Joseph M. Farley Nuclear Plant Request for Technical Specifications Amendment Containment Tendon Surveillance Program Basis for the Proposed Change
Joseph M. Farley Nuclear Plant Request for Technical Specifications Amendment Containment Tendon Surveillance Program Enclosure I Basis for the Proposed Change 1.0 Description The proposed change revises the Farley Nuclear Plant (FNP) Units I and 2 Technical Specifications (TS) 5.5, "Programs and Manuals," TS 5.6, "Reporting Requirements," and TS Bases for LCO 3.6.1, "Containment," to reflect the latest requirements for tendon surveillance. The proposed changes are a result of the NRC issuing a final rule amending 10 CFR 50.55a that affected the surveillance methods for the containment tendons and the conduct of containment visual inspections, and the methods of reporting the results of the required inspections to the NRC. These revised requirements were to be fully implemented by September 9, 2001.
2.0 Proposed Change The following change (in italics) is proposed for the last sentence of the first paragraph in TS section 5.5.6, "Pre-Stressed Concrete Containment Tendon Surveillance Program:"
"The Tendon Surveillance Program, inspection frequencies, and acceptance criteria shall be in accordance with Section Xl Subsection I`WL of tie ASME Boiler and Pressure Vessel Code and applicable addenda as required bya IO CFR 50.55a, except where an alternative, exemption or relief has been authorized by the NRC Tie first performance of the lWL requirements for containment sample tendon force measurements and tendon wire and strand sample examinations will be performed by the end of2006."
In addition, since the tendon inspection frequencies will be in accordance with ASME Section XI, Subsection IWL, the provisions of SR 3.0.2 are no longer applicable; therefore, deletion of the provisions of SR 3.0.2 from Technical Specification 5.5.6 is also proposed. 10 CFR 50.55a requires the implementation of ASME Section Xl, Subsection IWL and specifies the requirements for extending inspection frequencies.
Also, since reporting requirements for the Tendon Surveillance Report will be in accordance with the reporting requirements in 10 CFR 50.55a, deletion of the provisions of Technical Specification 5.6.9 is also proposed. Repeating the Federal Regulations within the TS is not necessary to ensure safe operation of the plant.
Therefore, the deletion of this TS requirement is acceptable.
The following change (in italics) is proposed for the last sentence in TS Bases for LCO 3.6.1, "Containment," SR 3.6.1.2:
"Testing and Frequency are consistent with the requirements of Section XI, Subsection IWVL of the ASME Boiler and Pressure Vessel Code and applicable
Joseph M. Farley Nuclear Plant Request for Technical Specifications Amendment Containment Tendon Surveillance Program Enclosure I addenda as required by 10 CFR 50.55a, except where an alternative, exrenption or relief has been authorized by the NRC (Ref. 4). "
The following change (in italics) is proposed for TS Bases for LCO 3.6.1, "Containment," in the "References" section:
Revise reference #4 to: Section Xl Subsection IIL of the ASME Boiler and Pressure Vessel Code and applicable addenda as required by IO CFR 50.55a.
The current TS and TS Bases refer to Regulatory Guide 1.35, Revision 2.
3.0
Background
Prior to September 26, 2000, post tensioning exams conducted at Farley Nuclear Plant (FNP) were performed in accordance with Regulatory Guide (RG) 1.35, Rev.
2 in accordance with the plant Technical Specifications.
Since both FNP units had similar containments, RG 1.35, Rev. 2 allowed containment sample tendon force measurements and tendon wire and strand sample examinations to be performed every 5 years (based on the Structural Integrity Test (SIT) date) on Unit I only. Visual examinations and exams for water at the corrosive protective medium were required on the tendon anchorage area for each unit every 5 years.
Containment sample tendon force measurements and tendon wire and strand sample (full) examinations were performed on Unit I in 1978 (I year exams), 1980 (3 year exams), 1982 (5 year exams), 1987 (10 year exams) and in 1992 (15 year exams).
