1.8 CLASSIFICATION OF COMPONENTS-i i

Components have been classified for purposes of inservice inspection in accordance with the requirements of 10CFR50, the guidance contained in Regulatory Guide 1.26, Rev. 3, and commitments made in the Final Safety Analysis Report (FSAR).

A series of special drawings titled "ASME Section XI Boundary P&ID" and identified as ISI-M-XX (where XX corresponds to the construction P&ID number) have been color coded to define the boundaries of the ASME Code Class 1, 2& 3 piping systems.

These ASME Code Classes are assigned to Quality Group A, B and C systems or portions of systems as required per ASME Section XI IWA-1320, IWA-1400, and 10CFR50. These boundaries (as e xplained i in ISI Note A on the P&ID's) identify the areas where the require-ments of ASME Section XI apply in their entirety (including !

repairs & replacements) as described in this program.

The use of color coding and notes on the ASME Section XI Boundary P&ID's is to assure that all interfaces with the Authorized '

Nuclear Inservice Inspector are identified.

These ASME Section XI Boundary P&ID's are included in Appendi x A.

) 1.9 REPAIRS AND REPLACEMENTS ASME Section XI repairs and replacements will be performed when all the requirements of the code applicable to construction of a particular component have been met. Repairs and replace-ments that meet ASME Section XI requirements are defined in Specification 8031-G-33.

(_I (2) Surfdce examinations of RPV components shall be performed in accordance with Section XI, IWA-?220 and Section V,.

Article 6 for liquid penetrant examinations or Section V, Article 7 for magnetic particle examinations. (See l/hg y Footnote 4)

(3) Volumetric examinations of the RPV welds (excluding the nozzle to safe-end and safe-end to extension and/or pipe l welds) shall be performed by ultrasonic rethods in accor- i dance with Section XI, IWA-2230 and Section V, Article 4. l i

Verification of instrument calibration per T-431 shall be performed at the beginning and end of the RPV preservice inspections. (See Footnotes 1, 4) {

l (4) Volumetric examination of the RPV nozzle to safe-end and z safe-end to extension and/or pipe welds shall be per- j formed by ultrasonic methods in accordance with Section i XI, IWA-2230 and Section V, Article 5. In addition to f the requirements of Article 5, weld reflectors producing )

a response greater than 20% of the reference level shall i l

be recorded. Weld reflectors producing a responce equal to or greater than 50% of reference level shall be !

recorded and investigated to determine the shape, identity and location and shall be sized to end points producing a

'N response equal to both 50% and 20% of reference level.

.(J

\ Weld reflectors producing a response greater than 50%

reference level shall be characterized in accordance I with IWA-3000 and evaluated in terms of the appropriate acceptance standard. The calibration standard shall be fabricated from material of the same material specification, product form and heat treatment as one of the materials being examined.

Any indication detected in the weld and required volume not readily attributable to geometrical or metallurgical conditions will be recorded regard 3ess of ultrasonic amplitude response and investigated by a Level II or Level III examiner to the extent necessary to determine the shape, identity, and location of the reflector. PECo will disposition and take the appropriate corrective action for ;

any indication investigated and evaluated'to be other than :

geometrical or metallurgical in nature.

For indications determined to be related and intermittent, i.e. geometrical or metallurgical in nature, the shape, ;

identity, and location of the reflector will only be i '

recorded for the peak amplitude response of the related family of indications.

'( corresponding with the Code classification of the component being repaired.

(3) The acceptance criteria for initial service of replacement Where components shall be in accordance with IWB-3110.

applicable, references in IWB-3110 to the criteria and standards of ASME Section III, Article NB, shall refer to the criteria and standards of the Design Specification Code Classification of the replacement component. (See !

1 Footnote 3) ;

2.2.4.1 FLAW INDICATION CHARACTERI2ATION Flaw indications detected during preservice examinations or during baseline examination of replacement components shall meet the criteria and standards required by the Design Specification prior to characterization per IWB-3400.

(1) Flaw indications detected during preservice examinations of repairs shall be characterized in accordance with IUB-3420 ;

and compared with the acceptance standards specified in I IWB-3410.

2.2.4.2 ACCEPTANCE STANDARDS IN PREPARATION Should an acceptance standard specified in IWB-3410 be in the

() course of preparation, flaw indications that exceed the acceptance standards of the Design Specification shall be evaluated to determine an appropriate disposition.

2.5 INSPECTION PROGRAM FOR ASME CODE CLASS 1 PIPING

'2.5.1 EXAMINATION SCHEDULE The Preservice Inspection examinations for Class 1 piping shall be completed prior to initial plant startup.

