Attachment 1 GNRO-2002/00030 Analysis of Proposed Technical Specification Change to GNRO-2002/00030 Page 1 of 8
1.0 DESCRIPTION
This letter is a request to amend Operating License NPF-29 for Grand Gulf Nuclear Station, Unit 1 (GGNS).
The proposed change will revise the Technical Specifications (TS) to correct or clarify certain requirements and information. Except for one technical change that corrects a limiting value, most of the proposed changes are administrative in nature. One of the changes is being proposed at NRC staff request as discussed in a letter from the NRC dated April 26, 2001, "Grand Gulf Nuclear Station, Unit 1-Issuance of Amendment RE: Revision of the Minimum Critical Power Ratio Safety Limit for Cycle 12 Operation (TAC No. MB0514)".
2.0 PROPOSED CHANGE
Entergy proposes the following changes to the GGNS TS:
"* TS Limiting Conditions for Operations (LCO) 3.3.7.1 to correct a wording omission introduced in Amendment No. 145 by letter from W. A. Eaton to the USNRC dated January 21, 2000, "GGNS Pilot Full-Scope Application of NUREG-1465 Alternative Source Term Insights, LDC 1999-082,"
"* TS LCO 3.6.5.4 to correct a specified value identified as being non-conservative during instrument uncertainty and setpoint reviews,
"* TS 5.2 subsections 5.2.1 and 5.2.2 to reflect current position specific terminology,
"* TS 5.3.1 to make the requirement consistent with the Quality Assurance Program Manual (QAPM),
"* TS 5.5.8.b to correct an existing typographical error,
"* TS 5.5.11 to reflect changes in terminology used in the new 10 CFR 50.59 Rule,
"* TS 5.6.5.a.5 to clarify references as stipulated in a letter dated April 26, 2001 from the USNRC to Mr. W. A. Eaton " Grand Gulf Nuclear Station, Unit I - Issuance of Amendment RE: Revision of the Minimum Critical Power Ratio Safety Limit for Cycle 12 Operation (TAC No. MB0514)", and
"* TS 5.7 subsections 5.7.1, 5.7.2 and 5.7.3 to reflect current job titles/activities and clarify guard posting requirements.
In summary, the proposed changes to TS 3.3.7.1, 5.2, 5.5.8.b, 5.6.5.a.5, and 5.7 are editorial and maintain compliance with the intent of regulatory requirements. The proposed changes to TS 5.3.1 are intended to provide consistency between the TS and the Quality Assurance Program Manual as approved by the NRC staff. The proposed change to TS 5.5.11 is intended to maintain consistency between the TS and 10 CFR 50.59. The proposed change to TS 3.6.5.4 corrects the bounding value to be consistent with the current FSAR analyses.
to GNRO-2002/00030 Page 2 of 8
3.0 BACKGROUND
TS 3.3.7.1, "Control Room Fresh Air (CFRA) System Instrumentation," was amended as part of the Alternative Source Term Full-Scope application. The proposed change was approved by Amendment No. 145 to the GGNS Operating License (TAC No. MA8065). During this process, the change to Condition B was issued as submitted but was not worded per the Nuclear Energy Institute's writers guide. This error was noted during the implementation phase of this amendment but was determined to not be correctable without formal request from the licensee.
The proposed change corrects this error by adding the words "not met" to Condition B.
TS 3.6.5.4, "Drywell Pressure," establishes limits on the drywell-to-primary containment differential pressure. This parameter is an assumed initial condition in the analyses that determine the primary containment thermal hydraulic and dynamic loads during a postulated Loss of Coolant Accident (LOCA). The limit on negative drywell-to-primary containment differential pressure ensures that changes in calculated peak LOCA drywell pressures due to differences in water level of the suppression pool and the drywell weir annulus are negligible. It also ensures that the possibility of weir wall overflow after an inadvertent upper pool dump is minimized. The limit on positive drywell-to-primary containment differential pressure helps ensure that the horizontal vents are not cleared with normal weir annulus water level. The current value for this parameter was reviewed during a recent instrument uncertainty and setpoint calculation review effort. This review determined that the current value was not bounding in all situations and should be changed. This discrepancy was documented in the plant's Corrective Action Program.
