1.0 INTRODUCTION
By letter dated July 29, 1993, Detroit Edison Company (the licensee),
submitted proposed changes to the Fermi Unit 2 Technical Specifications (TS) in support of its plan to implement the revised 10 CFR Part 20. The licensee inadvertently included a change in its proposed TS page 1-3 for the " LOGIC SYSTEM FUNCTIONAL TEST" definition. As discussed with the licensee's staff, l
- this was not meant to be included as part of this application and therefore, was not reviewed.
2.0 EVALUATION The licensee has revised the TS to include wording that is consistent with the revised 10 CFR Part 20, Standards for Protection Aaainst Radiation, and will retain the same overall level of effluent control required to meet the design objectives of Appendix I to 10 CFR Part 50.
The proposed TS changes and evaluations follow:
i 1.
Section 1.0 DEFINITIONS The licensee has proposed to revise the definitions of MEMBER (S) 0F THE
'i PUBLIC, and UNRESTRICTED AREA to conform to the definitions of these terms-4 used in 10 CFR 20.1003.
The staff has verified that the proposed definitions conform to the corresponding definitions in 10 CFR 20.1003 and considers these changes to be administrative in nature and acceptable.
j 2.
TS 6.8.5.e Radioactive Effluent Controls Proaram The licensee has. proposed to revise item 2 to replace the words
" Appendix B, Table II" with " Appendix B, Table 2."
Also, item 3 of this TS is being revised to replace the reference to "10 CFR 20.106" with "10 CFR 20.1302."
These changes are administrative in nature to incorporate the corresponding revised 10 CFR Part 20 section number and table number and are acceptable.

TS 6.8.5.e Radioactive Effluent Controls Proaram The licensee has proposed to revise item 2 of this TS which specifies the limitations on the concentrations of radioactive material released in liquid effluents to UNRESTRICTED AREAS. The licensee has proposed that the TS be revised to allow " ten times the concentration values in 10 CFR 20.1001 - 20.2401, Appendix B, Table 2, Column 2."
The licensee has proposed this change in order to retain operational flexibility consistent with Appendix I to 10 CFR Part 50, concurrent with the implementation of the revised 10 CFR Part 20. A typographical error in the reference to section 20.2401 has been corrected to read 20.2402.
The current requirements for the content of the licensee's TS concerning radioactive effluents are contained in 10 CFR 50.36a.
Section 50.36a of 10 CFR requires licensees to maintain control over radioactive material in gaseous and liquid effluents to unrestricted areas, produced during normal reactor operations, to levels that are as low as reasonably achievable (ALARA).
For power reactors, Appendix I to 10 CTR Part 50 contains the numerical guidance to meet the ALARA requirement. The dose values specified in Appendix I of 10 CFR Part 50 are small percentages of the implicit limits in 10 CFR 20.106 and the explicit limits in 10 CFR 20.1301. As secondary controls, the instantaneous dose rates required by this TS were' chosen by the staff to help maintain annual average releases of radioactive material in gaseous and liquid effluents to within the dose values specified in Appendix I of 10 CFR Part 50.
For the purposes of this TS,10 CFR Part 20 is used as a source of reference values only.
These TS requirements allow operational flexibility, compatible with considerations of health and safety, which may temporarily result in release rates which, if continued for the calendar quarter, would result in radiation doses higher than specified in Appendix I of 10 CFR Part 50.
However, these releases are within the implicit limits in 10 CFR 20.106 and the explicit limits in 10 CFR 20.1302 which references Appendix B, Table II concentrations. These referenced concentrations in the old 10 CFR Part 20 are specific values which relate to an annual dose of 500 mrem.
The liquid effluent radioactive effluent concentration limits given in Appendix B, Table 2, Column 2 to 10 CFR 20.1001 - 20.2402 are based on an annual dose of 50 mrem total effective dose equivalent. Since an instantaneous release concentration corresponding to a dose rate of 500 mrem / year has been acceptable as a TS limit for liquid effluents, which applies at all times to assure that the values in Appendix I of 10 CFR Part 50 are not likely to be exceeded, it is not necessary to reduce this limit by a factor of 10.
The licensee states that the use of effluent concentration values that are 10 times those listed in Appendix B, Table 2, Column 2 to 10 CFR 20.1001 -
20.2402 will not have a negative impact on the ability to continue to operate w; thin the design objectives in Appendix I to 10 CFR Part 50 and 40 CFR Part 190.
7.
Based on the a'bove, it is acceptable that the instantaneous limits associated with the liquid release rate TS are based on 10 times the effluent concentration values given in Appendix B, Table 2, Column 2 to 10 CFR 20.1001 - 20.2402, to apply at all times.
4.
TS 6.8.5.e Radioactive Effluent Controls Proaram The licensee has proposed to revise item 7 of this TS which specifies the limitations on the concentrations of radioactive material released in gaseous effluents. The licensee has proposed that the TS be revised to read as follows:
" Limitations on the dose rate resulting from radioactive material released in gaseous effluents from the site to areas at or beyond the SITE B0UNDARY shall be limited to the following:
a.