~

A detailed exami-nation schedule is included in the Examination Plan referenced in Section 2.6.

2.5.2 EXAMINATION CATEGORIES AND REQUIREMENTS Preservice inspection of Class 1 pipe components shall, to the extent practical within the limitations of design, geometry, and materials of construction, meet the requirements of the ASME Section XI Edition and Addenda specified in Section 1.4. !

Table 2.0-3 identifies the Class 1 pipe components subject to preservice inspection. This table provides the corresponding Section XI, Table IWB-2500-1 item number, examination category, the required method of examination, acceptance standard for evaluation, and the extent of examination.

Pursuant to 10CFR50.55a(g), should an ASME Code or Augmented

~

requirement be determined to be impractical, a relief request j shall be prepared in accordance with Section 1.2 using the

( method prescribed in FSAR 0250.5, Appendix A, and shall be referenced in Table 2.0-3. Conditions limiting compliance with PECo special requirements as identified in this program and the applicable examination plan shall not constitute grounds for a relief request. Accordingly, these conditions need only be documented on the applicable Examination Report.

2. 5. 3 - EXAMINATION TECHNIQUES AND PROCEDURES The techniques and procedures for visual, surface and volumetric examinations shall meet the requirements of Section XI, IWA-2200 ;

as described below. Examinations, conducted in accordance with ASME Section V, shall use the 1980 Edition with the Addenda through Winter 1981. The examination techniques included in later editions and addenda may be used as an alternative.

, Nondestructive examinations shall be performed using a written procedure. Requirements for written procedures are determined by the referenced Code section. Appropriate details and requirements may be included in a number of documents like the Examination and Testing Plans referenced in Section 1.3 and/or specific procedures. i (1) Visual examinations of Class 1 pipe components shall be performed in accordance with Section XI, IWA-2210

() and Section V, Article 9. (See Footnote 3) 1 P-334/3(p29) 2-16 Rev. O, 8/87 {

i

Specification 8031-P-504

/~)' (2) Surface examinations of Class 1 pipe components shall be performed in accordance with Section XI, IWA-2220 i

and Section V, Article 6 for Liquid Penetrant Examina- l^/I\

I tions or Section V, Article 7, for magnetic particle examinations. (See Footnotes 3,5)

(3) Volumetric examinations of Class 1 pipe components, by ultrasonic methods, shall be in accordance with Section XI, IWA-2230 and Appendix III including Supplement 7 for welds in austenitic materials. In addition to the requirements of IWA-2230 and Appendix III, weld reflectors producing a response equal to or greater than 50% of

! reference level, and indications suspected to be a crack, lack of fusion or incomplete penetration regardless of amplitude, shall be recorded. Recorded indications shall be investigated te the excunt necessary to determine the shape, identity and location of the reflector.

Any indication detected in the weld and required volume not readily attributable to geometrical or metallurgical conditions will be recorded regardless of ultrasonic amplitude response and investigated by a Level II or Level III examiner to the extent necessary to determine the shape, identity, and location of the reflector.

PECo will disposition and take the appropriate corrective

action for any indication investigated and evaluated to

.() be other than geometrical or metallurgical in nature. i l

For indications determined to be related and inter-mittent, i.e. geometrical or metallurgical in nature, the shape, identity, and location of the reflector will only be recorded for the peak amplitude response of the related family of indications.

At PECo's option and to the extent practical, the exami-nation volume for Class 1 pipe welds will be expanded to include essentially the full wall thickness of the pipe. {

Examination volume of austenitic, nickel alloy and dis- 1 similar metal pipe welds will be further extended to a {

vertical line drawn one-half inch from the fusion line j at each toe of the weld. ]

i (See Footnotes 1,3,6, and Note 2 of Table 2.0-3)

(4) When radiography is used, the examinations shall be performed in accordance with Section V, Article 2.

(See Footnotes 3,4)

(5) Alternative examination methods, including combinations of visual, surface and/or volumetric methods, or newly developed techniques may be substituted for the above specified methods, provided the Inspector is satisfied

(]) that the results are demonstrated to be equivalent or superior to those of the specified method. l l

2.12 EXAMINATION PLAN FOR ASME CODE CLASS 1 VALVES The Examination Plan, titled " Limerick Generating Station Unit !

2 Preservice Inspection Examination Plan for Nuclear Piping Systems", document number 8031-P-505 specifies the details as to how the ASME Section XI Code and augmented requirements are to be met. Included in the scope of the document are the details relating to component identification, location, procedures, calibration blocks, special equipment, and other items necessary to perform the examination of ASME Code Class 1 valves.

