REFERENCE:

(1) NRC Letter to Michael Kansler, "Relief Request No. RR-39, Implementation of BWRVIP Guidelines in Lieu of ASME Section Xl Code Requirements on Reactor Vessel Internals and Components (TAC No. MC8587), dated August 30, 2006.(2) Vermont Yankee Relief No. R1 -01, dated September 19, 2005 (TAC No. MC0960)LETTER NUMBER: 2.08.008

Dear Sir or Madam:

Pursuant to 10 CFR 50.55a(a)(3)(i), Entergy submits the attached Pilgrim Relief Request, PRR-16 (Attachment

1) for NRC approval to implement various Boiling Water Reactor Vessel Internals Program (BWRVIP) Guidelines in lieu of the American Society of Mechanical Engineers (ASME) Section X1 Code Inspection Requirements on reactor vessel internals and components.

Pilgrim Nuclear Power Station (PNPS) requests relief from the Inservice Inspection (ISI)Program requirements of the ASME Boiler and Pressure Vessel Code,Section XI, 1998 Edition, 2000 Addenda. The request applies to reactor vessel internals and components, and includes the technical basis for relief on each applicable component, or group of components.

Attachment 2 is a comparison of the ASME Examination Requirements and the BWRVIP Guideline requirements.

Attachment 3 is the reactor internals inspection history, including the most recent refueling outage (RFO16, Spring 2007). Attachment 4 is a list of the applicable components in the Pilgrim Reactor Vessel Internals Inspection Program and the number of welds for these components.

Additionally, the ASME Code does not have specific inspection requirements for the steam dryer. Entergy will use the guidelines in BWRVIP-139, "BWRVIP Steam Dryer Inspection and Flaw Evaluation Guidelines" for the steam dryer inspections.

Entergy has concluded that this proposed alternative will ensure that the integrity of the reactor vessel internal components is maintained with an acceptable level of quality and safety./6q7 Entergy Nuclear Operations, Inc.Pilgrim Nuclear Power Station Letter No. 2.08.008 Page 2 A similar relief request was approved for Entergy's James A.

These examinations are included in Table IWB-2500-1, Examination Categories B-N-1 and B-N-2 and are identified with the following item numbers: B13.10 Examine accessible areas of the reactor vessel interior each period by the VT-3 method.B13.20 Examine interior attachment welds within the beltline region each interval by the VT-1 method.B13.30 Examine interior attachment welds beyond the beltline region each interval by the VT-3 method.B13.40 Examine surfaces of the core support structure each interval by the VT-3 method.These examinations are performed to assess the structural integrity of components within the boiling water reactor pressure vessel.Page 1 of 8 Attachment 1 To Entergy Letter No. 2.08.008 (PRR-16)4.0 Reason for Request To conserve radiological exposure and reduce outage duration while still maintaining an adequate level of quality and safety for the examination of the reactor vessel internals and welds.5.0 Proposed Alternative In lieu of the requirements of ASME Section XI, 1998 Edition, 2000 Addenda, the proposed alternative described herein shall be used.Entergy will examine components within the reactor vessel in accordance with BWRVIP Guideline requirements, unless otherwise noted. The particular guidelines that are applicable to those components are:* BWRVIP-18-A, "BWRVIP Core Spray Internals Inspection and Flaw Evaluation Guidelines"* BWRVIP-25, "BWRVIP Core Plate Inspection and Flaw Evaluation Guidelines"* BWRVIP-26-A, "BWRVIP Top Guide Inspection and Flaw Evaluation Guidelines"* BWRVIP-27-A, "BWRVIP BWR Standby Liquid Control System/Core Plate delta P Inspection and Flaw Evaluation Guidelines"* BWRVIP-38, "BWRVIP Shroud Support Inspection and Flaw.Evaluation Guideline"* BWRVIP-41, Revision 1, "BWRVIP Jet Pump Assembly Inspection and Flaw Evaluation Guidelines"* BWRVIP-47-A, "BWR Lower Plenum Inspection and Flaw Evaluation Guidelines"* BWRVIP-48-A, "Vessel ID Attachment Weld Inspection and Flaw Evaluation Guidelines"* BWRVIP-76, "BWR Core Shroud Inspection andFlaw Evaluation Guidelines"* BWRVIP-138, "BWRVIP Updated Jet Pump Beam Inspection and Flaw Evaluation Guidelines" Attachment 2 compares the required ASME Category B-N-1 and B-N-2 examination requirements with the above current BWRVIP Guideline requirements that are applicable to PNPS. Attachment 3 is a summary of PNPS reactor internals inspection history, including results from the last inspections performed during the most recent refuel outage (RFO16 Spring 2007). Attachment 4 identifies the applicable component in the reactor internal inspection program and the total number of welds in each component.

