SAFETY EVALUATION BY THE OFFICE OF NUCLEAR REACTOR REGULATION SUPPORTING AMENDMENT NO. 39 TO FACILITY OPERATING LICENSE NO. DPR-22 NORTHERN STATES POWER COMPANY MONTICELLO NUCLEAR GENERATING PLANT DOCKET NO. 50-263

1.0 INTRODUCTION

By letter dated April 26, 1985, and as supplemented on October 16, 1985, Northern States Power Company (NSP, the licenseel proposed to change the Technical Specifications (TS) to incorporate the recommendations of Generic Letter 84-13, to satisfy a previous comitment and to incorporate miscellaneous administrative changes. The changes were as follows:

1.

Snubber Table. Delete Table 3.6.1 and all references to Table 3.6.1 from pages vi, 129, 130, 131 and 132. Delete paragraph 3.6.H.3.

The proposed changes implement the recommendations of Generic Letter 84-13 dated May 3, 1984.

In paragraph 4.6.H.2, change "impared" to " impaired."

2.

Section 6.5.G, Plant Operating Procedures - Temporary Changes to Procedures. Delete the requirements for the Operations Comittee to review the temporary chanaes to non-safety-related health physics and security procedures.

3.

Section 6.5.B, Plant Operating Procedures - Radiological. The phrase "and concise statement" is replaced bv " definition" to clarify the Radiation Protection Plan. The Monticello Radiation Protection Program and policy is defined in the Plant Administrative Control Directives (ACDs), consistent with the requirements of 10 CFR Part 20.

4 Rod Block Monitor (RBM).

In Table 4.2.1, increase the RBM surveillancetestfrequencytooncepermonthfromgnceper3 months for exposure hours (M) greater than 2.0 x 10. The licensee had committed to this change in its letter of October 17, 1984.

5.

Section 4.16, Radiation Environmental Monitoring Program.

In Table 4.15.1 (page 5 of 5), corn and potato environmental radiation samplina will be limited to the areas that are irrigated by water in which liquid radioactive effluent has been discharged.

6.

Miscellaneous Administrative Changes.

a)

Page 229i. Correct references in TS 4.16.A.4.

8603190417 860313 DR ADOCK 05000263 PDR

. b)

Pages 229q and 229r.

Clarify notes "d" and "e" to specify the radionuclides (s) to which the low level dos'es (LLDs) are acceptable.

c)

Page 244. Correct drill frequency referenced in procedures from A.6 to A.S.

d)

Page 244a. Correct typographical errors.

7.

I-131 Reportability.

In Table 4.16.3, a footnote C is added to clarify the I-131 reportability requirements in environmental samples.

2.0 EVALUATION Item No. I above implements the recommendations of Generic Letter (GL) 84-13 dated May 3, 1984.

It provides an option to eliminate snubber listings within the TS provided the snubber TS are modified to specify which snubbers are required to be operable. The recordkeeping require-ments of snubbers TS are not altered by this recommendation. The change requested in Item No. I does not alter any TS requirements such as snubber quantities, types, or locations.

It only eliminates Table 3.6.1 and all references to this table. The staff has reviewed the licensee's proposed changes and concludes that they are in conformance with the guidance provided in GL 84-13 and therefore, are acceptable.

Item No. 2 above deletes the requirements for the Operations Committee to review the temporary changes to non-safety-related health physics and security procedures.

In letters' dated September 24, 1982 and March 30, 1984, the licensee requested elimination of Operations Committee review of non-safety-related procedures performed by health physics and guard force personnel. This was approved by the staff in Amendment No. 25 dated August 15, 1984. Technical Specification 6.5.G requires Operations Committee review of the temporary changes to procedures. The Operations Committee should not be required to review temporary changes to procedures covering health physics or cuard force functions that did not require Operations Committee review when issued.

The licensee further states that this review procedure will be omitted only for non-safety-related procedures associated with the activities performed exclusively by health physics or security personnel. The NRC staff has reviewed the licensee's submittal and concludes that the proposed change is acceptable.

Items 3, 5, 6 and 7 above modify portions of the licensee's Radiological Effluent Technical Specifications (RETS). Changes proposed in Items 3, 6, and 7 are strictly administrative in nature and incorporate clarifications contained in the NRC TS guidance for environmental monitoring developed since the issuance of Amendment No. 15. The staff has reviewed the licensee's proposed chances and concludes that these changes do not affect the technical content of the TS and as stated they meet the intent of the NRC model RETS for boiling water reactors (BWRs), NUREG-0743, Revision 2, February 1,1980 and are, therefore, acceptable.

. Item No. 5 above modifies the requirement for potato and corn environmental radiation sampling. Over the period of several years, a uniform process of deep well irrigation has been developed in the area and the use of river water for irrigating potato and corn fields has been discontinued. The collection of potato and corn samples is no longer a valid monitor to determine the impact of liquid release of radioactivity into the river. The land use census specified in the TS does not identify high D/Q corn and potato locations. Leafy green vegetable samples from a garden in the highest D/Q sector are used to determine radioisotope buildup due to air release from the plant.

The sampling of corn and potatoes will be continued but limited to areas that are irrigated by water in which liquid radioactive effluents have been discharged. This change is due to a shift in land use in the vicinity of the plant.

In addition, the licensee has agreed to revise Section 5.1 cf the Off-site Dose Calculations Manual (0DCM).

Revised ODCM Section 5.1 will include, "If the plant begins routine discharges of liquid radioactive effluent into the Mississippi River, a land use survey will be conducted to determine whether any crops are irrigated with water taken from the Mississippi River between the plant discharge canal and a point 5 miles downstream.

If edible crops are being irrigated from Mississippi River water, appropriate samples will be collected and analyzed per Technical Specification Table 4.15.1".

The staff has reviewed the licensee's proposed changes to the require-ment for potato and corn environmental radiation sampling and to Section 5.1 of the ODCM. These changes meet the intent of the NRC model RETS for BWRs, NUREG-0673, Revision 2 and are, therefore, acceptable.

In Item No. 4, the licensee proposes to increase the RBM test frequency as shown in Table 4.2.1 of the TS from once per 3 gonths to once per month for exposure hours (M) greater than 2.0 x 10. This change satisfies the commitment made by the licensee in its letter dated October 17,1984, " Supplementary Information Related to License Amendment Request dated May 30, 1984, ARTS". The staff had reviewed this item at that time and found this change to be acceptable.

3.0 ENVIRONMENTAL CONSIDERATION

This amendment involves changes to requirements with respect to the installation or use of facility components located within the restricted area as defined in 10 CFR Part 20, changes to the surveillance requirements, and changes in recordkeeping, reporting, and administrative procedures and 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 exposure, The Commission has previously issued a proposed finding that this amendment involves no significant hazards consideration and there i

. has been no public comment on such finding. Accordingly, this emandment meets the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(9) and (10). Pursuant to 10 CFR 51.22(b) no environmental impact statement nor environmental assessment need be prepared in connection with the issuance of this amendment.

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 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 nor to the health and safety of the public.
