PRE-SERVICE INSPECTION RELIEF REQUEST ffl I. IDENTIFICATION OF COMPONENTS:

All components in Class 1 and Class 2 piping systems requiring ultrasonic examination as the method of examination.

II. CODE RE UIREMENT:

The preservice inspection program for Susquehanna Nl was prepared in accordance with Section XI of the ASME Boiler and Pressure Vessel. Code, 1974 Edition to the Summer 1975. This Edition and Addenda does not specifically address volumetric examination of welds in piping systems but references the. pro-visions of Article 5 of ASME Section V.

III. BASIS FOR RELIEF:

Relief is requested from utilizing the provisions of ASME Section V, Article 5, from the referencing cod'e edition and addenda;in lieu of this requirement, PP6L proposes to use Appendix III, "Ultrasonic Examination Method for Class 1 and 2 plplng systems made from Ferritic Steels" from the Winter 1975 Addenda.

Rev. 0 5/15/81

IV. JUSTIFICATION:

Appendix III, 1977 Edition to the Summer 1978 Addenda has been accepted for use by incorporation of this edition and addenda into 10 CFR 50.55a. Appendix III, Winter 1975 Addenda closely parallels the later Code except that. the required examina-tion volume is more conservative in the Winter '75 Addenda (i.e.,

Figure IWB-3514.1(a) of Winter '75 versus Figure IWB-2500-8 of the 1977 Edition) .

V. ALTERNATE PROVISIONS:

Appendix III of ASME Winter 1975 Addenda will be used for piping system ultrasonic examination.

Rev. 0 5/15/81

RELIEF RE UEST ¹2 I. IDENTIFICATION OF COMPONENTS:

All Class 1 and Class 2 bolting in piping, pumps, and valves.

II- CODE RE UIREMENTS:

C1.4, C2.4, CD Pressure retaining bolting Visual and C3.2, C4.2 exceeding 1 inch either surface or volumetric These exam'inations must be performed completely as a preservice examination requirement prior to initial plant start-up.

Rev. 0 5/15/81

0 III. BASIS FOR RELIEF:

PP&L requests relief from the examination requirements of ASME Section XI 1974 Edition to Summer 1975 Addenda; examinations shall be performed in accordance with the more current requirements of ASME Section XI 1977 Edition to Summer 1978 Addenda as follows:

• Nuts, bushings, washers, threads, in base material and flange ligaments between threaded stud holes.

Rev. 0 5/15/81

IV. JUSTIFICATION:

The justification for upgrading the 1977 Edition to Summer 1978 Addenda of ASME Section XI for piping system bolting examination, in lieu of the governing code edition and addenda, is to make the Class 2 requirements more closely parallel Class 1 requirements. It impractical to inspect Class 2 components more stringently than is Class 1 components and presents no adverse affect on the integrity of the component or. upon overall plant safety.

V. ALTERNATE 'PROVIS'IONS:

The requirements of ASME Section XI 1977 Edition to the Summer 1978 Addenda will be used.

Rev. 0 5/15/81

REL'IEF RE UEST 03 I. IDENTIFICATjON OF COMPONENTS:

All Class 1 and, Class 2 integrally welded support members for piping, pumps, and valves.

II. CODE RE UIREMENT:

Category B-K-1 of ASME Section XI, 1974 Edition to Summer 1975 requires volumetric examination of welds to the pressure-retaining boundary and the base metal beneath the weld zone and along the support attachment member for a distance of two support thicknesses.

Category C-E-1 of ASME Section XI, 1974 Edition to Summer 1975, requires surface examination of welds to the pressure-retaining boundary and the base metal beneath the weld zone and along the support attachment member for a distance of two support thicknesses.

ITEM EXAMINATION COMPONENT METHOD TEST NUMBER CATEGORY REQUIREMENTS B4.9, B6.5 B-K-1 Integrally welded . Volumetric Table support attachments or Surface* IWB-2500-1 C3.10, C3.40, Integrally welded Surface**. Table C3.70, C-E-1 support attachments 'XWC-2500-1 C3.100

• See Figures IWB-2500-13, 14, 15.

• • See Figure: IWC-2520-5.

Rev. 0 5/15/Sl

IV. JUSTIFICATION:

The justification for requesting relief from the governing ASME Code Edition and Addenda and upgrading to the requirements of ASME Section XI 1977 Edition to Summer l978 are as follows:

1) The weld geometries involved make a meaningful ultrasonic examination, with full coverage of the weld and required volume, questionable.

