Braidwood is a Westinghouse 4-Loop PWR with core duty index of 157 (U2) to 182 (U1).
U1 = A1R17 (pre-outage) 3.2 E-4 U2 = A2R17 (currently 14 weeks before outage, deboration first starting so number will increase) 6.8 E-5 We have seen much higher numbers in the past. A1R10 was highest at 8.7 E-3 while A1R17 was lowest. We also now clean up RWST very well. We were at 3.1 E-8 before our last outage - that is substantial so when cavity fill is complete the water can get a good dilution.