TS 5.2, subsections 5.2.1 and 5.2.2, currently contain job terminology, which is no longer desired for use at the site. The current terminology is also not consistent with that used in the latest revision of ANSI/ANS 3.1 to which the site is committed to. The specific functions related to this'proposed change are in the radiation monitoring and controls area.
TS 5.3.1, "Unit Staff Qualifications," currently commits the site to the 1971 version of ANSI N18.1 for members of the Unit Staff. This version has been superceded by a later version entitled ANSI/ANS-3.1-1978. This later version was endorsed in the new common Quality Assurance Program Manual for all Entergy Sites. This was approved by letter from John N.
Hannon (NRC) to Michael R. Kansler (EOI), "Consolidation of Quality Assurance (QA) Programs into One Quality Assurance Program Manual for all Entergy Sites-Arkansas Nuclear One, Grand Gulf Nuclear Station, River Bend Station and Waterford Steam Electric Station (TAC M97893)",
dated November 6, 1998. The proposed change will not affect any special restrictions contained in TS 5.3.1.
TS 5.5.8.b contains requirements for an Explosive Gas and Storage Tank Radioactivity Monitoring Program. A typographical error was made in this TS during the initial conversion to the Improved Technical Specifications. This was issued as Amendment No. 120 in a NRC letter to Mr. C. Randy Hutchinson dated February 21, 1995, Issuance of Amendment No. 120 to Facility Operating License No. NPF-29 Grand Gulf Nuclear Station, Unit 1 (TAC No. M88101).
TS 5.5.11 Technical Specifications (TS) Bases Control Program contains wording that is no longer consistent with that used in the revised 10 CFR 50.59 Rule. The Federal Register Notice publishing the revised R6le contained guidance that allowed continued use of current programs without any issues. Revised wording was proposed via the Industry/TSTF Standard Technical to GNRO-2002/00030 Page 3 of 8 Specification Change Traveler Process as TSTF-364, which was subsequently approved by the NRC. Entergy is including this change to remain consistent with NUREG 1434, Rev. 2 and 10 CFR 50.59.
TS 5.6.5.a.5 Core Operating Limits Report (COLR) was revised by Amendment No. 146 as issued by letter from the NRC dated April 26, 2001, "Grand Gulf Nuclear Station, Unit I Issuance of Amendment RE: Revision of the Minimum Critical Power Ratio Safety Limit for Cycle 12 Operation (TAC No. MB0514)". In the Safety Evaluation for this amendment, the NRC documented a need for the licensee to revise the TS to clarify certain references contained therein. This change request provides the requested clarification.
TS 5.7, subsections 5.7,1, 5.7.2 and 5.7.3, establish administrative controls for high radiation area entry, posting, and guarding. Sections 5.7.1 and 5.7.2 currently refer to job titles/functions that are no longer desired for use at the station. In the case of section 5.7.3, the current wording has led to some confusion as to when a guard must be posted. The proposed change is intended to clarify the intent by either having a guard posted or meeting the other stipulations of the specification at all times. This will eliminate the need to determine if a guard can be posted and demonstrating this fact to other parties.
4.0 TECHNICAL ANALYSIS
4.1 Technical Specification 3.3.7.1 The format and content of the TS is controlled through the utilization of a standard writer's guide. The guidance currently being utilized is NEI 01-03, Writer's Guide for the lmproded Standard Technical Specifications. The guidance in section 4.1.6.i.5 stipulates that certain Conditions end with the phrase "not met". This phrase was omitted from Condition B of this specification in the amendment to incorporate the Alternative Source Term Full-Scope application. This change is strictly administrative in nature and has no impact on the operation of the plant. The requested change will bring the TS back into compliance with the writer's guide and with the Standard Technical Specification (STS), NUREG 1434 Rev. 2.
