0 INTRODUCTION

This report CR 729, was prepared by Metal Bellows Corporation (MBC) ChatsworthCalifornia for the Tennessee Valley Authority, Knoxville, Tennessee, in accordance with TVA Specification Number BNP-DS-19404809-RO

This report provides the design analysis for a inch hose assembly . with 3/8 inch tube ends, for use in Bellefonte Nuclear Plant in various locations and applications. Actual operating conditions are less than design requirements.

The analysis is in accordance with the Rules of the ASME Boiler and Pressure Vessel Code Section III, Class 2. A simplifying, conservative assumption is to analyze the hose and braid separately. Association (EJMA) performance equations. and ignores the hoop support provided by the braid. The. analysis of the braid is to show the stresses imposed by the' pressure end loads is within Code allowables. The braid inward force vector far exceeds the squirm force created by the hose, and bellows squirm calculations are ignored.

A simplifying, conservative approach is to list the many possible motions and radius changes that will occur and perform the stresslife calculations for the single worst case. The seismic analysis is made assuming the .hose is full of air and pressurized.

The mechanically induced vibration is analyzed at 10 Hz only. The other required frequencies will produce smaller displacements with resulting higher life and need not be considered.

The hose is identical to MBC.P/N 73989 which has been seismic and cycle tested, reference CR 725.

Using configuratiol @ (See Figure 1) measured center line bend radii as hose was moved thru required motions:

NOTE: COnfiguration indicated greatest changes.

Condition I: Free end moves up 5 in. (+Y), center radius changes from. 7. 5 in. (installed) to 4. 5 inches.

Condition II: Free end moves down 5 in. (- Y), center radius changes from 7. 5 in. to 10. 5 in. and straight ends to 11. 0 in,

Condition III: Free end moves horizonally (+X) straight hose develops same 7. 5 in. radius and radius becomes straight.

Condition IV: Free end moves out of paper (Z), radius does not change and 900 to radius, hose develops 2nd radius where hose goes into offset.
