- 1. Entergy letter dated June 30, 2003, License Amendment Request Revision of Section 6.0, Administrative Controls (2CAN060303)
Dear Sir or Madam:
By letter (Reference 1), Entergy Operations, Inc. (Entergy) proposed a change to the Arkansas Nuclear One, Unit 2 (ANO-2) Technical Specifications (TSs) to: 1) reorganize Section 6.0, Administrative Controls; 2) modify the actions and surveillance requirements (SRs) of various other TSs to support the reorganization; 3) modify several action and SRs that are related to systems that are shared by ANO-2 and ANO, Unit 1 (ANO-1);
and 4) change various TS bases as needed to support the above changes.
On September 26, 2003, Entergy received 12 questions which were determined to need formal response. Entergy's response is contained in Attachment 1.
In addition, Entergy is proposing two changes that were not included in the previous submittal (Reference 1). One change will increase the minimum fuel volume specified in TS 3.8.1.1.b and 3.8.1.2.b for the emergency diesel generator day tank. The other change corrects a typographical error. These changes are described in Attachment 1.
Two TS amendments (249 and 251), which have been approved since Entergy submitted the original proposed changes in Reference 1, affect pages that were submitted with Reference 1. New marked up and clean pages are included in Attachments 2 and 3 based on the approval of these two amendments.
The original no significant hazards consideration (NSHC) included in Reference 1 is affected by information contained in this supplemental letter. One additional less restrictive change has been identified and is included in the updated NSHC. One change that was classified as less restrictive is being reclassified as a more restrictive change.
Letter #
Page 2 of 2 The list of commitments included in the previous submittal (Reference 1) is being revised. One of the commitments stated in part that the details of the Ventilation Filter Testing Program (VFTP) will be relocated to the TRM. The details of the VFTP will be maintained in site procedures. Another commitment is changed to include the relocation of details related to the change proposed to the facility operating license condition 2.c.(6). A complete list of the commitments, as modified, is included as Attachment 4.
If you have any questions or require additional information, please contact Dana Millar at 601-368-5445.
I declare under penalty of perjury that the foregoing is true and correct. Executed on .

Response to Request for Additional Information
Attachment I to Letter #
Page 1 of 22 Response to Request for Additional Information Related to the Revision of Section 6.0, Administrative Controls Question 1:
The current wording in 2CTS Table 3.3-1 Action 2 and 2CTS Table 3.3-3 Action 10 states in part "shall be reviewed at the next regulady scheduled PSC meeting in accordance with the QA Manual Operations." The wording in PTS Table 3.3-1 Action 2 and PTS Table 3.3-3 Action 10 is changed to "shall be reviewed as soon as possible but no later than the next regulary scheduled OSRC meeting in accordance with the Quality Assurance Program Manual (QAPM)."As currently written the 2CTS statement would require that a review of the desirability of maintaining a channel in the bypassed condition for greater than 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> is required at the next scheduled" PSC meeting and could not be performed at a "called" meeting held before the next "schedule" meeting. If this review were performed prior to the next "scheduled" meeting, the intent would still be satisfied. While the staff finds the change acceptable, it does not believe the change is an administrative change. The change is a less restrictive (L) change, since it would allow any PSCIOSRC meeting prior to the next scheduled meeting to review the desirability of maintaining the change in the bypass condition. Comment: Provide a discussion andjustification for this less restrictive (L) change.-
Response 1:
The proposed change will be considered less restrictive and classified as L16. The current requirement to review the desirability of maintaining a channel in a bypassed condition at the next scheduled On Site Safety Review Committee (OSRC) meeting is excessive, as it does not provide the flexibility to perform the review sooner than the next regularly scheduled meeting. The proposed change allows the option to review the desirability of maintaining a channel in a bypassed condition prior to or at the next scheduled OSRC meeting. The review is adequately performed regardless of the timing of the meeting, New marked up pages are included. No changes are proposed to the clean pages, which were submitted to the NRC by Entergy letter dated June 30, 2003.
Question 2:
2CTS Table 4.3-3 Item 2.b is modified by Note 6. The note provides a three (3)hour time period with the monitor inoperable to conduct the CHANNEL FUNCTIONAL TEST without entering the associated Actions. DOC L.2 states that the note was first included NUREG-1432, revision 0 by the lead plant that converted to ITS. This statement is in error NUREG-1432 does not allow this relaxation. The current reference is NUREG-1432, Rev 0.
Comment: Correct this discrepancy.
Response 2:
Discussion of Change (DOC) L2 is corrected below:
L2 Note 6 will be added to current Technical Specification (CTS) Table 4.3-3. The note provides a three (3) hour time period with the monitor inoperable to conduct the CHANNEL FUNCTIONAL TEST without entering the associated Actions. This note to Letter #
Page 2 of 22 was first included in NUREG-1430, revision 0 by the lead plant that converted to the improved Technical Specification (ITS). The time allowance was based on the historical average time frame for conducting the test and the need to conduct the test during conditions for which the monitor is normally required to be OPERABLE. The note was approved for inclusion in the Arkansas Nuclear One, Unit 1 (ANO-1) ITS conversion and as such provides precedence for this request. When performing the channel functional test on the radiation monitors, the monitors' intended function of isolating the control room and starting the appropriate emergency ventilation system is demonstrated. Therefore, it is necessary that while performing the test the control room not be in the emergency ventilation mode as might be required by actions associated with inoperable monitors.
