BZP 380-T4 Revision 2 Estimate of RCS Mass 1.
obtain the reactor coolant volume additions for the following:
Estimated Volume Maximum Volume Tank Added Added (callons) a.
Refueling Water Storage Tank 495,000 b.
Accumulator A 7,217 c.
Accumulator B 7,217 d.
Accumulator C 7,217 e.
Accumulator D 7,217 f.
Boric Acid Storage Tank 48,000 g.
Residual Heat Removal System 5,000 h.
Otner source Total 2.
Convert gallons to grams as follows:
Total reactor coolant system volume added:
, gallons x 3785 gas / gal =
gas 3.
Determine the Reactor Coolant System Mass as follows:
3.22E8 grams x system specific gravity
- grams
=
4.
Determine the Total Liquid Mass as follows:-
RCS Mass grams + Added Mass grams =
graw System Specific Gravity is determined from BZP 380-AB, page 2.
