JUI. :3 8dO 2 6 7 2 25 INTRODUCTION Regulatory Guide 1.84 states, " Code Case N-192 is acceptable subject.

to the following conditions in addition to those conditions specified in the Code <C~ase: The applicant should indicate system application,

. design and operating pressure, and pressure-temperature rating of the flexible hose. Data to demonstrate compliance of the flexible hose with NC/ND-3649, particularly NC/ND-3649.4(e), arc required to be furnished with the application." Submittal of this report to the NRC is intended to satisfy these additional regulatory requirements for the Hope Creek Generating Station.

DISCUSSION ASME Code Case N-192 provides the design guidance for the fabrication of flexible hose coenections. Flexible connects complying with Code Case N-192 are used at HCGS on instrument impulse lines and on the standby diesel generator (SDG) skids. Atta chments 4.1 t.hrough 4.8 were complied to demonstrate compliance with Paragraph NC/ND-3649 of the A SME Co de . Attachments 4.1 through 4.4 apply to those connectors on the instrument lines and Attachments 4.5 through 4.8 apply to the skid-to-facility connectors on the SDGS.

i Flexible Metal Hoses for the Hope Creek Generating

- Station

1) Hoses shall be designed, manufactured, examined, tested, stamped and documented in accordance with the Code.

2) Pressure boundary items are defined as including flexible metal bellows or tubes, end tubes and adaptors. The external flexible wire braid may act as an axial pressure thrust restraint and provide columnar stability against squirm.

3) Design pressure and temperature shall be 2500 psig and 700*F respectively. The ranges of process fluid temperatures and pressures are 31*F to 5758F and atmospheric to 1250 psig, respectivsly.

. 4) Design motion shall be 5 inches in ar.y one direction and return to installed position for b50 design cycles.

5) Hoses shall be marked to show the direction of flow if applicable.