In addition, the requirements of BWRVIP-94, Revision 1 "Program Implementation Guide", will be followed.

BWRVIP-94, Revision 1 states that where guidance in existing BWRVIP documents has been supplemented or revised by subsequent correspondence approved by the BWRVIP Executive Committee, the most current approved guidance will be implemented.

Therefore, the attached Table only represents a most current comparison.

Page 2 of 8 Attachment 1 To Entergy Letter No. 2.08.008 (PRR-16)6.0 Basis for Use These BWRVIP Guidelines were developed and maintained to provide guidance in the examination of BWR internals and components.

These Guidelines have been written to address the safety significant vessel internal components and to examine these components using appropriate methods and re-examination frequencies.

The NRC has agreed with the BWRVIP approach in principle and has previously issued Safety Evaluations for these guidelines (see References).

The technical basis for the proposed alternative inspection of each component, or group of components, is discussed in the following paragraphs by Code Subsections.

Each section includes several examples of a component or weld that belong in each Code Subsection.

6.1 B13.10, Reactor Vessel Interior Accessible Areas B-N-1 The ASME Section Xl Code requires a VT-3 examination of reactor vessel interior surfaces made accessible every three and a third (3 1/3) years during each 10 year interval.

This is a non-specific inspection requiring examination of surfaces made accessible during refueling.

The various BWRVIP Inspection and Evaluation guidelines require, as a minimum, a VT-3 inspection of reactor vessel interior components.

Additionally, the BWRVIP guidelines require that many component welds and weld heat affected zones in this category be inspected by a VT-1, EVT-1, or UT examination method. The BWRVIP inspection method meets (VT-3) or exceeds (VT-1, EVT-1, or UT) the inspection method requirement specified by the ASME Code.The Core Spray piping and sparger are used as examples for comparison between the ASME Code and the BWRVIP inspection requirements.

BWR Core Spray Internals Inspection and Flaw Evaluation Guideline (BWRVIP-18-A)

• The Section Xl Code requires a VT-3 each period (3 1/3 years) of each 10 year interval of the Core Spray internal piping and sparger accessible surfaces.The BWRVIP requires either an EVT-1 of the core spray pipe creviced welds and weld heat affected zones each refuel outage (2 year) along with 25% of the non creviced weld locations on a rotated basis or UT. If UT is performed on the creviced weld locations, then the frequency is every other outage (4 years).100% of the pipe brackets are inspected by EVT-1 every 4 outages (8 years).100% of the major Core Spray sparger welds require an EVT-1 inspection every other outage (4 years). 50% of the other Core Spray sparger welds require a VT-1 inspection every other outage (4 years). 100% of the sparger bracket welds are inspected by VT-I every 2 outages (4 years).The BWRVIP inspection methods are superior to the ASME Code inspection methods.The BWRVIP specifies EVT-1 and UT inspections to detect small tight cracks before component functionality is challenged.

The BWRVIP inspections are directed to component welds and weld heat affected zones, where experience has shown IGSCC cracks will initiate.

The BWRVIP-specified EVT-1 and UT examinations have superior crack detection and characterization capability as compared to the Code VT-3 examination.

