Service Water Modeling Glen, It is my understanding that should normal service water need to be isolated from the Class portion of the Divisions, it is done by closing MOVs 36 and 37, thus separating the Divisions also. For some reason, the simplified drawing that was provided to INEEL showed the isolation by an MOV-1 17 on the nonclass portion of the piping. Could you verify which is correct?

Additionally, I need to know the nonclass isolation signals and what the system success criteria would be if the nonclass piping did not isolate as designed.

Thanks for your assistance and patience as we update our model. I believe that it will be in all our best interests to have a valid SPAR.

Thanks, David y-/0