Question 3:
In converting 2CTS 4.7.6.1.2.d.2 to PTS 4.7.6.1.2.b the words either actual or simulated" were added to allow actuation signals to be used to satisfy the surveillance requirement.
This was justified by Doc L. 11. This change is acceptable; however, the change was incomplete. 2CTS 4.7.6.1.2.d.2 specifies that the "control room high radiation test signal" is to be used. These words were not changed in converting to PTS 4.7.6.i1.2.b. Thus the word "test" would still restrict the surveillance to a simulated signal. The word "test" should be deleted so that it will be consistent with ANO-1 SR 3.7.9.3. Comment: Correct this discrepancy.
Response 3:
The word test' will be removed. Surveillance Requirement (SR) 4.7.6.1.2.b will be worded:
" At least once per 18 months by verifying that on a control room high radiation signal, either actual or simulated, the system automatically isolates the control room and switches into a recirculation mode of operation." A minor change is proposed to DOC LI1I, which was included in Entergy's letter to the NRC dated June 30, 2003, License Amendment Request Revision of Section 6.0, Administrative Controls (2CAN060303). New marked up and clean pages are included in Attachments 2 and 3 respectively.
L1 SR 4.7.6.1.2.d.2 will be relocated to SR 4.7.6.1.2.b and an option to verify the system automatically isolates by using either an actual or a simulated signal. This allows satisfactory automatic system initiations for other than surveillance purposed to be used to fulfill the surveillance requirements. OPERABILITY is adequately demonstrated in either case since the system cannot discriminate between "actual" or "simulated' signals.
Question 4:
As stated in RAI 3/4 7-3 a mistake was made in converting ICTS 4.10. l.a and 4.10.2.a to ITS SR 3.7.9.1 and SR 3.7.10.1 in that the phrase "STAGGERED TEST BASES" was relocated to the ITS Bases byANO-1 DOC LA. 1. It was also stated in RAI 3/4.7-3 that the format and structure of the ITS/STS and 10CFR50.36(s) do not allow the Bases to dictate licensing requirements, particularly frequency requirements. Thus the frequency to perform ITS SR 3.7.9.1 and SR 3.7.10.1 is 31 days with no legal requirement to stagger the tests. In
Attachment I to Letter #
Page 4 of 22 oil system not within limits. PTS 3.8.1.3 Actions 2 and 3 specify that remedial measures to be taken when the diesel fuel oil properties specified in the program (PTS 6.5.13) are not within limits. However, there is no corresponding surveillance requirement for these Action statements similar to ITS SR 3.8.3.2. Comment: Revise the CTS/PTS markup of 2CTS 4.8.1.1.2 and PTS 3/4 8.1.3 to include a SR similar to ITS SR 3.8.3.2 and provide the appropriate justification and discussion for this administrative change.
Response 5:
A new SR will be added as SR 4.8.3.1.2. The SR will state: uVerify fuel oil properties of new and stored fuel oil are tested in accordance with, and maintained within the limits of the Diesel Fuel Oil Testing Program.' The frequency of performance will be in accordance with the Diesel Fuel Oil Testing Program, which is PTS 6.5.13. The proposed change is administrative and will be classified as A36. The proposed SR provides a link to assure the proposed diesel fuel oil testing program is implemented. PTS SR 4.8.3.1 will be renumbered as SR 4.8.3.1.1 to accommodate the new SR.
Question 6:
DOC M.8 describes andjustifies the changes made in converting 2CTS 6.8. 1.d to PTS 6.4. 1.d. DOC M.8 states the following: Witten procedures for the ODCM will be required by PTS 6.4.d." The PTS does not contain a specification 6.4.d. Comment: Correct this discrepancy.
Response 6:
The section that should have been referenced is PTS 6.4.1.d. DOC M8 is corrected as follows:
M8 PTS 6.4.1.d - Requirements will be included to provide procedures for each of the programs identified in PTS 6.5. The proposed change is consistent with the NUREGs and is an additional restriction on unit operation. CTS 6.8.1.i, ODCM and PCP implementation will be relocated to the Programs section. Written procedures for the ODCM will be required by PTS 6.4.1.d. Therefore, the ODCM and PCP do not need to be listed separately in section 6.4.
Question 7:
A number of changes were made in converting 2CTS 6.8.4.a.5 to PTS 6.5.4.e. The justification used for these changes DOC A.35 states that they are acceptable because they are consistent with TSTF-308. As stated in RAI 1.0-1 "Consistency with the ITS or STS is not an adequate justification for concluding a change is acceptable....This also implies to any changes made as a result of TSTF's (i.e., TSTF-287)." Comment: Revise the discussion andjustirication for this administrative change in light of the above discussion and RAI 1.0-1.
Attachment 1to Letter #
Page 5 of 22 Response 7:
The proposed change is an administrative change that provides clarity to the intended requirements for determining cumulative and projected dose contributions. Cumulative dose contributions are determined for the current calendar quarter and the current calendar year.
However, the projected doses are not determined for an entire calendar quarter or calendar year. Therefore, the change provides clarity. In addition, the CTS wording states that the dose contributions will be determined using the methodology and parameters in the ODCM.
