Watts Bar Nuclear Plant (WBN) Unit 2 - Supplemental Information For Review of Developmental Revision A of the Unit 2 Technical Specifications (TS) and Technical Specifications Bases (TS Bases)
TVAs letter to NRC dated March 4, 2009 (Reference 1), included Developmental Revision A of the Unit 2 TS and TS Bases. Enclosure 2 of that letter noted that the proposed WBN Unit 2 TS and TS Bases were developed by marking up Revision 0 of NUREG-1431, Standard Technical Specifications Westinghouse Plants, to indicate the WBN Unit 1 TS and TS Bases approved (as appropriate) through Amendment 70 and Revision 91, respectively.
Recently, an NRC staff member noted that the current licensing basis for Unit 1 was to be used as the reference basis for the review and licensing of Unit 2. Based on this, the staff member noted that the Developmental A versions of the TS and TS Bases should have been based on the Unit 1 TS amendment and TS Bases revision that were current when the first WBN Regulatory Framework letter was issued for Unit 2. As a result, the staff requested that a markup of these versions of the TS and TS Bases (i.e., when the framework letter was submitted) be provided that reflects the Unit 1 TS amendment and TS Bases revision that were current when Developmental Revision A of the Unit 2 TS and TS Bases was submitted.
To accomplish this activity, this letter provides the following:
x Enclosure 1 describes the process used to produce the requested markups of the TS and TS Bases. Additionally, the review matrix used for the markups is discussed.
x Enclosure 2 includes the TS Review Matrix and the associated marked-up TS pages.
x Enclosure 3 includes the TS Bases Review Matrix and the associated marked-up TS Bases pages.

ENCLOSURE 1 Process for Marking Up the Technical Specifications (TS) and TS Bases Pages Tennessee Valley Authority - Watts Bar Nuclear Plant - Unit 2, Docket No. 50-391 See Page 3 of the cover letter for references.
Developmental Revision A of the Unit 2 TS and TS Bases (Reference 1) were based on Revision 0 of NUREG-1431, Standard Technical Specifications Westinghouse Plants.
Developmental Revision A was constructed by starting with NUREG-1431 and then overlaying the Unit 1 TS amendments and TS Bases revisions made from Amendment 0 / Revision 0 through Amendment 70 / Revision 91, respectively.
The NRC staff reviewer has requested that an alternate markup be provided which is based on the versions of the Unit 1 TS and TS Bases which were current at the time of the first WBN Unit 2 regulatory framework letter (Reference 2). At that time, the Unit 1 TS and TS Bases were at Amendment 67 and Revision 86, respectively. Therefore, the attached markups depict the applicable changes from the date of Reference 2 to the date of Reference 1 (i.e., January 29, 2008, to March 4, 2009). Thus, the markups herein address Unit 1 TS Amendments 68 through 70 and TS Bases Revisions 87 through 91. Unit 1 TS Amendment 69 was found to be a temporary change that is not needed for Unit 2; thus, it is not included in the markup provided in Enclosure 2. Additionally, as noted below, some of the Unit 1 TS amendments and TS Bases revisions prior to Amendment 67 and Revision 86, respectively, will not apply to Unit 2 (e.g.,
Unit 2 will not utilize a tritium producing core).
Changes to the Unit 2 TS and TS Bases made after the date of Reference 1 are addressed by References 3 through 6.
The markups contained in this letter result in basically the same TS and TS Bases as provided in Reference 1 except for the discrepancies noted in Enclosure 4.
The requested markups provided in Enclosures 2 and 3 involve only the affected pages that resulted from the process described below:
For the TS:
x Marked up the applicable Unit 1 TS pages to show the changes that resulted from Unit 1 TS Amendments 68 and 70 (i.e., the amendments incorporated between the submittal of References 1 and 2).
x Designated the Unit 1 TS amendments that were not incorporated on Unit 2. Where appropriate, provided a markup to show how the TS looked prior to incorporation of the amendment that was not incorporated.
x Provided a review matrix for the TS. This matrix indicates, by TS section, which amendments were incorporated and which amendments were not incorporated. This matrix also delineates when / why a markup is not provided.

ENCLOSURE 3 Unit 2 TS Bases Review Matrix: Unit 1 Revisions 86 through 91 With Associated Markups Tennessee Valley Authority - Watts Bar Nuclear Plant - Unit 2, Docket No. 50-391
ENCLOSURE 4 Discrepancies Identified During the Process of Marking Up the TS and TS Bases Tennessee Valley Authority - Watts Bar Nuclear Plant - Unit 2, Docket No. 50-391
- 1. Affected sections: TS 3.3.1 and 3.4.1; TS Bases 3.3.1 and 3.4.1
Background:
Unit 1 TS Amendment 47 amended the Unit 1 TS to allow an alternate method for the measurement of RCS total flow rate via measurement of the RCS elbow tap differential pressures. Unit 1 TS Bases Revision 60 revised the Unit 1 TS Bases to implement the changes made by Amendment 47.
