Gasbuggy 1973 production testing

Description: The 1973 Gasbuggy production tests were designed to determine what, if any, changes have occurred in the producing characteristics of the Gasbuggy chimney over a four-year period. In May 1973, gas production from the GB-ER well was resumed. A rapid drawdown of the chimney pressure from 736 psig to about 250 psig was completed in 23 d. A total of 71.4 M/sup 2/ ft/sup 3/ of gas was produced and flared in this part of the test. Flow rates ranged from 4.9 to 1.8 M/sup 2/ ft/sup 3/d. The test continued by adjusting the flow rate so that the bottom-hole pressure would remain essentially constant. This part of the test ended on October 23, 1973. Another drawdown to 129 psig was completed on November 8, 1973. The pressures during 1973 production tests approximately duplicate those for the latter portion of the 1969 production tests. The drawdown data indicate that the chimney void volume is about the same as it was in 1969. This observation, in conjunction with the measured tritium content of water produced reveals that the amount of water, if any, entering the chimney since 1969 has averaged less than one-tenth of a gallon per minute. In addition, only amounts of water normal for its vapor pressure at the chimney temperature have been produced with the gas, confirming that the leak from the Ojo Alamo aquifer, which sealed itself in 1969, has not reopened. The radioactive concentrations in the gas have been continuously measured by the El Paso On-Line Monitor System, and by an E.P.A. burner. Maximum tritium and /sup 85/Kr concentrations during drawdown were 0.236 and 0.066 mu Ci/SCF (at 15.025 psia and 60 deg F) respectively. Fresh gas flowing into the chimney region has since reduced these levels. The effect of influx near the top of the ...

Earth sciences waste disposal investigations, July--December 1965

Description: The Hanford Project has over 500 wells which are used for the surveillance of radionuclides in the ground resulting from waste disposal. Wells are located at disposal sites to monitor the migration of radionuclides in the soil and to determine when a disposal facility is to be abandoned. Outside of the immediate disposal areas, wells are sampled to determine the movement of contaminants in the ground water zone. The spread of wastes in unconfined ground water aquifers is followed by routine sampling, and the confined aquifers in the area are sampled frequently where possible. Maps of gross BETA and tritium concentrations in the ground water are presented to define contamination spread from the disposal areas during the last six months of 1965. (auth)

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

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.
