High temperature fission product chemistry and transport in steam. [PWR; BWR]
The High Temperature Fission Product Program, an experimental and analytical effort to produce thermodynamic and reaction-rate data on fission product species during severe LWR accidents, is reviewed. The paper discusses: (1) a facility where non-radioactive isotopes of fission products react with steam, reactor materials, and hydrogen for periods of time from seconds to hours at temperatures up to 1100/sup 0/C; and (2) recent results of vapor phase studies with CsOH as well as CsI in a 304ss or Inconel 600 system with steam and hydrogen and, in the absence of steam and hydrogen, reactions of tellurium vapor with nickel, 304ss, Inconel 600, preoxidized 304ss, preoxidized Inconel 600 and silver, iodine vapor with silver, CsOH with iodine and with HI and CsI with Ag and with O/sub 2/.