4.2 Technical Specification 3.6.5.4 Drywell-to-primary containment differential pressure is a key parameter for ensuring over all containment function under design basis accident conditions. The parameter is controlled through the setpoint for the normal drywell vacuum breaker.
The maximum allowed (analytical) negative drywell-to-primary containment differential pressure is limited to prevent an excessive increased drywell side suppression pool water level due to the differential pressure. A higher water level in the suppression pool on the drywell side has two negative effects. The first is a higher resultant drywell accident pressure, as it will take longer for suppression pool vent clearing during a Loss of Coolant Accident (LOCA). The second is the potential for equipment damage in the drywell if weir wall overflow occurred during an inadvertent upper containment pool dump.
The current Technical Specification (TS) value of -0.26 psid was used in the calculations for weir wall overflow. The evaluation of weir wall overflow is discussed in a letter from L. F. Dale 1'
Attachment I to GNRO-2002/00030 Page 4 of 8 to the U. S. Nuclear Regulatory Commission (USNRC) dated August 19, 1982, AECM 82/353.
The results from these calculations determined that there were no adverse consequences from weir wall overflow at this value.
The analytical value used for the vent clearing analysis was -0.25 psid and not -0.26 psid as discovered during the aforementioned review effort. The vent clearing analysis is described in subsection 6.2.1.1.6 of the Updated Final Safety Analysis Report (FSAR) and was also discussed in a letter from L. F. Dale to the USNRC dated October 22, 1982, AECM-82/497.
Therefore, the current TS value does not bound the value needed to support the vent clearing analysis. This discrepancy was documented in the plant's Corrective Action Program. The bounding limit of -0.25 psid is currently being controlled under administrative controls until such time as the TS is amended.
4.3 Technical Specification 5.2 The proposed changes to sections 5.2.1 and 5.2.2 are administrative in nature. The changes reflect the current terminology and titles for positions performing the related activities at the site.
This proposed change only affects those positions pertaining to radiation protection related work activities. The requirements of TS 5.3 Unit Staff Qualifications will remain applicable to these positions. Therefore, the changes have no effect on the qualifications, functions or organizational freedom of the positions affected.
4.4 Technical Specification 5.3 This proposed change would eliminate the need for maintaining dual qualification/certification records for Grand Gulf Nuclear Station (GGNS) personnel. Currently the TS invoke a different standard than does the Quality Assurance Program Manual (QAPM). This has led to duplicated documentation since the different versions are not exactly the same. This change is considered administrative in nature since the NRC has previously approved the use of ANSI/ANS 3.1-1978 as part of the approval of the current QAPM for Entergy. The technical merits of the two standards were compared and deemed appropriate during the approval process for the QAPM.
Thus, the TS reference to ANSI N18.1, 1971 will be replaced with ANSI/ANS 3.1-1978.
A clarifying statement is also being proposed to allow the use of the QAPM as the single document to control exceptions or clarifications to the standard. This is proposed to minimize the potential for having conflicting upper tier documents. Additionally, this will allow Entergy to only have to change one document if any additional clarifications are needed in the future. The current QAPM already contains some clarifications, which are not currently in the TS.
Special requirements contained in TS 5.3.1 for the radiation protection manager and the STA positions will not be changed by the proposed amendment.