For noble gases:
less than or equal to 500 mrem /yr to the total body and less than or equal to 3000 mrem /yr to the skin, and b.
For Iodine-131, for Iodine-133, for tritium, and for all radionuclides in particulate form with half-lives greater than 8 days:
less than or equal to 1500 mrem /yr to any organ;"
The licensee has proposed this change in order to retain operational flexibility consistent with 10 CFR Part 50, Appendix I, concurrent with-the implementation of the revised 10 CFR Part 20.
The current requirements for the content of the licensee's TS concerning radioactive effluents are contained in 10 CFR 50.36a.
Section'50.36a of 10 CFR requires licensees to maintain control over radioactive material in gaseous and liquid effluents to unrestricted areas, produced during normal reactor operations, to ALARA levels.
For power reactors, Appendix 1 to 10 CFR Part 50 contains the numerical guidance to meet the ALARA requirement.
The dose values specified in Appendix I of 10 CFR Part 50 are small percentages of the implicit limits in 10 CFR 20.106 and the explicit limits in 10 CFR 20.1301. As secondary controls, the instantaneous dose rates required by this specification were chosen by the staff to help maintain annual average releases of radioactive material in gaseous and liquid effluents to within the dose values specified in Appendix I of 10 CFR Part 50.
For purpose of the bases of this TS, 10 CFR Part 20 is used as a source of reference values only. These TS requirements allow operational flexibility, compatible with considerations of health and safety, which may temporarily result in release rates which, if continued for the calendar quarter, would result in radiation doses higher than specified in Appendix I of 10 CFR Part 50. However, these releases are within the limits specified in 10 CFR 20.106 (10 CFR 20.1302).
This specification, which is based on guidance contained in NUREG-0133,
" Preparation of Radiological Effluent Technical Specifications for Nuclear Power Plants: A Guidance Manual for Users of Standard Technical Specifications," is acceptable as a TS limit for gaseous effluents, which
. applies at all times as an assurance that the values in Appendix I of 10 CFR Part 50 are not likely to be exceeded.
The licensee states that the proposed TS change will not have a negative impact on the ability to continue to operate within the design objectives in Appendix I of 10 CFR Part 50.
Based on the above, it is acceptable that the gaseous release rate TS for radioactive material be based on the stated dose rates.
5.
TS 6.9.1.5 ANNUAL REPORT,5 The licensee has proposed to revise this TS to indicate that the annual tabulation of individuals receiving greater than 100 mrem in a year includes only those individuals for whom monitoring was required.
The proposed c.hange is administrative in nature which provides clarification of the TS consistent with the requirements of the revised Part 20. The proposed change is acceptable.
6.
TS 6.9.1.5 ANNUAL REPORTS The licensee has proposed to revise this TS to replace the reference to "20.407" with "20.2206."
This change is administrative in nature to incorporate the corresponding revised 10 CFR Part 20 section number and is acceptable.
7.
TS 6.10 RECORD RETENTION The licensee has proposed to relocate TS 6.10.2.f to TS 6.10.3.o.
This change ensures that records of radioactive shipments are retained for the duration of the operating license.
This change is consistent with the requirements of the revised 10 CFR 20.2108(b) and is acceptable.
I 8.
TS 6.10 RECORD RETENTION The licensee has proposed to revise TS 6.10.3.c to require retention of dose records only for those individuals for whom monitoring was required.
This change is consistent with the requirements of the revised 10 CFR Part 20 and is acceptable.

TS 6.12 HIGH RADIATION AREA The licensee has proposed to revise TS 6.12.1 to replace the reference to "20.203(c)(2)" with "20.1601."
The licensee also proposes to change the term " health physics" to " radiation protection" to reflect Fermi 2 organizational groups.
The changes are administrative in nature and are consistent with the revised 10 CFR Part 20 and are acceptable.
- 10. TS 6.12 HIGH RADIATION AREA The licensee has proposed to revise the note in TS 6.12.2 to read
"* Measurements made at 30 cm from the sources of radioactivity." The licensee will replace the words "a major portion of the body" with "an individual. " The licensee has also proposed an upper limit for which the TS applies by adding the words "500 rads at one meter."
The changes are consistent with the revised 10 CFR Part 20 and are acceptable.
The licensee has proposed to revise TS 6.14.2.a.2 to replace the reference "10 CFR 20.106" with "10 CFR 20.1302."
This change is administrative in nature to incorporate the corresponding revised 10 CFR Part 20 section number and is acceptable.
- 12. BASES 3/4.11.1.4 LIOUID HOLDVP TANKS The licensee has proposed to revise the BASES to replace the reference to
" Appendix B, Table II" with " Appendix B, Table 2."
This change is administrative in nature to incorporate the corresponding revised 10 CFR Part 20 table number and is acceptable.