The inspection of highly susceptible creviced weld locations every outage (visual EVT-1) or every other outage (UT) is superior in crack detection and inspection Page 3 of 8 Attachment 1 To Entergy Letter No. 2.08.008 (PRR-16)frequency to the VT-3 examination required every period. The sparger bracket inspection method (VT-1) is superior to the code inspection method (VT-3) and the inspection intervals are similar. The 25% sampling of non creviced welds ensure that all welds are inspected in a 10 year interval.

The BWRVIP inspection requirements for reactor vessel interior accessible areas provide an acceptable level of quality and safety as compared to the ASME Code requirements by providing an equivalent or in most cases superior inspection methods. Additional examples of components in this category are: Top Guide (BWRVIP-26-A)

Jet Pumps (BWRVIP-41, Revision 1 and BWRVIP-138)

• Control Rod Guide Tube and Fuel Support Castings (BWRVIP-47-A) 6.2 B13.20, Interior Attachments Within the Beltline (B-N-2)The ASME Code requires a VT-1 inspection of accessible reactor interior surface attachment welds each 10 year interval.The BWRVIP requires an EVT-1 inspection on the majority of attachment welds in the beltline region in the first 12 years and then 25% during each subsequent 6 years.The Jet Pump Riser Brace inspection requirements are used as an example for comparison between the ASME Code and the BWRVIP inspection requirements.

Jet Pump Riser Braces (BWRVIP-41, Revision 1 and 48-A)0 The ASME Code requires a 100% VT-1 inspection of the Jet Pump riser brace-to-reactor vessel wall pad welds each 10 year interval.The BWRVIP requires an EVT-1 inspection of all the Jet Pump Beam riser brace-to-reactor vessel wall pad welds the first 12 years and then 25% during each subsequent 6 years.The Code VT-1 examination is conducted to detect discontinuities and imperfections on the surfaces of components, including such conditions as cracks, wear, corrosion, or erosion. The BWRVIP enhanced VT-1 (EVT-1) is conducted to detect discontinuities and imperfections on the surface of components, including fatigue cracks and very tight cracks characteristic of inter-granular stress corrosion cracking (IGSCC). General wear, corrosion, or erosion, is generally not a concern for stainless steel due to its inherently tough, corrosion resistant material characteristics.

However, the process of performing an EVT-1 inspection would detect such degradation mechanisms.

The Code VT-1 visual inspection method requires that a letter character with a height of 0.044 inches can be read at a maximum distance of 2 feet. The BWRVIP EVT-1 is a visual inspection method where the equipment and environmental conditions are such that they can achieve a 1/22 mil (0.0005 inch) resolution on the inspection surface.The ASME Code and the BWRVIP have the same flaw evaluation criteria for detected indications.

Both criteria measure the observed surface indication and compare them against acceptable flaw sizes determined by ASME Section Xl Code.Page 4 of 8 Attachment 1 To Entergy Letter No. 2.08.008 (PRR-16)The BWRVIP inspection method of interior attachments within the reactor vessel beltline has superior flaw detection capability (0.0005 inches versus 0.044 inches resolution) compared to the ASME Code. The enhanced flaw detection capability of an EVT-1, with a less frequent inspection schedule and the same flaw evaluation criteria, results in the BWRVIP inspection requirement providing the same level of quality and safety to that provided by the ASME Code.6.3 B13.30 Interior Attachments Beyond the Beltline Region (B-N-2)The BWRVIP requires as a minimum the same VT-3 examination method as the Code for interior attachment welds beyond the beltline region and in some cases specifies an enhanced visual inspection technique EVT-1.As described in Attachment 2, the following components have the same VT-3 method of examination, the same scope of inspection (accessible welds), the same inspection frequency (each 10 year interval) and ASME Section XI flaw evaluation criteria: Therefore, the level of quality and safety provided by the BWRVIP requirements are equivalent to that provided by the ASME Code. Examples of component attachment welds in this category are: " Steam Dryer Holddown Brackets (BWRVIP-48-A)

• Guide Rod Brackets (BWRVIP-48-A)

• Surveillance Specimen Upper Holder Brackets (BWRVIP-48-A)

Additionally, there are interior attachment welds outside the beltline region that the BWRVIP requires an EVT-1 inspection instead of the Code required VT-3 inspection.