4.5 Technical Specification 5.5.8 b The proposed change to TS 5.5.8.b is an administrative change to correct an obvious typographical error made during the original conversion to the Improved Technical Specifications. The word "or" is being corrected to "for". The proposed change has no bearing on the technical content of the existing specification and is clearly typographical in nature.
to GNRO-2002/00030 Page 5 of 8 4.6 Technical Specification 5.5.11 The NRC amended 10 CFR 50.59 concerning the authority for licensees of production or utilization facilities, to make changes to the facility or procedures, or to conduct tests or experiments, without prior NRC approval. The final rule clarifies the specific types of changes, tests, and experiments 6*onducted at a facility that require evaluation, and revises the criteria licensees must use to determine when NRC approval is needed before such changes, tests, or experiments can be implemented. The final rule also adds definitions for terms that have been subject to differing interpretations, and reorganizes the rule language for clarity. The Bases Control Program required by TS 5.5.11 allows Entergy to make changes to the Bases without NRC approval provided the change does not involve a change to the FSAR or Bases that involves an unreviewed safety question as defined in the old 10 CFR 50.59. With the revision to 10 CFR 50.59, the definition of unreviewed safety question was eliminated. Therefore, the TS should be revised to be consistent with the revision to 10 CFR 50.59. This is considered to be an administrative type change since the NRC has previously approved the change being sought. The change is consistent with the Standard Technical Specification, NUREG 1434, Rev. 2.
4.7 Technical Specification 5.6.5.a.5 The proposed change to TS 5.6.5.a.5 is an administrative change that clarifies a reference contained in TS 5.6.5.a.5. The current reference to LCO 3.3.1.1 does not identify the particular function to which the Core Operating Limits Report (COLR) applies. The proposed change clarifies that the setpoint limits for function 2.d of Table 3.3.1.1-1, the Average Power Range Monitor (APRM) flow biased simulated thermal power - high trip, are to be specified in the COLR. Table 3.3.1.1-1 does not need revision since footnote b already states that the allowable values for this function are specified in the COLR.
The NRC staff identified the desire for this change in the safety evaluation for Amendment No.
146. The evaluation was issued in a letter from the USNRC to William A. Eaton, "Grand Gulf Nuclear Station, Unit 1, Issuance of Amendment RE: Revision of the Minimum Critical Power Ratio Safety Limit for Cycle 12 Operation (TAC No.MB0514)" dated April 26, 2001. In this letter, the staff documented an understanding that Entergy would revise this TS in a reasonable time frame. The safety evaluation stated that this proposed clarification had no direct affect on the determination of the safety limit minimum critical power ratio (SLMCPR).
4.8 Technical Specification 5.7 TS 5.7 contains the administrative controls for high radiation areas. The proposed change involves the title descriptions for personnel performing radiation protection activities. The term "health physics technician" is changed to "health physicists" and "health physics supervision" is changed to "radiation protection supervision". The changes do not change the qualification requirements or the technical capabilities of the assigned individuals currently in the affected positions. These changes are administrative in nature and are intended to reflect the current terminology used in the industry.
Additionally, the phrase "shift superintendent on duty" in section 5.7.2 is revised to "Operations shift management". The current wording causes confusion as to the level of involvement required of the shift superintendent regarding key control. This change clarifies that the control to GNRO-2002/00030 Page 6 of 8 of keys for doors that are locked to prevent unauthorized entry into certain high radiation areas may be delegated to any of the Operations shift management positions. The proposed change does not reduce the effectiveness of controls for prevention of unauthorized entry into the locked high radiation areas.
Additionally, in subsection 5.7.3 there is a discussion concerning use of barricades and postings for areas exceeding 1000 mrem/hr. This subsection requires clarification to remove the ambiguity concerning the posting of guards. The proposed change eliminates the need for determining if a guard can be posted and proposes to either require a guard to be posted or that the area be controlled as required by the technical specification. The proposed change is more simple, straightforward and easier to understand. The requirement that restricts access to areas of high radiation levels will continue to be assured by the proposed change.
5.0 REGULATORY ANALYSIS
5.1 Applicable Regulatory Requirements/Criteria The proposed changes have been evaluated to determine whether applicable regulations and requirements continue to be met. The proposed changes to TS 3.3.7.1, 5.2, 5.5.8.b, 5.6.5.a 5, and 5.7 are editorial and maintain compliance with the intent of regulatory requirements. The proposed changes to TS 5.3.1 are intended to provide consistency between the TS and the Quality Assurance Program Manual as approved by the NRC staff. The proposed change to TS 5.5.11 is intended to maintain consistency between the TS and 10 CFR 50.59. The proposed change to TS 3.6.5 4 corrects the bounding value to be consistent with the current FSAR analyses.
