CONCEhTRATION OF SOLIDS IN TMI-1 VESSEL FOLLOWING COLD-LEG BREAK For certain cold-leg breaka for TMI-1, heat removal will probably be by evaporation alona. The potential for buildup of solida exists.
Please calculate that potential for the following conditions:
1.
Vessel caracity-2500 ft3 liquid, or 18,750 gal.
2.
Liquid 'ieuperature 200*F
~-
3.
Initial Baron concentration 1000 ppa.
4..
Boiloff Rates
~.
a.
0-30 mia.:
" 300 gym b.
30 mia.-24 hr.: 150 spa 5.
Incoming Water a.
0 - 30 mia.:
1 lb H 303 per 8 gal water 3
11h NaOH per 12 gal water b.
30 min.-24 hr.:
12h H 503 per 14 gal water 3
1 lb NaOH per 22 gal water 1 lb Ma2 2 3 per 12 gal water 80 The fund==atal question to be resolved in whether the dissolved solids will remeia dissolved. Certainly there will be a time that saturation will be reached if boiloff is continuous. We are discussing the thermal aspects with E4:W currently.
-As a scoping calculat: 9, datarmine the extent to which saturation is reached at the end of 14 hours1.62037e-4 days <br />0.00389 hours <br />2.314815e-5 weeks <br />5.327e-6 months <br />.
