MCC-133 and MCC-43

• Condensate Service Stations/Demin or Firehose
• Filter demin back wash connection
• RHRSW via RHR
• Fire Water via RHR
• Precoat Pump
• RHR suction from Torus

• Assumes 141 bundles are dishcarged every 18 mos, 96 hrs of cooling have occurred.
• Heat load per discharge batch is 5.6 mil BTU/hr
• Heat load decreases rapidly
• The next disch to the HDFSS adds another 5.6 mil BTU/hr

• Discharge is req'd 30 days following the last refueling discharge and fills the final 484 spaces in the HDFSS.
• Full core disch is completed within 150 hrs of shutdown.
• Calculated heat load is 19 mil BTU/hr, RHR would be used, as necessary, in order to cool the full-core discharge.