The inspection frequency for EVT-1 is every four refueling outages (8 years) as compared to the Code inspection frequency of 10 years. The Code VT-3 examination is conducted to detect component structural integrity by ensuring components general condition is acceptable.

An enhanced EVT-1 is conducted to detect discontinuities and imperfections on the inspection surfaces, including such conditions as tight cracks caused by IGSCC. Therefore, with the EVT-1 inspection method, the same inspection scope (accessible welds), an increased inspection frequency (8 years instead of 10 years) and the same flaw evaluation criteria (Section Xl), the level of quality and safety provided by the BWRVIP criteria is superior to that provided by the Code.The Core Spray piping bracket-to-vessel attachment weld is used as an example for comparison between the ASME Code and BWRVIP inspection requirements.

Vessel ID Attachment Weld Inspection and Flaw Evaluation (BWRVIP-48-A)

The ASME Code inspection requirement is a VT-3 examination of each weld every 10 years.The BWRVIP inspection requirement for the Core Spray piping brackets attachment weld is that each weld is inspected every four refueling outages (8 years) with an EVT-1.Page 5 of 8 Attachment 1 To Entergy Letter No. 2.08.008 (PRR-16)The BWRVIP examination method EVT-1 has superior flaw detection and sizing capability, the inspection frequency is greater than the Code requirements and the same flaw evaluation criteria is used. Therefore the BWRVIP inspection criteria will provide a superior level of quality and safety as provided by the ASME Code.6.4 B13.40 Welded Core Support Structure-Core Support Structure (B-N-2)The ASME Code requires a VT-3 of accessible surfaces each 10 year interval.The BWRVIP requires as a minimum the same inspection method VT-3 as the Code for integrally welded Core Support Structures or either an enhanced visual inspection EVT-1 or volumetric examination UT.As described in Attachment 1, the following component has the same VT-3 method of inspection, the same scope of inspection (accessible surfaces), the same inspection frequency (each 10 year interval) and the same flaw evaluation criteria, with the addition of an enhanced visual EVT-1 examination of the tie-rod locking devices. Therefore, the BWRVIP requirements provide a level of quality and safety equivalent to or superior to that provide by the ASME Code. An example of a component in this category is:* Core Shroud Repair Tie-rods (BWRVIP-76)

The BWRVIP also requires either an EVT-1 or UT of core support structures.

The core shroud is used as an example for comparison between the ASME Code and BWRVIP inspection requirements.

BWR Core Shroud Inspection and Flaw Evaluation Guideline (BWRVIP-76) 0 The Code requires a VT-3 of accessible surfaces every 10 years.* The BWRVIP requires an EVT-1 or UT of each core shroud design reliant weld every 10 years (maximum).

When the EVT-1 method is used for one-sided weld inspection due to inaccessible surfaces, the inspection interval shall be 6 years (maximum).

This BWRVIP examination methods (EVT-1 or UT) are superior to the Code required VT-3 for flaw detection and characterization.

The BWRVIP inspection frequency is equivalent to or greater than the inspection frequency required by the Code. The superior flaw detection and characterization capability, with an equivalent or greater inspection frequency and the same flaw evaluation criteria, results in the BWRVIP criteria providing a level of quality and safety equivalent to or superior to that provided by the Code requirements.

7.0 Conclusion Pursuant to 10 CFR 50.55a(a)(3)(i), using these BWRVIP guidelines as an alternative to the ASME Section Xl Code requirements provides an acceptable level of quality and safety. In many cases the BWRVIP examination requirements exceed the requirements, of ASME Xl by requiring more detailed examination criteria (for example, VT-1 and UT Page 6 of 8 Attachment 1 To Entergy Letter No. 2.08.008 (PRR-16)for shroud welds vs. VT-3). The BWRVIP Guidelines also provides detailed inspection areas and guidance for scope expansion if a defect is detected.8.0 Duration of Proposed Alternative Entergy proposes to use the alternative for the fourth Inservice Inspection Interval for Pilgrim Nuclear Power Station.9.0 Precedents Similar relief requests were approved for James A.
