1.0 INTRODUCTION
i By letter cated December 9, 1987, Alabama Power Company (APCo) submitted a request for changes to the Joseph M. Farley Nuclear Plant, Units 1 and 2 Technical Specifications (TS).
The proposed amendments would change TS 6.9.1.9 to amend the Semiannual Radioactive Effluent Release Report requirements to allow the use of historical annual average meteorological data to determine the gaseous pathway doses due to the routine release of radioactive gaseous effluents.
This is an option that is provided for in NUREG-0133 and is censistent with the TS Bases and the Final Safety Analysis Report.
An acministrative correction to the spelling of the word "or" would also be made in the same paragraph, a
2.0 EVALUATION Routine radtoactive release reports are required semiannually by T.S.
6.9.1.8.
The release report submitted to the NRC after January 1 of each year includes an assessment of the radiation coses due to radioactive gaseous effluents released from the unit during the previous calencar year. The existing TS 6.9.1.9 requires the use of the reteorological conditions concurrent with the time of release of L
radioactive raterials in gaseous effluents to calculate the gaseous path-
[
way doses. The assessment of radiation doses are perforred in accordance with the Offsite Dose Calculation Manual (00CM).
Gaseous releases which could affect the public health and safety are 7
maintained within acceptable limits through the use of Limiting Conditions for Operations (LCO) included in TS 3.11.2, Gaseous Effluents.
These TSs incluce dose rate calculational limits as well as gaseous radwaste treattert systems operability requirements.
The Itcensee's proposed changes to TS 6.9.1.9 relate only to reporting requirements used for record purposes and do not affect the LCO requirements or safety actions in any way, in addition, as APCo has stated, the existing 00CM 8803140031 000308 DR ADOCK 05000340 PDR
s o l
for the Farley Nuclear Plant contains Comission approveo methodology for calculating the doses from gaseous releases.
This methodology is based on historical average atmospheric conditions.
APCo states that the proposed change is consistent with Standard Review Plan (SRP), hUREG-0800.
Paragraph III.4 of Section 2.3.5 of the SRP notes that the hRC staff will use annual relative concentratiun (X/Q) and relative disposition (0/Q) values in assessment of the consequences of routine airborne radioactive releases.
The proposed change is consistent with the SRP methodology, in addition to the SRP, noted above, NUREG-0133, "Preparation of Radiological Effluent Technical Specifications for huclear Power Plants,"
Sections 3.3, 5.2.1, and 5.3.1 note that the use of historical annual average meteorological conditions are acceptable for calculating coses due to routine gaseous effluent releases.
Regulatory Guide (RG) 1.1.1, as well as huREG-0133, provides guidance which could be used by licensees, depending on the meterological conditions, in calculational models.
In some cases the annual average conditions may be used and in other cases time of release conditions should be used.
Further guidance is provided in NUREG-0324 for making a determination of doses due to short term releases, if such releases are sufficiently random in both time of day and duration. ApCo states that historical release data from Farley demonstrate that the routine, operational short-term releases (i.e.,
less then 500 hours0.00579 days <br />0.139 hours <br />8.267196e-4 weeks <br />1.9025e-4 months <br /> per quarter) meet NUREG-0133 criteria of being random in time of day eno duration.
Subsequent verification of this statement will be made curing the normal on-site radiological inspections conducted by regional inspectors.

The licensee has proposed additional flexibility to TS 6.9.1.9 to allow I
using historical annual average reteorology or the meteorological condi-l tions concurrent with the time of release.
Thus, the proposed change is consistent with existing hRC staff guidance. Also, the radiation dose rate calculations would be cone in accordance with the NRC approved ODCM.
The spelling of the word "or" in the same paragraph is an administrdtive correction. Therefore, the proposed TS changes are acceptable.
3.0 ENVIR0hMEhTAL CONS!0ERATION These amendments change recordkeeping, reporting, or administrative procedures or requirements.
The Comission has previously issued a proposed finding that these amendments involve no significant hazards consideratton, and there has been no public coment on such finding.
Accordingly, these amendments meet the eligibility criteria for i
i
b,
categorical exclusion as set forth in 10 CFR 51.22(c)(10). Pursuant to 10 CFR 51.22(b) no environmental impact statement or environmental assessment need be prepared in connection with the issuance of these amendments.
4.0 CONCLUSION
The Commission made a proposed determination that this amendment involves no significant hazards consideration which was published in the _ Federal Register on December 30, 1987 (52 FR 49219), and consulted with the State of Alabama.
No public coments or requests for hearing were received, and the State of Alabama did not have any coments.
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 these amendments will not be inimical to the common defense ano security or to the health and safety of the public.