Components that are subject to augmented inspection require-ments are identified by the addition of a "(+)" symbol to the applicable ASME Code Category.

2.13 REQUEST FOR RELIEF FROM ASME SECTION XI REQUIREMENTS -

CLASS 1 VALVES 2.13.1 RELIEF REQUEST ASME Class 1 Valves exceeding 4" NPS.

2.13.1.1 REQUIREMENT FROM WHICH RELIEF IS REQUESTED

}

ASME Section XI, Table IWB-2500-1, Category B-M-2, Item B12.50, requires VT-3 examination of the internal pressure boundary surfaces of one valve in each group of valves of the same design, manufacturing method, manufacturer, and function. The examinations are to be performed once prior to initial plant start-up. Relief is requested from performing the preservice VT-3 visual examinations for valves not requiring disassembly during plant construction.

2.13.1.2 JUSTIFICATION For those valves requiring disassembly during construction, the VT-3 visual examinations will be performed as required.

l'/I\ "

i For those valves not requiring dicacccmbly during construction, it is intended that the examinations performed by the manu-facturer and the field inspections performed prior to instal-lation serve as an acceptable alternative to the Section XI )

preservice examination.

' Edition of Section XI of the ASME Code in 10CFR50.55a. However, one of the changes affected by the Rule in 48 FR 5532 states, in part, "The regulation does not currently address the inservice-ir.spection of containments. Since this amendment is only intended to update current regulatory rc~uirements to include latest Code Addenda, the requirements of Subsection IWE are not imposed upon Commission licensees by this amendment."

10CFn50.55a presently only incorporates those portions of Section XI that address 'he ISI requirements for ASME Code Class 1, 2, and 3 components and their supports.

Since the preservice inspection program will be performed in accordance with the 1980 Edition through Winter 1981 Addenda of Section XI of the ASME Code, the requirements of Subsection IWE for containment-related examinations are not applicable to

_.[' 'N Limerick Unit 2.

The pressure and structural integrity of the primary containment shall be determined by examination and testing in accordance with Section 3/4.6 of the Limerick Technical Specifications. Piping

- associated with isolation valves at the primary containment penetrations shall be examined in accordance with the applicable AS!;E Code Class 1 or 2 Inspection Program as described in this document.

Class MC component welds between penetrations and liner plate, access hatches and liner plate and pressur-e retaining welds not backed by concrete (e.g., flued head to penetration sleeve welds) shall be examined and maintained in accordance with the Codes ar.d Standards referenced in the Final Safety Analysis Report, Section 3.8.2 and this section.

5.1.1 TESTS FOLLOWING REPAIR, MODIFICATION, OR REPLACEt1ENT 5.1.1.1 LEAKAGE TEST Except as noted in 5.3.1.2, repairs, modifications, and replacements of Class 1, 2, and MC components that are part of the primary containment pressure retaining boundary shall

(~) be subjected to a pneumatic leakage test in accordance with i/ the provisions of Title 10, Part 50, of the Code of Federal Regulations, Appendix J, Paragraph IV.A, which states:

The measured leakage from this test shall be included in the report to the Commission !

required by the V.A. The acceptance criteria of III.A.5(b),

III.B.3, or III.C.3, as appropriate, shall be met. Minor modifications, replacements, or resealing of seal-welded doors performed directly prior to the conduct of a scheduled Type A test do not require a separate test."

5 1.1.2 DEFERRAL OF LEAKAGE TESTS Leakage test for the following minor repairs or modifications to the pressure retaining boundary may be deferred until the next scheduled leakage test provided the applicable non-destructive examinations are performed.

(a) welds of attachments to the surface of the pressure retaining boundary,

~6.3 EXAMINATION PLAN FOR ASME CODE CLASS 1, 2& 3 COMPONENT SUPPORTS (EXCEPT RPV)

The Examination Plan titled'" Limerick Generating ~ Station Unit Preservice Inspection Examination Plan for Nuclear Piping Systems", document number 8031-P-505, specifies the details as to how the ASME <Section XI- requirements are to. be met f or ASME Code Class.1, 2 and 3, component supports. Included in examination plan are isometric = drawings providing the support locations and the details relating to component identification, location, procedures, calibration blocks, special equipment and other items necessary to perform the examination and testing of ASME Code Class 1, 2 and-3 component supports.

Components that are subject to augmented inspection require-ments are identified by the addition of a "(+)" symbol to the applicable ASME Code Category.

