The single limit is I 00/E-Bar in all 3 affected STS NUREGs. There are two places on this page that refer to limits (plural). This page should refer to limit (singular).
- 2. 71 FR 67172, Model SE, Section 2.0: Correct the title of TID 14844. "Reactor" is singular in the title.3.* 71 FR 67173, Model SE Section 3. 1. 1: The list of Dose Conversion Factor (DCF) references should be bracketed since this change will be subject to plant-specific considerations.
The optional DCF reference included in TSTF-490, and discussed in the traveler's justification section 3.0 (paragraph 2, lines 4-9), for alternate source term plants should be included here as follows: or [Committed Dose Equivalent (CDE) -or Committed Effective-Dose Equivalent (CEDE) dose conversion factors from Table 2.1 of EPA Federal Guidance Report No. 11.]1" 4. 71 FR 67173, Model SE Section 3.1.2: All noble gas isotope lists and DCF citations should be bracketed since these changes are subject to plant-specific considerations. The 2nd paragraph is missing a forward slash mark between the words "and' and "or" in the text "by tritium and corrosion and or activation products ....".5. 71 FR 67174, Model SE, Section 3. 1.33: The discussion on revised Required Action A.1I should be relocated to Model SE Section 3.1.5 that discusses the changes to TS 3.4.16 Condition A.S z) 6~J2 ;$e~ Kio-a subsidiary of Aneren Corporation 6. 71 FR 67174, Model SE Section 3.1.6: This section states that Condition "C" is replaced with a new Condition "B."' This is only true for the B&W and CE STS NUREGs (1430 and 1432). It is not true for the Westinghouse STS NUREG- 143 1, and it should be noted that the Westinghouse plants developed this traveler for submittal to the NRC. This section should state that "TS 3.4.16 Condition B [in NUJREG-143 1; C in NUREG-1430 and NUREG-1432] is replaced with a new Condition B for DEX not within limits." Model SE Section 3.1.6 should also discuss the addition of the LCO 3.0.4.c Note to revised Required.Action B. 1, consistent with the Model Application, Enclosure 1, Section 2.0, item C on 71 FR 67172.Suggested wording that could be used for this purpose is as follows: "A Note is also added to the revised Required Action B. I that states LCO 3 .0.4.c is applicable. This Note would allow entry into a Mode or other specified condition in the LCO Applicability when LCO 3.4.16 is not being met and is the same Note that is currently stated for Required Actions A. I and A.2. The proposed Note would allow entry into the applicable Modes when the DEX is not within its limit; in other words, the plant could go up in the Modes from Mode 4 to Mode 1 (power operation) while the DEX limit is exceeded and the DEX is being restored to within its limit. This Mode change allowance is acceptable due to the significant conservatism incorporated into the DEX specific activity limit, the low probability of an event occurring which is limiting due to exceeding the DEX specific activity limit, and the ability to restore transient specific activity excursions while the plant remains at, or proceeds to, power operation." 7. 71 FR 67174, Model SE, Section 3.1.8: This section incorrectly states that revised SR 3.4.16.1 has a new LCO 3.0.4.c Note. It should state that SR 3.4.16.1 has a new performance modifying Note that reads: "Only required to be performed in MODE 1L" The application of this style of Note is discussed in Example .1.4-5 in the latest revision of the STS NIJREGs. The LCO 3.0.4.c Note addition applies only to revised Required Action B. 1.The attached markups indicate where the above comments should be factored into the CLIII'Notice for Comment.

ACTION: Request for comment.
SUMMARY
- Notice is hereby given that the staff of the U.S. Nuclear Regulatory Commission (NRC) has prepared a model license amendment request (LAR], model safety evaluation (SE). and model proposed no significant hazards consideration (NSHC) determination related to deletion of E Bar (average disintegration energy. 2) definition and revision to reactor coolant system (RCS)specific activity technical specification.
This request revises the RCS specific activity specification for pressurized water reactors to utilize a new indicator, Dose Equivalent Xenon-133 instead of the current indicator known as E Bar.The purpose of these models is to permit the NRC to efficiently process amendments to incorporate these changes into plant-specific Technical Specifications (TS) for Babcock and Wilcox, Westinghouse, and Combustion Engineering Pressurized Water Reactors (PWRs). Licensees of nuclear power reactors to which the models apply can request amendments conforming to the models. In such a request, a licensee should confirm the applicability of the model LAR, model SE and NSHIC determination to its plant. The NRC staff is requesting comments on the model bAR, model SE and NSHC determination for referencing in license amendment applications. DATES: The comment period expires 30 days from the date of this publication. Comments received after this date will be considered if it is practical to do so.but the Commission is able to ensure consideration only for comments received on or before this date.ADDRESSES: Comments may be submitted either electronically or via U.S. mail.Submit written comments to: Chief.Rulemaking, Directives, and Editing Branch, Division of Administrative Services.