Entergy has determined that the proposed changes do not require any exemptions or relief from regulatory requirements, other than the TS, and do not affect conformance with any GDC differently than described in the FSAR.
5.2 No Significant Hazards Consideration Entergy Operations, Inc. (Entergy) proposes to amend the Grand Gulf Nuclear Station, Unit I (GGNS) Technical Specifications (TS) to correct or clarify certain requirements or information.
The proposed amendment will revise TS 3.3.7.1, "Control Room Fresh Air (CRFA) System Instrumentation"; 5.2, "Organization"; 5.3.1,"Unit Staff Qualification"; 5.5.8.b, "Explosive Gas and Storage Tank Radioactivity Monitoring Program"; 5.6.5.a.5, "Core Operating Limits Report"; and 5.7, "High Radiation Area". Additionally, Entergy is requesting to correct the limiting value specified for TS 3.6.5.4, "Drywell Pressure".
Entergy has evaluated whether or not a significant hazards consideration is involved with the proposed amendment by focusing on the three standards set forth in 10 CFR 50.92, "Issuance of amendment," as discussed below:
- 1. Does the proposed change involve a significant increase in the probability or consequences of an accident previously evaluated?
Response: No.
Attachment I to GNRO-2002/00030 Page 7 of 8 The proposed changes are primarily to correct word omissions, typographical errors, reflect current terminology, and make the TS consistent with other NRC approved documents. These changes are all of an administrative nature and have no effect on any plant equipment or structures. Therefore, these changes do not increase the probability or consequences of an accident previously evaluated.
The proposed amendment also revises the allowed drywell-to-primary containment differential pressure limit. This limit is intended to ensure that containment conditions are consistent with safety analyses. The proposed smaller negative pressure ensures that the design assumptions for the containment will be met if and when a postulated loss of coolant (LOCA) should occur. Moving the limit in a conservative direction will not increase the probability or consequences of previously evaluated accidents.
- 2. Does the proposed change create the possibility of a new or different kind of accident from any accident previously evaluated?
Response: No.
The proposed changes do not involve a physical alteration of the plant. No new or different equipment or modes of operation are being introduced by this proposed change. Thus, the changes do not create the possibility of a new or different kind of accident from any accident previously evaluated.
The change to the allowed drywell-to-primary containment differential pressure limit does not adversely impact the ability of the containment to perform its intended function. The establishment of a more conservative limit for this parameter ensures that the plant stays within current safety analysis and therefore, can not create the possibility of a new or different kind of accident.
- 3. Does the proposed change involve a significant reduction in a margin of safety?
Response: No.
Margin of safety is related to the confidence in the ability of the fissioh product barriers to perform their design functions during and following an accident situation. These barriers include the fuel cladding, the reactor coolant system, and the containment system. The proposed changes are primarily administrative in nature and can not affect any safety barriers. The proposed change to the allowed drywell-to-primary containment differential pressure limit establishes a more conservative limit for a key parameter for the containment than is currently specified in the TS. The revised differential pressure limit is consistent with'current assumptions of the accident analysis. Therefore, the proposed change does not involve a significant reduction in a margin of safety.
Based on the above, Entergy concludes that the proposed amendment(s) present no significant hazards consideration under the standards set forth in 10 CFR 50.92(c), and, accordingly, a finding of "no significant hazards consideration" is justified.
