> TIC121 was down to 27K > warm return valves were wide open > opened supply valves CV143 and CV146. > TIC121 went up to about 37K > Mu1 return temperature went down to about same temp as TIC121 so set Mu1 to > cold return. Open CV145 then close CV151. Mu2 return was still > TIC121 so > kept it in warm return mode. Adjust turbines as required. > After about 20 minutes Mu2 return temp dropped down to about equal to Mu1 > return temp of about 38K. Then set Mu2 to cold return. Open CV147 then > close CV143. TIC 121 drops to 30 K. Even though Mu1 and Mu2 return temps > greater than TIC121 I will keep it in //cold return mode to see if the core > solenoid temperatures will start to fall. To maximize the use of the > cooling from T2 outlet temperature CV155 is tweaked open to its maximum > stable opening. This helps cool the lower heat exchangers. If this works > then cr_c1 and cr_c12 should start to tick downwards. If they keep rising > then have to switch back to //warm return.