The proposed change eliminates the word parameters" from the sentence related to projected dose. There is no practical difference between methodology and parameters" and methodology." The change will continue to be classified as A35 with the addition of the above justification.
Question 8:
RAI 6.0-30 requested additionaljustification and discussion on the relocation of that portion of 2CTS 6.9.1.5.c related to the reporting requirements for the LTOP safety valve challenges. DOC LA.3 restated that this commitment was part ofAmendment 180 dated March 7, 1997, and that this commitment is being deleted using the allowances of the Commitment Management Program. The allowances contained in the Commitment Management Program are an unacceptable justification from removal of a TS commitment.
Comment: Provide a justification and discussion on the deletion of the reporting requirement for LTOP safety valve challenges.
Response 8:
Entergy is not removing an operating license change by the proposed revision, but to only make the change consistent with the current NUREG 1432 guidance. When the commitment to report LTOP relief valve actuations was made as reported in the safety evaluation for Amendment 180 to the ANO-2 Operating License, no actual change to the ANO-2 TSs was made. Therefore, the commitment deletion performed by Entergy for the LTOP reporting commitment did not change the TSs.
SECY-95-300 endorsed the Nuclear Energy Institute's Guidance Document, Guideline for Managing NRC Commitments." The NEI Guidance document was updated in July 1999 as NEI 99-04, Guidelines for Managing NRC Commitment Changes.' The guidance document, which is reflected in Entergy's Commitment Management Program, allows the deletion of commitments that were specific statements in NRC safety evaluation reports which credited specific licensee commitments as being the basis for an NRC staff safety conclusion. The process states that if the commitment has been implemented, that the licensee can notify the NRC in a summary report. Changes to commitments are summarized to the NRC in ANO's Annual Operating Report.
The reporting of challenges to pressurizer safety valves per TS 6.9.1 .5.c is not directly related to the commitment for reporting of LTOP actuations. However, at the time that the commitment was being made NUREG 1432 included the report for challenges to pressurizer safety valves. The commitment to report challenges to the LTOPs was related to this reporting requirement only to define the basis / schedule for the report. In 1997, the NRC issued Generic Letter (GL) 97-02, Revised Contents of the Monthly Operating Report." The to Letter#
Page 6 of 22 GL did not specifically identify the need to report challenges to the pressurizer safety and relief valves. The bases for deleting the commitment to report challenges to the LTOP safety valves is consistent with the absence of need to report challenges to the pressurizer safety and relief valves.
Question 9:
2CTS 6.9.5.1.13 through 6.9.5.1.16 reference the NRC approval letters for the methodologies specified in 2CTS 6.9.5.1.4, 6.9.5.1.5, 6.9.5.1.6, 6.9.5.1.8, 6.9.5.1.9, and 6.9.5.1.11. In converting the CTS to the PTS the above methodology references were changed to 6.6.5.4, 6.6.5.5, 6.6.5.6, 6.6.5.8, 6.6.5.9, and 6.6.5.11, respectively. These reference specifications are in error; the correct specifications are 6.6.5.b.4, 6.6.5.b.5, 6.6.5.b.8, 6.6.5.b.9, and 66.5.b.11, respectively. Comment: Correct this error.
Response 9:
See corrected pages in Attachments 2 and 3.
Question 10:
In converting FOL 2.C. (5) to PTS 6.5.2 the phrase at a frequency not to exceed refueling cycle intervals" is changed to at least once per 18 months.' This change is justified by DOC L.14. Based on the justification provided in DOC L.14, refueling cycle intervals are defined as 18 months which is consistent with current requirements, thus the change should be considered as an administrative change. However, this change is based on the same change made by TSTF-299. TSTF-299 justifies and classifies this change as a More restrictive change. The reason for this is that even through a refueling cycle interval maybe defined at ANO-2 as 18-months, when one factors in the startups, shutdowns, and down time for maintenance and repairs during this interval, the time may exceed 18 months plus the 25% allowance allowed by 2CTS 4.0.2. Thus restricting the time interval to at least once per 18 months" is a More restrictive change. Comment: Revise the CTS markup and provide ajustification and discussion for this More restrictive change.
Response 10:
The CTS markup will be revised to classify this as a more restrictive change and designate it as M15. The proposed change results in consistency with the surveillance test frequency notation that is included in other ANO-2 Technical Specification Surveillance Requirements.
A new marked up page is included in Attachment 3.
Question 11:
DOC L. Ijustifies the change made in converting 2CTS 4.8.1.1.2.b to PTS 6.5.13.c. The last sentence for DOC L. I states the following: The periodic testing..stored DG fuel oil will support SG operability." The DG fuel oil does not support steam generator (SG) operability, but it does support diesel generator (DG) operability. Comment: Correct this discrepancy.
Response 11:
to Letter#
Page 7of22 Doc LI is corrected as follows:
LI PTS 6.5.13.c will require the periodic testing of stored fuel for particulates only. Refer to MI for added testing requirements. This change reflects industry standard acceptable diesel generator (DG) fuel oil testing programs reflected in NUREG-1432.