The review matrix for Developmental Revision A stated the following for each section:
x TS 3.3.1: The changes will be applied to Unit 2.
x TS Bases 3.3.1: The changes will be applied to Unit 2.
x TS 3.4.1: The changes will be applied to Unit 2.
x TS Bases 3.4.1: The changes will be applied to Unit 2.
Discrepancy:
The changes should not have been incorporated in Developmental Revision A of the Unit 2 TS and TS Bases because the elbow tap differential pressure measurement method is not being used on Unit 2.
Corrective Action(s):
Developmental Revision B of the Unit 2 TS and TS Bases deleted the changes incorporated per Unit 1 TS Amendment 47 / Unit 1 TS Bases Revision 60. No further corrective action is required.
- 2. Affected section: TS Bases 3.6.9
Background:
Unit 1 TS Bases Revision 71 revised the Unit 1 TS Bases to reflect changes to the Unit 1 TS approved by Unit 1 TS Amendment 59 (support steam generator replacement by allowing TEMPORARY use of penetrations in Shield Building Dome during Modes 1-4).
The review matrix for Developmental Revision A stated, This change will NOT be applied to Unit 2.
Discrepancy:
Contrary to the above, a minor portion of Unit 1 TS Bases Revision 71 (i.e., "See TS Bases 3.6.15, Shield Building, for additional information on EGTS.") was incorporated into Developmental Revision A of the Unit 2 TS Bases.
E4-1
ENCLOSURE 4 Discrepancies Identified During the Process of Marking Up the TS and TS Bases Tennessee Valley Authority - Watts Bar Nuclear Plant - Unit 2, Docket No. 50-391 Corrective Action:
Since this wording is nothing more than an aid to indicate where additional information on EGTS can be found, leaving this statement in the Unit 2 TS Bases has no impact on the Bases.
The wording will be left in the Unit 2 TS Bases; no further corrective action is required.
- 3. Affected section: TS section 3.7.1
Background:
Unit 2 TS Amendment 31 amended the Unit 1 TS to approve Power Uprate using Leading Edge Flow Meter (LEFM).
The review matrix for Developmental Revision A stated, This change will NOT be implemented on Unit 2 at this time.
Discrepancy:
Contrary to this statement, the "58%" value in REQUIRED ACTION A.1 should have remained at "59%."
Corrective Action:
A future Developmental Revision to the Unit 2 TS will correct the "58%" value in TS LCO 3.7.1, REQUIRED ACTION A.1 to "59%."
- 4. Affected section: TS Bases 3.8.1
Background:
Unit 1 TS Bases Revision 50 revised the Unit 1 TS Bases to reflect changes to the Unit 1 TS approved by Unit 1 TS Amendment 39 (revise LCO 3.8.1's allowed outage time to restore an inoperable emergency diesel generator to operable status from 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> to 14 days).
The review matrix for Developmental Revision A stated, This change will NOT be applied to Unit 2.
Discrepancy:
Contrary to the above, the version showing the changes incorporated for Unit 2 TS Bases 3.8.1 that was provided in Developmental Revision A of the Unit 2 TS Bases included the following verbiage at the end of SR 3.8.1.14:
"Prior to performance of this SR in Modes 1 or 2, actions are taken to establish that adequate conditions exist for performance of the SR. The required actions are defined in Bases Table 3.8.1-2."
E4-2
ENCLOSURE 4 Discrepancies Identified During the Process of Marking Up the TS and TS Bases Tennessee Valley Authority - Watts Bar Nuclear Plant - Unit 2, Docket No. 50-391 This verbiage was not shown in the markup provided for Developmental Revision A of the Unit 2 TS Bases, and should NOT have been incorporated. Table 3.8.1-2 was not added by the markup, and it was not incorporated.
Corrective Action:
A future Developmental Revision to the Unit 2 TS Bases will remove the above wording from the TS Bases for SR 3.8.1.14.
E4-3
ENCLOSURE 5 Commitments Tennessee Valley Authority - Watts Bar Nuclear Plant - Unit 2, Docket No. 50-391
- 1. A future Developmental Revision to the Unit 2 TS will correct the "58%" value in Unit 2 TS LCO 3.7.1, REQUIRED ACTION A.1 to "59%."
- 2. A future Developmental Revision to the Unit 2 TS Bases will remove the "Prior to performance of this SR in Modes 1 or 2, actions are taken to establish that adequate conditions exist for performance of the SR. The required actions are defined in Bases Table 3.8.1-2." wording from the TS Bases for SR 3.8.1.14.
