INTRODUCTION 1

The following tables are revisions of those in Stone & Webster's

" Fire Protection Per Appendix R Requirements Ampacity Study."

These tables are to be revised as plant modifications (which affect these trays or any safe shutdown cables) are implemented.

The tables should also be revised when the loads of any of the affected cables (Table 4) are changed. For further explanation of the original study, see Reference 1.

Terms:

Tray Width - given in inches .

Tray Length - given in feet Tray Loss - UA, from Table 2 Watts / Foot - q from cable's amps and ohms /f t Delta T - Delta T = q/UA Derating Factor - Taken from Table 7 by applying Delta T Heat Transfer Formula - q = UA (Delta T)

Table 8-B lists cables to be wrapped which are in conduit. The

" conduit loss" (U x A) values are calculated using the method.

described in Reference 4. Page 2 of the Design Review Report of Ref. 4 contains an error - the K 3 and h c yglues for kaowool should read .025 Btu /Hr-Ft- F and 1.307 Btu /Hr-Ft - F respectively. All conduit loss calculations in Table 8-A of this report are adjusted with the correct values of K and h for kaowool. Any revisions to Tables 8-A and 8-B should use ca1culations described in Method-2 of Ref. 4, taking into account the correct values of K and h C for kaowool. The "derated cable ampacity" is ' derived by ahplying the derating factor and service factor (1.25) to the cable ampacity.

Table 8 Terms: .

Conduit Loss - given in W/Deg - C per linear foot Wrap - K = Kaowool T = Thermolag Cables added to this report that have NSP type numbers other than those already listed in the report need not be designated with their actual type numbers. If a cable has the same size, voltage rating, resistance, and insulation style yielding the same ampacity of an existing type shown on Tables.1 and 3, then this report's existing type number may be used for the cable's designation. The NSF type numbers on this report are only used -

as a reference from Tables 4, 5, and 8 back to Tables 1 and 3.
