) involve a significant increase in the probability or consequences of an accident previously evaluatM, or 2) create the l r

possibility of a new or different kind of accident from any accident j v '

previoutdy evaluatM, or, 3) involve a significant reduction in a )

margin of safety, ' J

1) The prqxised ch'ange to delete the refererce to the SGTS flow rate 1 monitor, Item 3.d, from Table 3.3.7.12-1 does not involve a 1 o significant increase in the probability or consequences of an accident previously evaluated. This change involves the correction of an editorial error in Table 3.3.7.12-1 which

' ~ identified a ErfS flow rate nonitor. All flow rate monitors and corresponding surveillance wre deleted from the Technical ,

. Spy:ifications prior to the issuance of the Facility Operating l Licenn in July 1985 except for Item 3.d which renained as a line )

item in Table 3.3.7.12-1. The flow rate monf tors are not used in  !

• the,determinatica of alarn/ trip setpoints. The change corrects an l

' editorial error that,is cordistent with both the surveillance l rc<pirements denotcd in Table 4.3.7.12-1 and the design of the '

. plan % and is censidered not to involve a significant hazards coasfacration. Au such, the change meets Example (i) of

( aneadmenty that are considered not likely to involve Significant Bazards Consideration (51 FR 7751) . In a3dition, the change does l

1. not result in any modifications to the plant or system operation {

and no safety-related equipnent or function will be altered. l I

2) The troposed change to delete the reference to the SGTS flow rate '

nonitor, Item l3.d, from Table 3.3.7.12-1 does not create the possibility of a new or different kind of accident from any accident previously evaluated. As in 1) above, this is a correction of an editorial error that is consistent with both the i surveilleence requirements denoted in Table 4.3.7.12-1 and the a design of the plant. There changes do not result in any modification to the plant or system operation and no safety-related equipnent c function will be altered. The requested change does not create any new accident mode.

i 3)- The proposed change to delete the reference to the SGTS flow rate i monitor, Item 3.d, from Table 3.3.7.12-1 does not involve a significant reduction in a margin of safety. As stated ir 1) above, this is a correction of an editorial error that is consistent with both the surveillance requirements denoted in Table 4.3.7.12-1 ard the design of the plant.

l Enclosure to i imC-87-0217 Page 3 Based upon the above reasoning, Detroit Mison has determined that the proposed anendnent does not involve a significant hazards consideration.

EWIRut@UNRL IMPACT Detroit Mison has reviewed the proposed Technical Specification changes against t.he criteria of 10CFR51.22 for environmental considerations. As shown above, the proposed change does not involve a significant hazards consideration, nor significantly change the j types or significantly increase the amounts of effluents that may be released offsite, nor significantly increase individual or cunulative occupational radiation exposures. Based on the foregoing, Detroit Edison concludes that the proposed Technical Specifications do neet t the criteria given in 1(X7R51.22(c)(9) for a categorical exclusion from the requirement for an Environmental Inpact Statement.

COELUSION Based on the evaluations above: (1) there is reasonable assurance that the health and safety of the public will not be endangered by operation in the' proposed manner, anS (2) such activities will be corducted in conpliance with the Commission's regulations and proposed ..

anerdnents will not be inimical to the common defense and security or j to the health and safety of the public.

The changes requested herein corrects an error in Table 3.3.7.12-1 consistent with both the surveillance requirements denoted in Table 4.3.7.12-1 and the design of the plant and as such is like that of I Example (i) of anendnents that are considered not likely to involve Significant Hazards Considerations (51 FR 7751) . l l
