Fission-product afterheat: a review of experiments pertinent to the thermal-neutron fission of $sup 235$U

PDF Version Also Available for Download.

Description

Experimental data relating to beta and gamma energy release rates following thermal-neutron fission of /sup 235/U are reviewed. An afterheat function based on these experiments, for after-shutdown times from 1 s to 5 x 10/ sup 5/ s, is proposed and compared with the proposed ANS Standard ANS-5.1; and the uncertainty in the function proposed here is estimated. This proposed function varies between 0.98 and 1.08 times the proposed standard function; the standard deviation is estimated to be between 10% and 15%. (31 figures, 17 tables, 48 references) (auth)