Background
Regulatory Issue Summary 2000-06,"Consolidated Line Item Improvement Process (CHIP) for Adopting Standard Technical Specifications Changes for Power Reactors." was issued on March 20, 2000. The CL[IP is intended to improve the efficiency and transparency of NRC licensing processes. This is accomplished by processing proposed Federal Register/Vol. 71, No. 223/Monday, November 20, 2006/Notices671 67171 changes to the Standard Technical Specifications (STS) in a manner that sup poils subsequent license amendment applications. The CLTIP includes an opportunity for the public to comment on proposed changes to the STS following a preliminary assessment by the NRC staff and finding that the change will likely be offered for adoption by licensees. This notice is soliciting comment on a proposed change to the STS that deletes the E Bar definition and revises the RCS specific activity technical specification of the Babcock and Wilcox PWvR STS, Revision 3 of NUREG-1430, Westinghouse PWR STS Revision 3 NUREG-1431, and Combustion Engineering PWR STS Revision 3 NUREC-1432. The CLlIP directs the NRC staff to evaluate any comments received for a proposed change to the STS and to either reconsider the change or proceed with announcing the availability of the change for proposed adoption by licensees. Those licensees opting to apply for the subject change to TSs are responsible for reviewing the staff's evaluation, referencing the applicable technical justifications, and providing any necessary plant-specific information. Following the public comment period, the model LAR and model SE will be finalized, and posted on the NRC webpage. Each amendment application made in response to the notice of availability will be processed and noticed in accordance wth applicable NRC rules and procedujes. Th~is notice involves rep acemt.t ofi the current PWR TS 3.4.16 lim! )n RCS gross specific activity with new limit on RCS noble gas specific activity.The noble gas specific activity limit would be based on a new dose equivalent Xe-133 (DEX) definition that would replace the current E-Bar average disintegration energy definition. In addition, the current dose equivalent I-131 (DEl) definition would be revised to allow the use of additional thyroid dose conversion factors (DCFs). By letter dated September 13, 2005, the Technical Specifications Task Force (TSTF) proposed these changes for incorporation into the STS as TSTF-490, Revision 0.Applicability
- These proposed changes will revise the definition of DOSE EQUIVALENT I-131. delete the definition of "E-Bar," AVERAGE DISINTEGRATION ENERGY, add a new definition for DOSE EQUIVALENT XE-133, and revise LCO 3.4.16 for Babcock and Wilcox, Westinghouse.
and Combustion Engineering PWRs, STS NUREGs 1430.1431. and 1432.To efficiently process the incoming license amendment applications, the NRC staff requests that each licensee applying for the changes addressed by TSTF-490, Revision 0, using the CLUIP submit an LAR that adheres to the following model. Any variations from the model LA.R should be explained in the licensee's submittal. Variations from the approach recommended in this notice may require additional review by the NRC staff, and may increase the time and resources needed for the review.Significant variations from the approach. or inclusion of additional amendment requests, may result in staff rejection of the CLUI adoption request.Instead, licensees desiring significant variations and/or additional changes should submit a non-CLIIP LAR that does not request to edopt TSTF-490 via CLI1P.Public Notices This notice requests comments from interested members of the public within 30 days of the date of this publication. Following the NRC staff's evaluation of comments received as a result of this notice, the NRC staff may reconsider the proposed change or may proceed with announcing the availability of the change in a subsequent notice (perhaps with some changes to the model LAR,'Model SE or model NSHC determination as a result of public comments). If the NRC staff announces the availability of the change. licensees wishing to adopt the change will submit an application in accordance with applicable rules and other regulatory requirements. The NRC staff will, in turn, issue for each application a notice of consideration of issuance of amendment to facility operating license(s), a proposed NSHC determination, and an opportunity for a hearing. A notice of issuance of an amendment to operating license will announce the revised requirements for each plant that applies for and receives the requested change.Dated at Rockville. Maryland this 14th day of November. 2006.For the Nuclear Regulatory Commission. Timothy J. Kobetz.Chief. Technical Specifications Branch, Division of Inspection and Regional Support, Office of Nuclear Reactor Regulation. For inclusion on the technical specification web page. The following example of an application was prepared by the NRC staff to facilitate the adoption of Technical Specifications task force (TSTF) Traveler TSTF-490. Revision 0 "deletion of E-bar definition and revision to RCS Specific Activity Tech Spec." The model provides the expected level of detail and content for an application to adopt TSTF-490. Revision 0.Licensees remain responsible for ensuring that their actual application fulfills their administrative requirements as well as NRC regulations.

[For Licensees using the TID 14844 source term, the maximum dose criteria to the whole body and the thyroid that an individual at the exclusion area boundary (EAB) can receive for the first 2 hours following an accident, and at the low population zone (LPZ) outer boundary for the duration of the radiological release, are specified in Title 10 of the Code of Federal Regulations (10 CFR) Part 100. 11. These criteria are 25 roentgen equivalent man (rem)total whole body dose and 300 rem thyroid dose from iodine exposure. The accident dose criteria in 10 CFR 100.11 is supplemented by accident specific dose acceptance criteria in SRP 15.1.5.

