INTRODUCTION By applications for license amendments dated September ?.4,1987 and November 2, 1987, Northeast Nuclear Energy Company, et al. and Connecticut Yankee Atomic Power Company requested changes to the Technical Specifications (TS) for Haddam Neck ar.d Millstore Units 1, 2 and 3 as follows:

(1) TS 6.5.3.9.b (TS 6.5.P.9.b for Haddam Neck), "Records," would be modified to identify the Nuclear Review Board (NRB) minutes as an acceptable means to forward certair reports to the Senior Vice President, Nuclear Engineering and Operations, (2) a maximum of 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> of continuous planned inoperability for liquid and gaseous effluent monitoring instrumentation would be permitted (Millstone Unit 2 only),

(3) inoperability of liquid and gaseous effluent monitoring instruments for the parpose of obtaining samples, would be pennitted (Millstone Unit 2 only), (4) a period of 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> within which auxiliary sampling of radioactive gaseous effluent must be initiated if the established minimum number of effluent monitoring channels become inoperable would be established (Millstone Unit 2 only.)

DISCUSSION AND EVALUATION Haddam N_e,ck,,, Millstone Units 1, ? and 3 At the present time, TS 6.5.3.9 b (TS 6.5 ?.9.b for Haddam Neck) requires that reports of Nuclear Review Board (NRB) reviews be prepared, approved and forwarded to the Senior Vice President Nuclear Engineering and Operations within 14 days following completion of the reviews. The requirements of TS 6.5.3.9.b are not specific as to the form of the report. The licensee has proposed to add a clarification as to one acceptable form of NRB report in that, NRB meeting minutes may be used for this purpose.

The proposed changes to TS 6.5.3.9.b (TS 6.5.?.9.b for Haddam Neck) would only effect the TS in that an acceptable vehicle for NRB reporting (NRB minutesl would be specified in the TS. Accordingly, the proposed change to the TS is acceptable.

Millstone Unit 2 Technical Specifications 3.3.3.9, "Radioactive Liquid Effluent Fonitoririg Instrunentation", and 3.3.3.10. "Radioactive Gaseous Effluent Monitoring Ir.strumentation" provide Limiting Conditions for Operation end reredial actier.

requirener.ts for the subject instrumentation. At the present time TS 3.3.3.0 and 10 allow gaseous and liquid effluent nonitoring instrunents to be n,ade increrable for an unspecified period of tine within the 30 day action period for the purpose of perforn.ing preplanned activities. The TS defines these preplanned activities as "...e.aintenance and perforn.ance of required tests checks and calibration." The licensee has proposed a change to TS 3.3.3.9 and 10 to specify 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> as the allcwatle instrur+nt outage time, for perfomance of preplanned activities, ar.d to extend the definition of the preplanned activities to include "sarpling."

The licensee has preposed an additional change to TS 3.3.3.10 which presently requires that sarpling of radioactive gaseous effluent pathways be undertaken if the minitum specified nunber of the associated n.onitoring channels becone inoperatie.

The licensee has proposed that such tronitoring begin within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> of tin 4 that the ronitoring channels are detemined to he inoperable.

The proposed changes to TS 3.3.3.9 and 3.3.3.10 represent clarification cf existing requirener.ts.

In the case of the I? hour period for planned inoperability of the effluent monitoring channels, and the I? hour period for initiating sanpling when the gaseous effluent ponitoring channels are inoperable, these periods had not been previously defined in the TS. These !?

hour periods are judged to be acceptable based upon the monitoring function of the instrenentation.

In the case of adding "sampling" as a pennitted, preplanned, instrunent outage activity. "sampling" is expected to account for a small fracticn (less than 10%) of total effluent monitoring instrunent outage tire and is thus, net significant in tems of overall equipment availability.

Based upon the above, the changes to TS 3.3.3.9 and 10 are acceptable.

EWIFONVENLALC0hSIDERAT10h The amendment for Millstone Unit 2 changes a requirernent with respect to irstellation or use of a facility component located within the restricted area as defined in 10 CFR Part 00. The amendments for Haddam Neck and Millstone Units 1, 2 and 3 involve changes which are edministrative in nature. The staff has detemined that the anendments involve nc significant increase in the amounts, and no significant change in the types, of any effluents that way be released effiste, and that there is no significant increase in individual or curulative occupational radiation exposure. The Cornission has previously published a proposed finding that the an.endnents involve no significant hazards consideration and there has been no public corrent on such finding.

Accordingly, the amendments nfet the eligibility criteria for categorial exclusionsetforthin10CFRiSI.22(c)(9)and(10). Pursuant to 10 CFR 551.22(b), no environnental irpact staternent or environmental assessrent need be prepared in connection with the issuance of the atendrents.

o

'C 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 amendments will not be inimical to the common defense and security or to the health and safety of the p0blic.
