() REQUEST FOR RELIEF R0001 PRESERVICE INSPECTION COMPONENT:

Pressure retaining weld in piping, code category B-J. (See attached listing).

CODE:

Pressure retaining piping welds were fabricated in accordance with ASME Section III, Class 1 i requirements. Preservice inspecticas are to be performed in accordance with ASME Section XI, 1977 Edition through and including Summer 1978 Addenda.

CODE REQUIREMENTS ASME SECTION XI:

Pressure retaining piping welds are required to be Surface (magnetic particle or liquid penetrant) and Volumetric (Ultrasonic) inspected for Pre-service Inspection On accordance with ASME Section XI, IWB-2500-1, examination category B-J, Item B9.10.

INFORMATION TO

(

) SUPPORT THE DETERMINATION THAT

~

THE CODE REQUIRE-MENT CANNOT BE MET:

Due to the configuration, there is not sufficient area to perform a meaningful Ultrasonic examination.

REASON WHY RELIEF SHOULD BE GRANTED:

1) Weld has been Volumetrically examined by Radiography and hydrostatically tested, found acceptable in accordance with ASME Section III, Class 1 requirements
2) Weld has been Surface examined by Magnetic m Particle, found acceptable in accordance with ASME Section XI, Class 1 requirements.

Low Pressure Core Spray (CSL) 1E21 FC001 High Pressure Core Spray (CSH) 1E22 PC001 RHS "B" 1E12 PC002-A Bolting Arrangement (TVP) 1E22 PC001 CODE: CSL, CSH and the RHS "B" pumps were designed and l

f abricated to the ASME Section III, Class 2 requirements. Applicalbe Preservice Inspection to be performed in accordance with the ASME Section XI, 1977 Edition through and including Summer 1978 Addenda.

CODE REQUIREMENT ASME SECTION XI: The pressure retaining welds located on the CSL, CSH, and RHS "BY pumps are required to be Preservice surface examined (magnetic particle) for Preservice Inspection in accordance with the ASME Section XI, IWC-2500-1 category C-G.

INFORMATION TO

[A SUPPORT THE DETERMINATION THAT THE CODE REQUIRE-MENT CANNOT BE MET:

Due to inaccessibility there is no access to the pump casing welds. Welds are located in the pump housing, flange to pump housing behind m W

bolting, and encased in concrete.. Examination of required welds would require complete disassembly of pump. If pump is disassembled for normal maintenance examination of welds will be considered at that time.

REASON WHY RELIEF SHOULD BE GRANTED:

Request for an exemption from Preservice Inspection of inaccessible portions of pump casing welds on CSH, CSL and RHS "B" pumps located inside of concrete pump support encasements. Examination of the inaccessible pump casing welds will be performed.

1) These welds have been volumetrically examined by Radiography and hydrostatically tested, i l

passed in accordance with the ASME Section III, Class 2 requirements.

2) The failure of these welds, thus leading to failure of the pump, would have no adverse affect on plant safety as redundant ECCS

CODE:

'Ihese portions of the CRD and In-Cbre housings were designed and fabricated to the ASME Section III, Class 1 requiranents. Applicable Preservice Inspections to be performed in accordance with the ASME Section XI, 1977 Edition through and including Sumer 1978 Addenda.

03E REQUIRDfENT ASME SECTICN XI: 1. Peripheral Control Rod Drive Housings welds are required to be Surface Examined (Dye Penetrant) for Preservice Inspection in accordance with ASME Section XI, IWB-2500-1,  !

examination category B-0.

2. Pressure retaining bolting for the Flange to 1 J

- Flange joints, located on the CRD and Incore Housings, are required to be visually ,

examined (VT-1) for Preservice Inspection in i accordance with ASME Section XI, IWB-2500-1, examination category B-G-2.

INMRMATION 'IO SUPPORT 'IHE DETTERMINATICN 'IHAT

The weld area's and bolting are not accassible for inspection unless the Control Rod Drive

, A total (CRg) 360 Surfacesupport Examination structure cannot is be removed.

accurately accmplished frm the outside, due to interference frm adjacent CRD Housing.

Inspection of the weld frm the inside of the i l

CRD Housing would require that the control Rod Drive mechanism be removed, which could result in danage to the Drive.

REASCN WHY RELIEF SHOUID BE GRMTTED: Request for exerption from Preservice Inspection of the Peripheral CRD Housing welds (Tube to Tube to Flange), eight (8) bolts associated with each Flange of 145 CRD Housings and four (4) bolts associated with each Flange of 45 Incore Housings, be granted for the following reasons:

Visual Examination (VF-1) of the internals, of subject pmp and valve, would require disassembly of the c.uwent. The disassenbly of these pmps would also impose an undue burden on the plant and may increase the probability of I

Should the pmps or valves be required to be disassernbled for other plant reasons, the required Preservice Visual Examinations will be considered.

Rev. 01 06/25/85 REQUEST FOR RELIEF R0003 P,RESERVICE INSPECTION f'~x b

COMPONENT: Pump casing welds inaccessible, due to concrete and pump housing encasement for the following pumps:

Pump Pump No.

Low Pressure Core Spray (CSL) 1E21 PC001 High Pressure Core Spray (CSH) 1E22 PC001 RHS "B" 1E12 PC002-A Bolting Arrangement (TVP) 1E22 PC001 CODE: CSL, CSH and the RHS "B" pumps were designed and fabricated to the ASME Section III, Class 2 requirements. Applicalbe Preservice Inspection to be performed in accordance with the ASME Section XI, 1977 Edition through and including Summer 1978 Addenda.

CODE REQUIREMENT ASME SECTION XI: The pressure retaining welds located on the CSL, CSH, and RHS "BY pumps are required to be Preservice surface examined (magnetic particle) for Preservice Inspection in accordance with the ASME Section XI, IWC-2500-1 category C-G.

INFORMATION TO SUPPORT THE

(h x DETERMINATION THAT THE CODE REQUIRE-MENT CANNOT BE MET:

Due to inaccessibility there is no access to the pump casing welds. Welds are located in the pump housing, flange to pump housing behind bolting, and encased in concrete. Examination of ,

required welds would require complete disassembly of pump. If pump is disassembled for normal maintenance examination of welds will be considered at that time.

REASON WHY RELIEF SHOULD BE GRANTED: Request for an exemption from Preservice Inspection of inaccessible portions of pump casing welds on CSH, CSL and RHS "B" pumps located inside of concrete pump support encasements. Examination of the inaccessible pump casing welds will be performed.

1) These welds have been volumetrically examined by Radiography and hydrostatically tested, passed in accordance with the ASME Section III, Class 2 requirements.
2) The failure of these welds, thus leading to failure of the pump, would have no adverse affect on plant safety as redundant ECCS systems are provided.