GDC 19 requires that adequate radiation protection be provided to permit access and occupancy of the control room under accident conditions without personnel receiving radiation exposures in excess of 5 rem whole body, or its equivalent to any part of the body, for the duration of the accident. NUREC-0800. SRP Section 6.4, "Control Room Habitability System," Revision 2, July 1981, provides guidelines defining the dose equivalency of 5 rem whole body as 30 rem for both the thyroid and skin dose. For licensees adopting the guidance from RG 1.196, "Control Room Habitability at Light Water Nuclear Power Reactors," May 2003, Section C.4.5 of RG 1.195, May 2003, states that in lieu of the dose equivalency guidelines from Section 6.4 of NUREG-OBOG, the 10 CFR 20.12 01 annual organ dose limit of 50 rem can be used for both the thyroid and skin dose equivalent of 5 rem whole body.][Licensees using the AST are evaluated against the dose criteria specified in 10 CFR Part 50.67. The off-site dose criteria are 25 rem total effective dose equivalent (TEDE) at the EAB for any 2-hour period following the onset of the postulated fission product release and 25 rem TEDE at the outer boundary of the LPZ for the duration of the postulated fission product release. in addition, 10 CFR Part 50.67 requires that adequate radiation protection be provided to permit access and occupancy of the control room under accident conditions without analyses become disconnected from plant personnel receiving radiation exposures in operation and the limiting condition for excess of 5 rem TEDE for the duration of the operation (LCO) becomes essentially accident.] meaningless.

4.0 STATE CONSULTATION
In accordance with the Commission'.s regulations, the [i State official was notified of the proposed issuance of the amendment. The State official had 0)1 no comments or (2)the following comments-with subsequent disposition by the staff].5.0 ENVIRONMENTAL CONSIDERATION The amendmnentisl changelsi a requirentent with respect to the installation or use of a facility component located within the restricted area as dofined in 10 CFR Part 20 or surveillance requirements. The NRC 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 the amendment involves no signi ficant hazards consideration and there has been no public comment on such finding published [DATE]([I JFR IIJ). Accordingly, the amendment meets the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(9). Pursuant to 10 CFR 51.22(b). no environmental impact statement or environmental assessment need be prepared in connection with the issuance of the amendment.
6.0 CONCLUSION
The Commission hans concluded, based on the considerations discussed above, that (11 there is reasonable assurance that the health and safety of the public wilt not be endangered by operation in the proposed manner. (2) such activities will be conducted in compliance with the Commission's regulations, and (3) the issuance of the amendment will not be inimical to the common defense and security or to the health and safety of the public.Proposed No Significant Hazards Consideration Detertmination Description of Amendment Request:[LICENSEE) requests adoption of an approved Change to the standard technical specifications (STS) for Pressurized Water Reactor (PWR) Plants [NUREG-143o, NUREG-1431. or NUJREG-14321 and the[LICENSEE] technical specifications (TS), to replace the current limits on primary coolant gross specific activity with limits on primary coolant noble gas activity. The noble gas activity would be based on DOSE EQUIVALENT XE-1 33 and would take into account only the noble gas activity in the primary coolant. The changes are consistent with NRC approved Industry/Technical Specification Task Force (TSTF) Standard Technical Specification Change Traveler, TSTF-490.Basis for proposed no-significont-hazt-rds-consideration determination: As required by 10 CFR 50.91 (a). an analysis of the issue of no-significant-hazards-consideration is presented below: Criterion I-The Proposed Change Does Not Involve a Significant Increase in the Probability or Consequences of on Accident Previously Evaluated Reactor coolant specific activity is not an initiator for any accident previously evaluated. The Completion Time when primary coolant gross activity is not within limit is not an initiator for any accident previously evaluated. The current variable limit on primary coolant iodine concentration is not an initiator to any accident previously evaluated. As a result.the proposed change does not significantly increase the probability of an accident. The proposed change will limit primary coolant noble gases to concentrations consistent with the accident analyses. The proposed change to the Completion Time has no impact on the consequences of any design basis accident since the consequences of an accident during the extended Completion Time are the same as the consequences of an accident d uring the Completion Time. As a result, the consequences of any accident previously evaluated are not significantly increased. Criterion 2-The Proposed Change Does Not Create the Possibility of a New or Different Kind of Accident fromt any Previously Evaluated The proposed change in specific activity limits does not alter any physical part of the plant nor does it affect any plant operating parameter. The change does not create the potential for a new or different kind of accident from any previously calculated. Criterion 3-The Proposed Change Does Not Involve a Significant Reduction in the Margin of Safety The proposed change revises the limits on noble gase radioactivity in the primary coolant. The proposed change is consistent with the assumptions in the safety analyses and will ensure the monitored values protect the initial assumptions in the safety analyses.Based upon the reasoning presented above and the previous discussion of the amendment request, the requested change does not involve a significant hazards consideration.
