Consultant recommends subsidies for Exelon plants
A research and consulting firm hired by Illinois governor J. B. Pritzker’s administration to scrutinize the financial fitness of Exelon’s Byron and Dresden nuclear plants approves of limited state subsidies for the facilities, according to a redacted version of the firm’s report made available yesterday.

An original method, based on the continuous circulation in a closed circuit of saturated HTO vapour, is presented. The saturated vapour are obtained by bubbling from vials containing different tritium standard solutions (IFIN-HH-TDCR method). The main difference from the usual method, elaborated by Osborne, is the use of saturated vapour, which eliminates the measurement in liquid scintillator of the recovered non-saturated vapour. Tritium Monitors type MT-1 made in IFIN-HH were calibrated. The measurements were carried out for three levels of the activity concentration: 0.0180, 0.701 and 1.73 MBq.g-1. The mean response was R=2.25.10-13 A/(MBq m-3) with a relative combined uncertainty lower than 4%. The value agrees with the result obtained with the Osborne method, ROs=2.30.10-13A/(MBq m-3) and with the estimated theoretical value, 2.29 10-13A/(MBq m-3)