The next examination was due in 1997 (20 year exams). Visual examinations and exams for water at the corrosive protective medium were performed every five years on each unit as required.
A rule change to I OCFR 50.55a dated August 8, 1996, required licensees to perform expedited Containment examinations in accordance with the 1992 edition and addenda of Section XI, Subsection IWL. The expedited examination schedule required the first exams be completed by September 9, 2001. However, for containment sample tendon force measurements and tendon wire and strand sample examinations, the rulemaking gave licensees the option to perform the expedited examinations (i.e. exams performed between September 9, 1996 and September 9, 2001) in accordance with a program that was approved by the NRC prior to September 9, 1996 (e.g., the Technical Specifications).
FNP elected to continue with the Technical Specification/RG 1.35 examinations and performed the 20 year Unit I containment sample tendon force measurements and tendon wire and strand sample examinations in 1997. All acceptance criteria were met. The next required examination for Unit I was in 2002 (25 year exams).
Joseph M. Farley Nuclear Plant Request for Technical Specifications Amendment Containment Tendon Surveillance Program On September 26, 2000 the Containment Inspection Plan, which is the scheduling device for performing FNP Containment exams, was revised to incorporate the requirements of IWL. This revision deleted the TS/RG 1.35 schedule; however, the TS (SR 3.6.1.2 and TS 5.5.6) were not changed, thus they remained in effect.
IWL-2420(a) required containment sample tendon force measurements and tendon wire and strand sample examinations on each unit every 5 years (based on SIT).
Visual examinations and exams for water were required on the tendon anchorage area for each unit every 5 years per IWL-2420. For the 10 year and subsequent examinations, IVL-2420(c) allows examinations to be scheduled +/- I year from the specified schedule date. Visual examinations were performed in 2000 on FNP Unit 2 and in 2002 on FNP Unit 1. For each of these surveillances, all acceptance criteria were met.
However, IWL-2421 provided an option that allowed extending containment sample tendon force measurements and tendon wire and strand sample examinations on both units to a 10 year frequency if both are similar and if both post tensioning operations were completed not more than 2 years apart. Visual examinations and exams for water at the corrosive protective medium are required on the tendon anchorage area for each unit every 5 years.
At FNP, the post tension operations were performed 26 months apart. Therefore, the IWL-242 1(a) requirements were not met. Even though this exceeds the requirements of IWL-242 1(a) for applying IWL-242 1(b) by 2 months, exceeding the post tensioning operations required time by only 2 months does not present any safety or technical concerns because a 2 month difference is insignificant. Both units share the same design, were under construction during the same time period in a sequential manner, and are exposed to virtually identical environmental conditions. However, FNP inappropriately interpreted the allowance of IWL-2421 (a) and elected to use the IWL-2421 (b) option and deferred the Unit 1 25 year containment sample tendon force measurements and tendon wire and strand sample examinations due in 2002 until 2007 (30 year exams) instead of performing them in 2002 as required by IWL-2420. In addition, since the TS still referenced RG 1.35, Rev. 2 as the basis for the Pre-Stressed Concrete Containment Tendon Surveillance Program (TS 5.5.6), and RG 1.35, Rev. 2 required an examination in 2002 as well, TS SR 3.6.1.2 was missed.
TS 5.5.6 states that SR 3.0.3 is applicable to the Tendon Surveillance Program inspection frequencies. SR 3.0.3 states that if it is discovered that a Surveillance was not performed within its specified Frequency, then compliance with the requirement to declare the LCO not met may be delayed, from the time of discovery, up to 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> or up to the limit of the specified Frequency, whichever is greater. This delay period is permitted to allow performance of the Surveillance. A risk evaluation shall be performed for any Surveillance delayed greater than 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> and the risk impact shall be managed. In addition, the Bases state that all missed Surveillances will be placed in the licensee's Corrective Action Program.