Over the storage life of ANO-2 fuel oil, the properties tested by ASTM-D975 are not expected to change and performing these tests once on the new fuel oil (see Ml) provides adequate assurance of the proper quality fuel oil. The periodic testing for particulates monitors a parameter that reflects degradation of fuel oil and can be trended to provide increased confidence that the stored DG fuel oil and can be trended to provide increased confidence that the stored DG fuel oil will support DG operability.
Question 12:
In converting FOL 2.c.(6) to PTS 6.5.2 the markup shows that the phrase in vital areas"is relocatedby DOC LA.2. DOC LA.2 lists specific CTS requirements that are being relocated to license controlled documents and the specific documents to which they are being relocated. No such entry is provided in DOC LA.2 for the relocationassociatedwith FOL 2.c.(6). Comment: Revise DOC LA.2 to include this information.
Response 12:
LA2 This information will be moved to a license controlled document such as the Bases, Safety Analysis Report (SAR), QAPM, Technical Requirements Manual (TRM), etc.
The information provides details of design or process which are not directly pertinent to the actual requirement, i.e., Definition, Limiting Condition for Operation, or Surveillance Requirement, but rather describe additional unnecessary details such as an acceptable method of compliance. Since these details are not necessary to adequately describe the actual regulatory requirement, they can be moved to a licensee controlled document without a significant impact on safety. Placing these details in controlled documents provides adequate assurance that they will be maintained. The Bases will be controlled by the Bases Control Process in Chapter 6 of the PTS.

Page 8 of 22 Additional Changes 1.0 The following change to CTS 3.8.1.1.b.1 and 3.8.1.2.b.1, which was not included in the original requested change, is being proposed. New marked up and clean pages are included.
Discussion of Changes In addition to the previously proposed changes to the limiting condition for operation (LCO) of these two TSs, a change is proposed to the minimum fuel volume in the diesel generator day tanks. The proposed change will increase the minimum contained volume in the day tank from 280 gallons to 300 gallons.
Administrative Changes None Technical Changes - More Restrictive M16 Using a conservative fuel consumption rate, the minimum usable required capacity of each day tank is 263.4 gallons. Each day tank has an unusable volume of 29.4 gallons. Therefore, to assure at least 60 minutes of diesel operation at 110% rated capacity, the minimum contained volume in each day tank should be 292.8 gallons (263.4 + 29.4). The proposed change will conservatively require a minimum volume of 300 gallons in each day tank.
Technical Changes - Less Restrictive None Technical Changes - Removal of Details None Discussion of Differences The diesel day tanks are specific to ANO-2 and are not shared with ANO-1 and therefore no comparison is made to the ANO-1 TS or to NUREG-1432.
2.0 An administrative change is proposed to TS 3.8.1.1, Action c.4. The change is a correction of a typographical error introduced in TS Amendment 249. The action in part states: "Restore the remaining inoperable A.C. Source to an OPERABLE status (Offsite A.C. Circuit within 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> or Diesel Generator with 14 days...' The proposed change will change the portion of the action from "with 14 days" to Within 14 days." The change is classified as Al, administrative. Revised marked up and clean pages are included in Attachments 2 and 3, respectively.
Al The designated change represents a non-technical, non-intent change. Examples of this type of change include: wording preference; convention adoption; editorial, numbering and formatting changes; and hierarchy structure.

Page 3 of 22 converting 2CTS 4.7.6.1.1.a and 4.7.6.1.2.a to PTS 4.7.6.1. 1.a and 4.7.6.1.2.a, the phase "STAGGERED TEST BASES"was not relocated to the Bases, but retained in the PTS; thus the PTS requires that the SRs be perforned on a STAGGERED TESTBASES. This inconsistency between the two specification (ITS and PTS) could cause confusion and misinterpretation on the performance of the SRs and Actions to be taken due to missed surveillances, frequency extensions, and system inoperabilities. Comment: Correct this discrepancy.
Response 4:
The ITS definition of "STAGGERED TEST BASIS" is:
"ASTAGGERED TEST BASIS shall consist of the testing of one of the systems, subsystems, channels or other designated components during the interval specified by the Surveillance Frequency, so that all systems, subsystems, channels or other designated components are tested during n Surveillance Frequency intervals, where n is the total number of systems, subsystems, channels, or other designated components in the associated function."
The ANO-2 CTS definition, which was not proposed for change, states:
"A STAGGERED BASIS shall consist of:
- a. A test schedule for n systems, subsystems, trains or other designated components obtained by dividing the specified test interval into n equal subintervals,
- b. The testing of one system, subsystem, train or other designated component at the beginning of each subinterval."
There are two control room air conditioning units (2VUC-27A and 2VUC-27B) which are tested to meet PTS SR 4.7.6.1.1.a and two control room emergency air filtration systems (VSF-9 and 2VSF-9) which are tested to meet PTS SR 4.7.6.1.2.a. The surveillance frequency is 31 days. The ANO-1 SR, as converted, requires each control room ventilation system (2VUC-27A, 2VUC-27B, VSF-9 and 2VSF-9) to be tested every 31 days. Based on the ANO-2 CTS definition of STAGGERED TEST BASIS, both 2VUC-27A and 2VUC-27B will be tested within the 31 day surveillance interval and both VSF-9 and 2VSF-9 will be tested within the 31 day surveillance interval.
