1.0 SCOPE This specification covers the requirements for the design, fabrication, assembly, testing, cleaning, packaging and delivery of Mechanical Norzle Seal Assemblies (MNSA) to be used to prevent leakage from the RTD nozzles on the hot leg j
piping, the sampling nozzles on the hot leg and the pressure instrument nozzles on l
the hot leg.
1 1.1 DEFINITION OF NOMENCLATURE 1.1.1 Purchaser - ABB Combustion Engineering Nuclear Power (ABB CENP),
Windsor, Connecticut shall hereafter be referred to in this specification as the Purchaser.
1.1.2 Supplier - ABB CENP Subvendors or ABB CENP (for some activities) shall j hereafter be referred to in this specification as the Supplier. The Supplier shall be )
responsible for the fabrication, testing, cleaning, packaging, shipment and delivery' as applicable.
i 1.1.3 Subvendor Provider of goods or services, approved by ABB CENP, in accordance with its Quality Control Program, Reference 3.1.1. 4 1.1.4 The Owner - Entergy Operations, Inc.

C-NOME-SP-0067 Rev.02 Page 4 of 17 l
1.2 - DESCRIFI1ON OF THE RTD NOZZLE SEAL ASSEMBLY 1.2.1 Description of the Mechanical Nozzle Seal Assembly - The Mechanical Nozzle Seal Assembly (MNSA) is a mechanical device with a seal that encapsulates the nozzle on the locations listed below, to prevent leakage in the event of cracks in J
the nozzle welds or heat affected zones due to PWSCC of the Inconel 600 nozzle / weld material. It also acts as a restraint to prevent a nozzle from ejecting in the event of a failure of the internal nozzle to hot leg pipe weld or weld heat
)
affected zone.
a) RCS hot leg temperature nozzle b) RCS hot leg sampling nozzle c) RCS hot leg pressure instrument nozzle 1.3 STATEMENT OF ASME CODE AND SAFETY CLASSIFICATION I.3.I- The MNSA hardware is designed and fabricated to the ASME Code,Section III (Reference 3.2), Subsection NB requirements. Since the hardware is machined from bar stock and bolting material, with no welding involved, the MNSA retaining hardware is supplied as material and will not be "N" stamped or hydrostatically tested. After the hardware is installed, a visual inspection for leakage will be performed as part of plant restart. m test will be conducted at ,
normal operating pressure and with the test temperature determined in accordance with the Waterford 3 Technical Specifications. I 1.3.2 In consideration of the present ASME Codejurisdiction and the functional requirements of the MNSA, the following design guidelines shall be used:
1.3.2.1 The MNSA si.all be designed using ASME Section III, Reference 3.2.1.