FNP has completed a qualitative risk evaluation with regard to the risk of delaying the missed examination and has documented the evaluation in its Corrective Action
Joseph M. Farley Nuclear Plant Request for Technical Specifications Amendment Containment Tendon Surveillance Program Enclosure I Program. The risk evaluation concluded that it is acceptable from a risk perspective to delay the performance of the containment sample tendon force measurements and tendon wire and strand sample examinations for Unit I until the planned performance in 2006.
SNC has submitted in letter NL-05-0285 a request for alternative, RR-57, requesting permission from the NRC to use the 10 year scheduling option (even though the post tensioning operations were performed slightly greater than 2 years apart). This option will allow FNP to use the IWL-242 1(b) inspection requirements for two site containments whose post tensioning operations were completed not more than 2 years apart. In addition, letter NL-05-0285 includes a request for alternative, RR-58, regarding future IWL containment examination dates based on a common administrative date of July 2006 for both FNP units.
The scope of this proposed change updates the TS and TS Bases to reflect the latest requirements of the Containment Tendon Surveillance Program that FNP has incorporated into its ISI program.
4.0 Regulatorv Analysis No Sig!nificant Hazards Consideration The proposed change revises the Farley Nuclear Plant (FNP) Units I and 2 Technical Specifications (TS) 5.5, "Programs and Manuals," TS 5.6, "Reporting Requirements," and TS Bases for LCO 3.6.1, "Containment," to reflect the latest requirements for tendon surveillance. Since the tendon inspection frequencies will be in accordance with American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code (ASME Code)Section XI, Subsection IWL, the provisions of SR 3.0.2 are no longer applicable and are deleted from Technical Specification 5.5.6. 10 CFR 50.55a requires the implementation of ASME Section XI, Subsection INVL and specifies the requirements for extending inspection frequencies.
In TS 5.5.6, reference to the first performance of the INVL requirements for containment sample tendon force measurements and tendon wire and strand sample examinations to be performed by the end of 2006 is proposed. In addition, since reporting requirements are contained in 10 CFR 50.55a, deletion of the provisions of Technical Specification 5.6.9 is proposed. Repeating the Federal Regulation within the TS is not necessary to ensure safe operation of the plant. Therefore, the deletion of this TS requirement is acceptable. Also, several editorial changes in the TS are proposed.
Southern Nuclear Operating Company (SNC) has evaluated whether or not a significant hazards consideration is involved with the proposed change by focusing on the three standards set forth in 10 CFR 50.92, "Issuance of Amendment," as discussed below:
Joseph M. Farley Nuclear Plant Request for Technical Specifications Amendment Containment Tendon Surveillance Program Enclosure I
- 1. The proposed license amendment does not involve a significant increase in the probability or consequences of an accident previously evaluated.
The proposed change replaces the previous TS requirement to implement a Containment Tendon Surveillance Program based on Regulatory Guide 1.35, Rev. 2, with a Containment Inspection Program that complies with the current requirements of 10 CFR 50.55a. This regulation requires licensees to implement a Containment Inspection Program in compliance with the 1992 Edition with the 1992 Addenda of Subsection IWE, "Requirements for Class MC and Metallic Liners of Class CC Components of Light-Water Cooled Plants," and with Subsection IWL, "Requirements for Class CC Concrete Components of Light-Water Cooled Plants," of Section XI, Division 1, of the American Society of Mechanical Engineers Boiler and Pressure Vessel Code (ASME Code) with additional modifications and limitations as stated in 10 CFR 50.55a(b)(2)(ix). SNC has implemented a Containment Inspection Program that complies with the regulatory requirements. This proposed TS amendment is requested to update the TS to the latest 10 CFR 50.55a regulatory requirements.
In addition, reporting requirements that are redundant to existing regulations are deleted, minor editorial changes are made, and the applicability of SR 3.0.2 to the tendon surveillance program is deleted since surveillance frequencies and associated extensions are specified in ASME Section XI, Subsection IWL.