6.4 REQUEST FOR RELIEF FROM ASME SECTION XI REQUIREMENTS -

. CLASS 1, 2& 3 COMPONENT GUPPORTS 6.4.1 RELIEF REQUEST Class 1, 2& 3 (Quality Group A, B & C) Component Supports 6.4.1.1 REQUIREMENT FROM WHICH RELIEF IS REQUESTED ASME Section XI, IWF-2200(b) requires the preservice inspection VT-3 and VT-4 visual examinations of selected Code Class 1, 2

& 3 component supports be performed completely, once, f ollowing the initiation of hot functional tests.

Relief is requested from the requirement for performance of the preservice VT-3 examinations of all supports and the VT-4 /I\

examinations of spring supports after the initiation of hot functional testing. The VT-4 of snubbers shall, however, be ,

performed as required, following the initiation of the hot l / A, functional tests.

6.4.1.2 JUSTIFICATION The Limerick Unit 2 preservice visual examinations are being performed in conjunction with the Construction Quality Assurance f Program using examination personnel who are fully qualified under A ASME Section XI rules. Included are 100% of the ASME Code ;

Class-1, 2& 3 (Quality Group A,B&C) component supports in systems or portions of systems not exempted by Section XI IWB, IWC and IWD. (Note: appropriate IWE components are examined in accordance with the requirements of IWB and IWC as applicable)

%)

To implement a program of this magnitude following the initiat-ion of hot functional tests would require the installation /

removal of large amounts of scaffolding and insulation as well as the disassembly / assembly of surrounding components solely for the purpose of providing access to perform the required visual examinations. This would involve an unnecessarily high l/h\

risk of damage to surrounding components and an impact on the Plant start-up testing program.

The condition of the component supports after hot functional testing will be evaluated by the implementation of a testing program during A preoperational and start-up testing as described below in Section /'\

6.4.1.3.

6.4.1.3 ALTERNATE TO SECTION XI REQUIREMENTS The preservice visual examinations are to be perf ormed as an l/h\

integral part of the plant construction, as-built reconciliation, preoperational and start-up testing activities.

The preservice examination of component supports shall include the jh following:

?3 (1) A VT-3 visual examination shall be perfccmed on 100% of the

(_/ applicable supports to determine general meccanical and structural conditions, such as the presence of loose parts, debris, or abnormal corrosion products, wear, erosion, corrosion and the loss of integrit;r at bolted or welded connections. The VT-3 visual examination may require, as applicable to determine structural integrity, the measure-ment of clearances, detection of physical displacements, structural adequacy of supporting elements, connection between load carrying structural members and tightness of bolting.

(2) A VT-4 visual examination shall be performed on 100% of the applicable spring and constant load type supports and mecha-nical snubbers to determine conditions relating to the operability of the support. The VT-4 visual examination shall confirm functional adequacy, verification of settings, and/or f reedom of motion and may require disassembly of the support and operability test. Snubbers shall be dis-assembled and tested in accordance with Limerick Technical A

/'\

Specification requirements.

In addition to the required visual examinations, each piping system shall be " walked down" by piping stress engineers as part of the as-built reconciliation program. These engineers

() will perform a visual review of the system to determine that all support clearances, physical displacements and freedoms l/)\

of motion are as designed and will permit the proper free ll\

thermal and seismic movement of the system. All deviations which would either compromise piping system performance as designed or prevent the proper free movement shall be documented and corrected including the performance of'new preservice baseline visual examinations as required.

During preoperational and start-up testing, a dynamic testing program will be implemented in accordance with Limerick FSAR Table 3.9-7 to verify that the piping system responds, under design conditions, in an acceptable manner as predicted by analysis. Included in this program are:

A. Hot Deflection Testing B.

C.

Transient Vibration Testing Steady State Vibration Testing

Valves identified in Items 1, 2 and 3 above are exempt f rom the 7g t ,/ requirements of ASME Section XI Subsection 'WV but may require NDE per ASME Section XI Subsection IWB, IWC and IWD, depending on the applicable Quality Group classification.

Category A valves that perform a containment isolation funct-ion will be tested to meet the criteria of Appendix J to 10CFR50. Category A valves which perform a pressure isolation function will be tested to meet the requirements of ASME Section XI, IWV-3420.

8.3 TESTING PLAN FOR SAFETY-RELATED VALVES The Testing Plan, titled " Limerick Generating Station, Unit 2 Section XI Testing Plan for Safety-Related Pumps and Valves' document number 8031-P-507, specifies the details as to how the ASME Section XI requirements are to be met. Included in the scope of this document is a list of the valtes to be tested, the ASME Section XI category, test frequency, type of test and any relief request from Section XI requirements. This document will be utilized for the performance of the Limerick Unit 2 preservice testing and continually updated for subsequent inservice testing.