Because the definition of STAGGERED TEST BASIS differs between ITS and the ANO-2 CTS, it is appropriate to leave STAGGERED TEST BASIS in the ANO-2 PTS, which is consistent with the testing requirements reflected in the ANO-1 TS. In both the ANO-1 SRs and the proposed ANO-2 SRs, all fans are tested every 31 days.
Question 5:
In converting 2CTS 4.8.1.1.2.a.2 and 4.8.1.1.2.b to the PTS, two new specifications were added: PTS 6.5.13 describes the diesel fuel oil testing program and its requirements, and PTS 3/4 8.1.3 provides the Limiting Conditions for Operation and Actions for the diesel fuel

Page 9 of 22 3.0 TS Amendments 249 and 251, which were approved after the original submittal, affect two TSs and several pages of the original submittal. New marked up and clean pages are included in Attachments 2 and 3, respectively.
Revised No Significant Hazards Consideration (Note: The previous item identified as number 13 in the list of less restrictive changes has been deleted and the remaining list renumbered; a new item, identified as number 14, is included. A minor change is being made to item number 3.)
Entergy Operations, Inc. proposes to change the Arkansas Nuclear One, Unit 2 (ANO-2)
Technical Specifications (TSs) to reformat, reword, and relocate several specifications and surveillance requirements (SRs) from their current location in the TSs to another location in the TSs. The changes have been classified as administrative (A); less restrictive, administrative deletion of requirements (LA); more restrictive (M); and less restrictive (L).
Administrative Changes:
Rewording and reformatting various TSs will make the TSs more readily understandable to plant operators and other users. Relocation of the specifications will assist in consistency between ANO-2 and ANO, Unit 1 (ANO-1). During the reformatting and rewording process, no technical changes (either actual or interpretational) to the Technical Specifications were made unless they were identified and justified.
Less Restrictive - Administrative Deletion of Requirements Portions of some specifications provide information that is descriptive in nature regarding the equipment, system(s), actions or surveillances. This information is proposed to be deleted from the specifications and relocated to other license basis documents or procedures which are under licensee control. The license bases documents may include the TS Bases, Safety Analysis Report (SAR), Technical Requirements Manual, and Program and Manuals identified in TS Section 6.0, Administrative Controls.' The removal of descriptive information is permissible, because the documents containing the relocated information will be controlled through the applicable process provided by the regulatory requirements, e.g., 10 CFR 50.59, 10 CFR 50.54(a)(3), and TS Section 6.0, Administrative Controls.' This will not impact the actual requirements but may provide some flexibility in how the requirement is conducted. Therefore, the descriptive information that has been moved continues to be maintained in an appropriately controlled manner.
More Restrictive Changes The ANO-2 TSs are proposed to be modified in some areas to impose more stringent requirements than previously required. These more restrictive modifications are being imposed to be consistent with the currently improved ANO-1 TSs and the Standard Technical Specifications Combustion Engineering Plants (NUREG-1432).
Less Restrictive Changes Less restrictive changes that are proposed include the following: (L# in parenthesis is the related explanation in the proposed submittal.)

Entergy Operations, Inc. has evaluated whether or not a significant hazards consideration is involved with the proposed amendment(s) by focusing on the three standards set forth in 10 CFR 50.92, "Issuance of amendment," as discussed below.
- 1. Do the proposed changes nvolve a significant increase in the probability or consequences of an accident previously evaluated?
Response: No.
Administrative Changes:
The proposed changes involve reformatting and rewording of the existing TSs. The reformatting and rewording process involves no technical changes to existing requirements. As such, the proposed changes are administrative in nature and do not impact initiators of analyzed events or assumed mitigation of accident or transient events.
Less Restrictive - Administrative Deletion of Requirements The proposed changes relocate requirements from the TSs to other license basis documents which are under licensee control. The documents containing the relocated requirements will be maintained using the provisions of applicable regulatory requirements.
More Restrictive Changes The proposed changes provide more stringent requirements for the ANO-2 TSs. These more stringent requirements are not assumed to be initiators of analyzed events and will not alter assumptions relative to mitigation of accident or transient events. The more stringent requirements are imposed to ensure process variables, structures, systems, and components are maintained consistent with the safety analyses and licensing basis and to provide greater consistency with the ANO-1 TS and NUREG 1432.
Less Restrictive Changes
- 1) A note will be added that allows three (3) hours to perform the channel functional test on the control room radiation monitors without entering the associated Actions.
The control room area radiation monitor is used to support mitigation of the consequences of an accident; however, it is not considered the initiator of any to Letter #
Page 12 of 22 previously analyzed accident. Also, the addition of the Note to allow time for testing reduces the potential for initiation of a previously analyzed accident due to reduced potential for shutdowns and startups due to incomplete or missed surveillances. As such, the proposed revision to include an allowance for testing does not significantly increase the probability of any accident previously evaluated. This change does not result in any hardware changes, but does allow operation for a limited time with an inoperable monitor for the purposes of testing. Since the capability of the control room area radiation monitor to provide the required information continues to be verified, and the time allowed for inoperability for testing is short, the change will not reduce the capability of required equipment to mitigate the event. Also, the consequences of an event occurring during the proposed operation of the unit during the allowed inoperability for testing are the same as the consequences of an event occurring while operating under the current TS Actions. Therefore, this change does not involve a significant increase in the consequences of any accident previously evaluated.