2) Surface examination of the weld and required surrounding base material is a more reliable, and sensitive examination for detecting defects in these welds.

3) Upgrading makesSection XI examination requirements more consistent with Section III construction requirements and therefore, eliminates additional surface preparation and conflict between the Codes.

Rev. 0 5/15/81

V. ALTERNATE PROVISIONS:

ASME SECTION III EXAMINATION SAFETY IMPACT RT Leak detection systems detect weld leakage, resulting in either manual or automatic isolation of the leak. These lines are not required for normal safe shutdown, alternate safe shutdown methods are available.

RT RT RT RT During normal plant power operation, weld is under approximately 20 feet of hydrostatic head.Quring normal system operation weld is under a maximum pressure of 345psig.

Leak detection systems can detect leakage during plant power or normal system operation.

Weld can be isolated and alternate cooldown paths are available using redundant RHR loop or main condenser.

RT and PT Reactor coolant pressure boundary leak detection system detect weld leakage plant technical specifications require plant shutdown with unidentified leakage greater than 5 gpm.

RT and PT RT During normal plant operation, weld is not pressurized. During normal system operation (maximum l65 psig), leakage is detected by leak detection systems. Alternate shutdown cooling path is unaffected and condenser is also available for cooldown.

RT Leak detection system detects significant leakage; containment isolation valves (2) perform weld isolation function. HPCI performs back-up function for RPV water addition for safe shutdown.

RT During normal plant power operation, welds are not under pressure. During normal system operation, significant leakage is detectable by leak detection system. Plant can be safely cooled down by unaffected RHR loop or main condenser.

RT Rev. 2 1/29/82

A SECTION III EXAMINATION SAFETY IMPACT RT and PT Reactor coolant pressure boundary leak detection system detect leakage. Plant technical specification require plant shutdown with leakage greater than 5 gpm.

Rev. 2 1/29/82

IV. JUSTIFICATION:

The justification for requesting relief from ASME Section XI examination requirements is as follows:

1) The structural integrity of. the piping pressure boundary is not in question. All the affected, Class 1 and 2 welds were subject to examination and testing requirements of ASME Section III.

2) Welds of similar configuration, welding technique, etc., in the same run of pipe, subject to similar operating pressures and temperatures are accessible for examination and, as such, provide adequate verification, by sampling, of the piping pressure boundary.

3) Visual examination of the weld during system pressure testing will be performed to detect for evidence of leakage.

4) Overall level of Plant Quality and safety is not affected by incomplete examination of welds.

Rev. 0 5/15/81

V. ALTERNATE PROVISIONS:

A supplemental surface examination of the Class 2 welds will be performed for preservice examination; Class 1 welds have received surface examination to satisfy ASME Section at this time is unnecessary. IlI'etesting Based on the most current accepted Edition and Addenda of ASME Section XI ('77 Edition to Summer '78), a surface examination of the welds will be required during subsequent inservice inspections, and will be more meaningful at that time.

IV. JUSTIFICATION:

The justification for requesting relief from ASME Section XI examination requirements is as follows:

l) The structural integrity of the welds is not in question.

These Class 2 welds were subject to examination and testing requirements of ASME Section III.

2) Relief from examination of these welds do not affect overall. plant. quality. or safety.

Welds are inaccessible to all methods of NDE.

Rev. 0 5/15/81

V. ALTERNATE PROVISIONS:

The structural integrity of all Class 1 welds covered has been rified by satisfactory completion of all ASME Section III examination. Supplemental examination, such as a surface examination performed at this time is redundant and would not result in increas-ing levels of plnat quality or safety.

Based on the most current accepted Edition and Addenda of ASME Section XI (.'77 Edition to Summer '78), a surface examination of the welds will be required during inservice inspections, and will be more meaningful at that time.

Class 2 piping welds will receive a supplemental surface examintion.

Nelds requiring relief from examination requirements due to geometric configuration were evaluated for radiographic examina-tion with specific attention to feasibility during, an inservice examination. In most cases, current state-of-the-art prohibited this method due to configuration and environment. New or improved examination techniques may improve inspectability volumetrically during future inspection. intervals; these techniques will be evaluated for. applicability,to.SSES ¹l,and implemented as required.
