{ Train A.and B conduits-carry electrical-cables essential to the safe . shutdown of the plant._ .Therefore, the conduits,.

E associated junction boxes and supports identified during the

fire safe shutdown analysis (FSSA), must- be~. capable' of l

withstanding a fire. .one fire resistive . material- used at 3 Comanche Peakito protect: conduit systems is thermolag. '

i-3 DCA 95794, revision 16-against specification : CPES-M-2032 - was -

4 written to incorporate the . additional. requirements- for installation of raceways with thermolag based.on the recent testing of thermolag-material at-Omega Labs.

l

- The purpose of this calculation -is to ' derive = unit weights, density and weights for conduits and components covered with thermolag as. listed below based - on the requirements of _ DCA j 95794, . - revision - 6.-

! A. To calculate the weight per - foot of thermolag for

[, different sizes of-conduits.

B. To calculate the equivalent density with respect to the

conduit metal area and. cables plus thermolag.

l C. To calculate the equivalent weight of fittings (weight of fitting minus conduit. run) - for different sizes of conduits when covered with thermolag.

D. To calculate- the _ additional: weight imposed by thermolag i

on-tube steel-' members and junction-boxes.

idLECOPE This calculation develops the weights due to thermolag for preshaped sections. The loads developed for both conduits and i fittings are for use in the qualification of conduit runs covered with thermolag.

The fitting weights do not represent the actual weight of the fitting plus the box thermolag but is this weight minus thn l weight of preshape thermolag already included with the conduit density.

k.,9 Hethot. ology [REr. 3, P. S G3 For weight ca4culation of conduit fittings with thermolag the following steps are considered.

l

1. Thermolag panel thickness is considered to be 1/2" minimum and 3/4" maximum.

2. For fitting dimensions, the information in reference 7 attachment B is used.

3. Thermo-lag 350 water based spill resistant topcoat is applied to thermolag. This will prevent thermo-lag from getting wet. '1hus, Wet weight is not considered in the calculation.

4. LBD with thermolag is considered to be in a box with the !

largest dimension of the LBD plus 1.5" esed.

5. The following detail is considered for unions with thermo-lag.