- 2) This change will allow the control room boundary to be opened intermittently under administrative controls, and will allow both trains of the CREVS to be inoperable due to control room boundary inoperability for a period of 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.
Neither CREVS nor the control room boundary is the initiator of any accident analyzed in the SAR. Therefore, this change does not result in a significant increase in the probability of an accident previously evaluated.
The CREVS and the control room boundary are intended to provide a habitable environment for the control room operators in the event of an accident that results in the release of radioactivity to the environment. The allowance to open the control room boundary intermittently is acceptable, because of the administrative controls that will be implemented to ensure that the opening can be rapidly closed when the need for control room isolation is indicated, restoring the control room habitability envelope.
Allowing both CREVS trains to be inoperable for 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> due to an inoperable control room boundary is acceptable because of the low probability of an accident requiring control room isolation during any given 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> period, because entry into this condition is expected to be an infrequent occurrence, and because preplanned compensatory measures to protect the control room operators from potential hazards are implemented. Therefore, this change will not result in a significant increase in the probability of an accident previously evaluated.
- 3) An allowance will be added to allow use of a simulated" or "actual" signal when testing the automatic isolation feature of the control room air filtration system.
The phrase "actual or simulated" in reference to the automatic initiation signal, has been added to the system functional test surveillance test description. This does not impose a requirement to create an "actual" signal, nor does it eliminate any restriction on producing an "actual" signal. The proposed change does not affect the procedures governing plant operations and the acceptability of creating these signals; it simply would allow such a signal to be utilized in evaluating the acceptance criteria for the system functional test requirements. Therefore, the change does not involve a significant increase in the probability of an accident to Letter#
Page 13 of 22 previously evaluated. Since the function of the system functional test remains unaffected the change does not involve a significant increase in the consequences of an accident previously evaluated.
- 4) An allowance for the diesel fuel storage tanks to contain less than 22,500 gallons of fuel for up to 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> as long as the individual volume is greater than 17,446 gallons will be added. The lower value when summed with the contents of the other tank ensures six days of fuel oil is available. During the 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br />, the diesel generator is capable of performing its intended function. There is a low probability that an event would occur for which the diesel generator would be required during this short period of time when the lower fuel oil volume is allowed.
The AC Sources are used to support mitigation of the consequences of an accident and can be involved in the initiation of the accident analyzed in SAR. Equipment powered by the AC Sources, which may be considered as an initiator, continues to be assured of electrical power. The proposed increased restoration time involves parameters unrelated to initiating the failure of the AC Sources. As such the proposed time allowance for restoration of limited levels of readiness parameter degradation will not increase the probability of any accident previously evaluated.
The proposed changes allow additional time for restoration of parameters that have been identified as not immediately affecting the capability of the power source to provide its required safety function. The identified parameters are capable of being replenished during operation of the diesel generators, and the short additional allowable action time continues to provide adequate assurance of operable required equipment. Therefore, this change does not involve a significant increase in the probability of or the consequences of any accident previously evaluated.
- 5) Seven days will be allowed to restore the stored diesel fuel oil total particulates to within the required limits prior to declaring the associated diesel inoperable.
The testing of diesel generator fuel oil is not considered an initiator, or a mitigating factor, in any previously evaluated accident. .The presence of particulates does not mean failure of the fuel oil to bum properly in the diesel engine. In addition, particulate concentration is unlikely to change significantly between surveillance intervals (31 days). Therefore, the change does not involve a significant increase in the probability or consequences of an accident previously evaluated.
- 6) An allowance for the person who is satisfying the requirement of the radiation protection staff position and for the person filling the Shift Technical Advisor (STA) position to be vacant for not more than two hours in order to provide for unexpected absences is being added. This is consistent with the allowance permitted for the control room operator as reflected in existing TSs.
This change does not result in any changes in hardware or methods of operation. The change allowing the absence of the STA or the radiation protection technician is not considered in the safety analysis, and cannot initiate or affect the mitigation of an accident in any way. Therefore, this change does not involve a significant increase in the probability or consequences of an accident previously evaluated.

- 7) The STA will be allowed to support the shift crew rather than only the shift supervisor. This provides more flexibility and does not dilute the function of the STA.
This change does not result in any changes in hardware or methods of operation. The change in the support relationship between the STA and the control room staff is not considered in the safety analysis, and cannot initiate or affect the mitigation of an accident in any way. Therefore, this change does not involve a significant increase in the probability or consequences of an accident previously evaluated.
- 8) The Occupational Radiation Exposure Report will be submitted by April 30 of each calendar year instead of prior to March 1.
This change does not result in any changes in hardware or methods of operation. The change in date for submittal of "after the fact" information is not considered in the safety analysis, and cannot initiate or affect the mitigation of an accident in any way.
Therefore, this change does not involve a significant increase in the probability or consequences of an accident previously evaluated.
- 9) An allowance is proposed that will revise the high radiation areas to include additional previously approved methods for implementation of alternatives to the "control device" or "alarm signal' requirements of 10 CFR 20. These alternatives provide adequate control of personnel in high radiation areas as evidenced by NRC issuance of NUREG-1432.