By complying with the regulatory requirements described in 10 CFR 50.55a, the probability of a loss of containment structural integrity is maintained as low as reasonably achievable. Maintaining containment structural integrity as described in the revised Containment Inspection Program does not impact the operation of the reactor coolant system (RCS), containment spray (CS) system, or emergency core cooling system (ECCS). The Containment Inspection Program ensures that the containment will function as designed to provide an acceptable barrier to release of radioactive materials to the environment. The proposed change does not alter or prevent the ability of structures, systems, and components (SSCs) from performing their intended function to mitigate the consequences of an initiating event within the assumed acceptance limits.
The proposed change does not impact any accident initiators or analyzed events, nor does it impact the types or amounts of radioactive effluent that may be released offsite. Therefore, the proposed change does not involve a significant increase in the probability or consequences of an accident previously evaluated.
- 2. The proposed license amendment does not create the possibility of a new or different kind of accident from any accident previously evaluated.
Maintaining containment structural integrity does not impact the operation of the RCS, CS system, or ECCS. The proposed change does not involve a modification to the physical configuration of the plant or a change in the methods governing normal plant operation. The proposed change does not
Joseph M. Farley Nuclear Plant Request for Technical Specifications Amendment Containment Tendon Surveillance Program Enclosure I introduce a new accident initiator, accident precursor, or malfunction mechanism. Therefore, the proposed change does not create the possibility of a new or different kind of accident from any accident previously evaluated.
- 3. The proposed license amendment does not involve a significant reduction in a margin of safety.
By complying with the regulatory requirements described in 10 CFR 50.55a, the probability of a loss of containment structural integrity is maintained as low as reasonably achievable. The Containment Inspection Program ensures that the containment will function as designed to provide an acceptable barrier to release of radioactive materials to the environment. The proposed change does not adversely affect plant operation or existing safety analyses. Therefore, the proposed change does not involve a significant reduction in a margin of safety.
5.0 Environmental Considerations SNC has reviewed the proposed change pursuant to 10 CFR 50.92 and determined that it does not involve a significant hazards consideration. In addition, there is no significant change in the types or significant increase in the amounts of any effluents that may be released offsite, and there is no significant increase in individual or cumulative occupational radiation exposure. Consequently, the proposed TS change has no significant effect on the human environment and satisfies the criteria of 10 CFR 51.22 for categorical exclusion from the requirements for an environmental assessment.

- b.
Performance criteria for SG tube integrity. SG tube integrity shall be maintained by meeting the performance criteria for tube structural integrity, accident induced leakage, and operational LEAKAGE.
- 1. Structural integrity performance criterion: All inservice SG tubes shall retain structural integrity over the full range of normal operating conditions (including startup, operation in the power range, hot standby and cooldown and all anticipated transients included in the design specification) and design basis accidents. This includes retaining a safety factor of 3.0 (3AP) against burst under normal steady state full power operation primary to secondary pressure differential and a safety factor of 1.4 against burst applied to the design basis accident primary to secondary pressure differentials. Apart from the above requirements, additional loading conditions associated with the design basis accidents, or combination of accidents in accordance with the design and licensing basis, shall also be evaluated to determine if the associated loads contribute significantly to burst or collapse. In the assessment of tube integrity, those loads that do significantly affect burst or collapse shall be determined and assessed in combination with the loads due to pressure with a safety factor of 1.2 on the combined primary loads and 1.0 on axial secondary loads.
- 2.
Accident induced leakage performance criterion: The primary to secondary accident induced leakage rate for any design basis accident, other than a SG tube rupture, shall not exceed the leakage rate assumed in the accident analysis in terms of total leakage rate for all SGs and leakage rate for an individual SG. Accident induced leakage is not to exceed 1 gpm total for all three SGs.
- 3.
