y (TS) for the Fort Calhoun Station, Unit 1.
The pro)osed changes incorporate clarification to the operating modes by including tie operating mode numbers.
In addition, the licensee proposed that when the core is off-loaded during a-L Refueling Shutdown mode where there is no fuel in the core, testing required during this mode is not required.
2.0 EVALUATION The licensee's proposed changes to Table 3-4 of the TS are administrative in nature. The. addition of the Operating Mode numbers clarifies the modes and make them consistent with TS definition. ?resently. Table 3-4 of the TS re uires reactor-coolant sampling and ane.*1ysis during the following conditions:
1 (a Power Operation, (b) Hot Standby and Hot Shutdown, (c) Cold Shutdown, and (d Refueling Operation.- Refueling Operation, by TS definition, refers only to actual fuel movement. Therefore, the licensee is changing the wording of this mode to encompass the condition whereby the core has been off-loaded and re. naming this mode. Refueling Shutdown. By' TS definition, Refueling Shutdown mode:is where the reactor-is at refueling boron concentration and-water -
temperature is less than 210'F.
In addition the licensee is incorporating
'into Table 3-4 that when the core is off-loaded, boron and chloride sampling are not required since no fuel is present in the core. The basis for boron y
sampling is to ensure adequate shutdown margin for all core configuration when fuel is located in the core; and for' chloride, to ensure the prevention of chloride stress corrosion cracking of the fuel in the core. Since there is l
.no fuel:in the core during'the off-loaded condition, this sampling is not warranted..The staff finds that the above changes are appropriate and acceptable.
3.0 ENVIRONMENTAL CONSIDERATION
The amendment involves a change in a requirement with respect to the installation or use of a' facility component located within the restricted areat as defined in 10. CFR Part 20 and changes in surveillance requirements.
The staff has determined'that the amendment involves no significant increase in'the amounts, and no significant change in the types, of any effluents that may be released offsite, and that there is no significant increase in-individual or cumulative occupational radiation exposures.
- The Connissicn has: previcusly. issued a proposed finding -that the amendment j

. involves no significant hazards consideration and there has been ne public comment on.such finding. Accordingly, the amendment meets the eligibility criteriaforcategoricalexclusionsetforthin10CFRSection51.22(c)(9).
Pursuant to 10 CFR 51.22(b), no environmental impact statement or environ-mental assessment need be prepared in connection with the issuance of the arendment.
4.0 CONCLUSION
The staff has concluded, based on the considerations discussed above, that:
(1) there is reasonable assurance that the health and safety of the willnetbeendangeredbyoperationintheproposedmanner,and(2)public such activities will be conducted in compliance with the Commission's regulations, and the issuance of the amendment will bot be inimical to the common defense and security or to the health and safety of the public.