Specification 8031-P-504 gs 8.4 REPAIRS AND REPLACEMENTS ASME Section XI, IWV-3417 requires corrective action if the measured stroke time for a valve which normally strokes in ten seconds or less varies by fifty percent from the last measured time. ASME Section XI, INV-3413 allows measurement to the nearest second for stroke times of ten seconds or less. For rapid actuating solenoid and air operated valves with stroke times of five seconds or less, the application of the above criteria could result in requiring corrective action when the valves are functioning norms 11y. To preclude this, the follow-ing criteria will be used for valves with normal stroke times of five seconds or less. If the stroke time is determined to be less than five seconds the valve will be considered operable without comparing stroke time with previous test results. If the time exceeds five seconds corrective action will be taken.

For valves with stroke times greater than five seconds the requirements of ASME Section XI, INV-3417 and IWV-3413 will apply.

O 9.0 AUGMENTED PRESERVICE INSPECTIONS This section defines the Limerick Generating Station Unit 2 preservice inspection requirements, which are beyond those required by Section XI of the ASME Boiler and Pressure Vessel Code and augments the Preservice Inspection, as part of the Philadelphia Electric Company's (PECo) licensing ' 7mitments.

< 9.1 . AUGMENTED REQUIREMENTS - REACTOR PRESL: .E VESSEL (RPV)

The following are the augmented preservice inspections applicable to Limerick Generating Station Unit 2 RPV. The examination method, frequency and coverage are specified in " Philadelphia Electric Company Limerick Generating Station Unit 2 Reactor Pressure Vessel Examination Plan for Preservice Inspection, PIP-2 document number 8031-M-246B-LATER , hereafter referred to as the Examination Plan for the RPV.

9.1.1 REGULATORY GUIDE 1.150, REVISION 1, FEBRUARY 1983, WITH APPENDIX A, ALTERNATE METHOD. " ULTRASONIC TESTING OF REACTOR VESSEL WELDS DURING PRESERVICE AND INSERVICE EXAMINATIONS"

) ASME Section XI preservice ultrasonic examinations of Unit 2 RPV Category B-A and B-D welds will be performed in accordance with Reg. Guide 1.150, Alternate Method, which outlines acceptable methods for remote automatic and manual ultrasonic equipment certification and calibration, recording and sizing of indications and reporting of examination results.

9.1.2 NUREG_0619, NOVEMBER 1980, "BWR FEEDWATER NOZZLE AND CONTROL ROD DRIVE RETURN LINE NOZZLE CRACKING, RESOLUTION OF GENERIC TECHNICAL ACTIVITY A-10."

Preservice inspections of the RPV Feedwater Nozzles will include the examinations specified in NUREG 0619, Section 4.3 for the Triple-sleeve Sparger design. The Control Rod Drive (CRD)

Return Line Nozzles are not used at Limerick. The preservice inspection of the capped CRD nozzle will include a final liquid penetrant examination of the inside nozzle blend radius and bore regions and the reactor vessel wall area beneath the nozzle.

Thereaf ter, the capped CRD nozzles will be examined in accordance with ASME Section XI only.

9.2 AUGMENTED REQUIREMENTS - NUCLEAR PIPING SYSTEMS The following are the augmented preservice inspections appli-cable to Limerick Generating Station Unit 2 nuclear piping systems. .The examination method and coverage are specified in " Limerick Generating Station Unit 2 Preservice Inspection Examination Plan", document number 8031-P-505 hereafter referred to as the Examination Plan for Piping.

9.2.1 HIGH ENERGY PIPING BETWEEN CONTAINMENT ISOLATION VALVES AND FIRST OUTBOARD RESTRAINT FOR WHICH NO BREAKS ARE POSTULATED (REFERRED TO AS "NO BREAK" BOUNDARIES IN THIS PROGRAM)

NRC Mechanical Engineering Branch (MEB) Technical Position MEB 3-1 (NUREG 0800) prescribes that cracks or breaks need not be postulated for containment isolation piping provided that certain

- stress criteria are met and all pipe welds are volumetrically examined during each inservice inspection interval. The Limerick Generating Station FSAR Section 3.6.2.1 commits PEco to performing these examinations for all "no break" piping welds. The augmented inservice inspection will provide 100%

volumetric examination of circumferential and longitudinal pipe

~

welds within the "no break" boundaries. These examinations will

\ be performed in accordance with the requirements of ASME Section XI with the exception that the weld and required volume shall be extended to include essentially 100% of the through wall thickness.

The "no break" boundaries are as summarized in Table 1 below.