Attachment I to GNRO-2002/00030 Page 8 of 8 5.3 Environmental Considerations The proposed amendment does not involve (i) a significant hazards consideration, (ii) a significant change in the types or significant increase in the amounts of any effluent that may be released offsite, or (iii) a significant increase in individual or cumulative occupational radiation exposure. Accordingly, the proposed amendment meets the eligibility criterion for categorical exclusion set forth in .,JO CFR 51.22(c)(9). Therefore, pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental assessment need be prepared in connection with the proposed amendment.

Attachment 3 GNRO-2002100030 Changes to Technical Specification Bases Pages (For Information Only) to GNRO-2002/00030 Page 1 of 3 Drywell Pressure B 3.6.5.4 B 3.6 CONTAINMENT SYSTEMS B 3.6.5.4 Orywell Pressure BASES BACKGROUND Drywell-to-primary containment differential pressure is an assumed initial condition In the analyses that determine the primary containment thermal hydraulic and dynamic loads during a postulated loss of coolant accident (LOCA).
If drywell pressure is less than the primary containment airspace pressure, the water level in the weir annulus will increase and, consequently, the liquid inertia above the top vent will increase. This will cause top vent clearing during a postulated LOCA to be delayed, and that would increase the peak drywell pressure. In addition, an inadvertent upper pool dump occurring with a negative drywell-to-primary containment differential pressure could result in overflow over the weir wall.
The limitation on negative drywell-to-primary containment differential pressure ensures that changes in calculated peak LOCA drywell pressures due to differences in water level of the suppression pool and the drywell weir annulus are negligible. It also ensures that the possibility of weir wall overflow after an inadvertent upper pool dump is minimized. The limitation on positive drywell-to-primary containment differential pressure helps ensure that the horizontal vents are not cleared with normal weir annulus water level.
APPLICABLE Primary containment performance is evaluated for the entire SAFETY ANALYSES spectrum of break sizes for postulated LOCAs. Among the inputs to the design basis analysis is-the initial drywell internal pressure (Ref. 1). The initial drywell internal pressure affects the drywell pressure response to a LOCA (Ref. 1) and the suppression pool swell load definition (Ref. 2).
Additional analyses (Refs. 3 and 4) have been performed to show that if initial drywell pressure does not exceed the negative pressure limit, the suppression pool swell and vent clearing loads will not be significantly increased and the probability of weir wall overflow is minimized after an inadvertent upper pool dump.

GRAND GULF B 3.6-120 Revision No. 0 to GNRO-2002/00030 Page 2 of 3 Drywell Pressure B 3.6.5.4 BASES APPLICABLE Drywell pressure satisfies Criterion 2 of the NRC Policy SAFETY ANALYSES Statement.
(continued)
LCO A limitation on the drywell-to- mary containment differential pressure of ; -0.2ipsid and s 2.0 psid is required to ensure that suppression pool water is not forced over the weir wall, vent clearing does not occur during normal operation, containment conditions are consistent with the safety analyses, and LOCA drywell pressures and pool swell loads are within design values.
APPLICABILITY In MODES 1, 2, and 3, a DBA could cause a release of radioactive material to the primary containment. In MODES 4 and 5, the probability and consequences of these events are reduced due to the pressure and temperature limitations of these MODES. Therefore, maintaining the drywell-to-primary containment differential pressure limitation is not required in MODE 4 or 5.
ACTIONS A.1 With drywell-to-primary containment differential pressure not within the limits of the LCO,- it must be restored within I hour. The Required Action is necessary to return operation to within the bounds of the safety analyses. Thd I hour Completion Time is consistent with the ACTIONS of LCO 3.6.5.1, *Drywell,* which requires that the drywell be restored to OPERABLE status within I hour.
B.1 and B.2 If drywell-to-primary containment differential pressure cannot be restored to within limits within the required Completion Time, the plant must be brought to a MODE in which the LCO does not apply. To achieve this status, the plant must be brought to at least MODE 3 within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> and to MODE 4 within 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br />. The allowed Completion Times are reasonable, based on operating experience, to reach the required plant conditions from full power conditions in an orderly manner and without challenging plant systems.