The controls for access to a high radiation area are not considered as initiators, or as a mitigation factor, in any previously evaluated accident. Therefore, the change does not involve a significant increase in the probability or consequences of an accident previously evaluated.
- 10) An allowance to require periodic testing of stored fuel for the particulates only is proposed.
The testing of diesel generator fuel oil is not considered an initiator or a mitigating factor in any previously evaluated accident Therefore, the change does not involve a significant increase in the probability or consequences of an accident previously evaluated.
- 11) The removal of the requirement to notify the Vice President, Operations ANO within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> of violating a safety limit.
Notification of the Vice President, Operations ANO when a safety limit is violated is not considered an initiator or a mitigating factor in any previously evaluated accident.
Therefore, the change does not involve a significant increase in the probability or consequences of an accident previously evaluated.
- 12) The Radioactive Effluent Release Report will be submitted by May 1 of each calendar year instead of prior to March 1.

- 13) A change that allows a 25% extension of the frequency in accordance with SR 4.0.2 for the integrated leak tests of each system outside containment that could contain highly radioactive fluids.
The extension of the testing frequency, up to 25% of the test interval, is not considered an initiator or a mitigating factor in any previously evaluated accident.
Therefore, the change does not involve a significant increase in the probability or consequences of an accident previously evaluated.
- 14) A change that allows the OSRC review of the desirability of maintaining a channel in the bypassed condition to be at or before the next regularly scheduled meeting.
The proposed change is not considered an initiator or a mitigating factor in any previously evaluated accident. Therefore, the change does not involve a significant increase in the probability or consequences of any accident previously evaluated.
Therefore, the proposed changes do not involve a significant increase in the probability or consequences of an accident previously evaluated.
- 2. Do the proposed changes create the possibility of a new or different kind of accident from any accident previously evaluated?
Response: No.
Administrative Changes:
The proposed changes do not necessitate a physical alteration of the plant (no new or different type of equipment will be installed) or changes in parameters governing normal plant operations. The proposed changes will not impose any different requirements.
Less Restrictive - Administrative Deletion of Requirements The proposed change does not necessitate a physical alteration of the plant (no new or different type of equipment will be installed) or changes in parameters governing normal plant operations. The proposed changes will not impose any different requirements and adequate control of the information will be maintained.

- 1) A note will be added that allows three (3) hours to perform the channel functional test on the control room radiation monitors without entering the associated Actions.
The proposed change does not necessitate a physical alteration of the plant (no new or different type of equipment will be installed) or changes in parameters governing normal plant operation. The proposed change will still ensure proper surveillances are required for the equipment considered in the safety analysis. Thus, this change does not create the possibility of a new or different kind of accident from any accident previously evaluated.

The proposed change does not necessitate a physical alteration of the unit (no new or different type of equipment will be installed) or changes in parameters governing normal unit operation.

- 3) An allowance will be added to allow use of a "simulated" or uactual" signal when testing the automatic isolation feature of the control room air filtration system.
The possibility of a new or different kind of accident from any accident previously evaluated is not created because the proposed change introduces no new mode of plant operation and it does not involve physical modification to the plant.

- 3. Do the proposed changes involve a significant reduction in a margin of safety?
Response: No.
to Letter#
Page 19 of 22 Administrative Chanes:
The proposed changes will not reduce the margin of safety because they have no impact on any safety analysis assumptions. The changes are administrative in nature.
Less Restrictive - Administrative Deletion of Requirements The proposed changes will not reduce a margin of safety because they have no impact on any safety analysis assumptions. In addition, the requirements to be transposed from the TSs to other license basis documents, which are under licensee control, are the same as the exiting TSs. The documents containing the relocated requirements will be maintained using the provisions of applicable regulatory requirements.
More Restrictive Changes The imposition of more stringent requirements prevents a reduction in the margin of plant safety by:
a) increasing the scope of the specification to include additional plant equipment, b) providing additional actions, c) decreasing restoration times, or d) imposing new surveillances.
The changes are consistent with the safety analysis and licensing basis.
Less Restrictive Changes
- 1) A note will be added that allows three (3) hours to perform the channel functional test on the control room radiation monitors without entering the associated Actions.
The margin of safety for the control room area radiation monitor is based on availability and capability of the instrumentation to provide the required information to the operator. The frequency is based on unit operating experience that demonstrates channel failure is rare, and on the use of less formal but more frequent checks of channels during normal operational use of the displays associated with the required channels. Therefore, the availability and capability of the control room area radiation monitor continues to be assured by the proposed Surveillance Requirements and this change does not involve a significant reduction in a margin of safety.
- 2) This change will allow the control room boundary to be opened intermittently under administrative controls, and will allow both trains of the control room ventilation system (CREVS) to be inoperable due to control room boundary inoperability for a period of 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br />.
This change does not involve a significant reduction in a margin of safety since: 1) administrative controls will be in place to ensure that an open control room boundary can be rapidly closed when a need for control room isolation is indicated; and 2) an inoperable control room boundary that renders both trains of CREVS inoperable is an infrequent occurrence, the probability of an accident requiring control room isolation to Letter #
Page 20 of 22 during any given 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> period is low, and preplanned compensatory measures to protect the control room operators from potential hazards are implemented.
