Characterization of stack effluents from certain nuclear facilities. Final report, April 1, 1972--June 30, 1973

PDF Version Also Available for Download.

Description

BS>Nuclear power reactors produce copious quantities of several species of permanent gas radioactivity, some directly by fission and others by neutron activation of reactor materials and coolants. The gaseous effluents from a boiling-water reactor (BWR), two pressurized light-water reactors (PWR), a high- temperature gascooled reactor (HTGR) and a pressurized heavy-water research reactor (PHWR) have been analyzed for radioactive and stable constituents. In the case of the BWR, direct stack sampling has insured representative sampling. The PWRs, HTGR, and PHWR do not provide for direct stack sampling, so analyses of hold-up tank gas, pressure-vessel gas, cover gas, primary-coolant strip-gas, and containment ... continued below

Description

BS>Nuclear power reactors produce copious quantities of several species of permanent gas radioactivity, some directly by fission and others by neutron activation of reactor materials and coolants. The gaseous effluents from a boiling-water reactor (BWR), two pressurized light-water reactors (PWR), a high- temperature gascooled reactor (HTGR) and a pressurized heavy-water research reactor (PHWR) have been analyzed for radioactive and stable constituents. In the case of the BWR, direct stack sampling has insured representative sampling. The PWRs, HTGR, and PHWR do not provide for direct stack sampling, so analyses of hold-up tank gas, pressure-vessel gas, cover gas, primary-coolant strip-gas, and containment air were required to derive characteristic patterns of gas releases from these reactors. Gamma-emitting gaseous species Were measured spectrometrically using a Ge(Li) detector. Chromatographic separation of various gas fractions on a series of molecular sieve columns permitted the use of internal gas-proportional counting tubes for spectrometric resolution of beta- emitting gas species. In addition to measurement of gammaemitting noble gases, / sup 3/H (as a hydrogen gas and methane), /sup 14/C (as methane and carbon dioxide), /sup 37/Ar and /sup 36/Ar have been quantitatively identified. Higher hydrocarbon, carbon monoxide, and methyl iodide fractions in the gaseous effluents contained only very low quantities of radioactivity. Estimases are provided of total annual release of the several species. relative release rates as compared to control requirements, and estimates of long-range transport of / sup 37/Ar as compared to atmospheric measurements performed by other laboratories.