- 3) An allowance will be added to use a simulated or actual signal when testing the automatic isolation feature of the control room air filtration system.
Use of an actual signal instead of the existing requirement which limits use to a simulated signal, will not affect the performance of the surveillance test.
OPERABILITY is adequately demonstrated in either case since the system itself can not discriminate between "actual" or "simulated" signals. Therefore, the change does not involve a significant reduction in a margin of safety.
- 4) An allowance for the diesel fuel storage tanks to contain less than 22,500 gallons of fuel for up to 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> as long as the individual volume is greater than 17,446 gallons. The lower value when'summed with the contents of the other tank ensures six days of fuel oil is available. During the 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br />, the diesel generator is capable of performing its intended function. There is a low probability that an event would occur for which the diesel generator would be required during this short period of time when the lower fuel oil volume is allowed.
The parameter limits provide substantial margin to the parameter values that would be absolutely necessary for diesel generator operability. When the parameters are less than their limits this margin is reduced. However, the availability of AC Sources continues to be assured since the allowed time for parameters to be less than their limits is short and the allowed levels for the parameters are adequate to provide the immediately needed power availability. Further, the parameters can be restored to within limits during the proposed time provided should they be required. Therefore, this change does not result in a signification reduction in margin of safety.
- 5) Seven days will be allowed to restore the stored diesel fuel oil total particulates to within the required limits prior to declaring the associated diesel inoperable.
The proposed change allows the stored diesel fuel oil total particulates to be outside
.the required limits for seven days before declaring the associated diesel inoperable.
The presence of particulates does not mean failure of the fuel oil to bum properly in the diesel engine. In addition, particulate concentration is unlikely to change significantly between surveillance intervals (31 days). The seven day allowance provides an appropriate backstop to ensure the particulate level is restored to within limits in a reasonable time period. Since the diesel is still capable of performing its function the margin to safety is not reduced.
- 6) An allowance for the person who is satisfying the requirement of the radiation protection staff position and for the person filling the Shift Technical Advisor (STA) position to be vacant for not more than two hours in order to provide for unexpected absences is proposed. This is consistent with the allowance permitted for the control room operator as reflected in existing TSs.
The margin of safety is not dependent on the presence of the STA or the radiation protection technician. Therefore, this change does not involve a significant reduction in a margin of safety.
to Letter #
Page 21 of 22
- 7) The STA will be allowed to support the shift crew rather than only the shift supervisor. This provides more flexibility and does not dilute the function of the STA.
The margin of safety is not dependent upon who the STA supports. Therefore, this change does not involve a significant reduction in a margin of safety.
- 8) The Occupational Radiation Exposure Report will be submitted by April 30 of each calendar year instead of prior to March 1.
The margin of safety is not dependent on the submittal of information. Therefore, this change does not involve a significant reduction in a margin of safety.
- 9) An allowance is proposed that will revise the high radiation areas to include additional previously approved methods for implementation of alternatives to the "control device' or alarm signal" requirements of 10 CFR 20. These alternatives provide adequate control of personnel in high radiation areas as evidenced by NRC issuance of NUREG-1432.
The requirements for control of high radiation areas provide for the use of alternates to the control device orualarm signal" requirements of 10 CFR 20.1601. This change provides such alternative methods for controlling access. These methods and additional administrative requirements have been determined to provide adequate controls to prevent unauthorized and inadvertent access to such areas. Therefore, this change does not involve a significant reduction in a margin of safety.
- 10) An allowance to require periodic testing of stored fuel for the particulates only is proposed.
The testing of stored diesel generator fuel oil is revised to require the periodic testing of the stored fuel oil only for particulates (replacing the periodic testing per ASTM-D975) once every 31 days. The change reflects industry-standard acceptable DG fuel oil testing programs. Over the storage life of ANO-2 DG fuel oil, the properties tested by ASTM-D975 are not expected to change and performing these tests once on the new fuel oil provides adequate assurance of the proper initial quality of fuel oil. The periodic testing for particulates monitors a parameter that reflects degradation of fuel oil and can be trended to provide increased confidence that the stored DG fuel oil will support DG operability. Therefore, this change does not involve a significant reduction in a margin of safety.
- 11) The removal of the requirement to notify the Vice President, Operations ANO within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> of violating a safety limit.
The margin of safety is not dependent upon notification of the Vice President, Operations ANO upon the violation of a TS safety limit. Therefore, the proposed change does not involve a significant reduction in a margin of safety.
- 12) The Radioactive Effluent Release Report will be submitted by May 1 of each calendar year instead of prior to March 1.

13)A change that allows a 25% extension of the frequency in accordance with SR 4.0.2 for the integrated leak tests of each system outside containment that could contain highly radioactive fluids.
The proposed allowance allows a possible increase in performance interval.
However, the test will still be performed at reasonable intervals to ensure the intent of the surveillance is maintained. Therefore, this change does not involve a significant reduction in a margin of safety.
14)A change that allows the OSRC review of the desirability of maintaining a channel in the bypassed condition to be at or before the next regularly scheduled meeting.
The proposed change allows the OSRC review to occur earlier than previously required if an OSRC meeting is called before the next regularly scheduled meeting.
Therefore, the proposed change does not involve a significant reduction in a margin of safety.
