5MW Raft River facility experience
Description:
The Raft River geothermal plant is a small binary cycle conversion system which uses isobutane as the working fluid. This plant uses a staged boiler concept to achieve better performance than could be obtained by a single boiler. The plant was designed to operate with a geothermal water inlet temperature of 143/sup 0/C (290/sup 0/F) and produce a nominal generator output of 5MW. The plant is supported by a supply and injection system consisting of three supply wells (about 1524m or 5000 ft deep…

85Kr management trade-offs: a perspective to total radiation dose commitment
Description:
Radiological consequences arising from the trade-offs for /sup 85/Kr waste management from possible nuclear fuel resource recovery activities have been investigated. The reference management technique is to release all the waste gas to the atmosphere where it is diluted and dispersed. A potential alternative is to collect, concentrate, package and submit the gas to long-term storage. This study compares the radiation dose commitment to the public and to the occupationally exposed work force fro…

Ability of the TRAC-P1A computer program to predict blowdown, refill, and reflood phenomena during Semiscale Mod-1 experiments. [PWR]
Description:
A computer analysis of a Semiscale Mod-1 Loss-of-Coolant Experiment (LOCE) was performed using the TRAC-P1A computer program. The main purpose of this analysis was to contribute data for the assessment of the ability of TRAC-P1A to predict blowdown, refill, and reflood phenomena during a postulated Loss-of-Coolant Accident (LOCA). A TRAC-P1A Semiscale Mod-1 system model was created and TRAC-P1A was used to obtain initial conditions for Semiscale Mod-1 LOCE S-04-6. After this initialization, TRA…

Absolute measurement of anti. nu. for /sup 252/Cf
Description:
Neutron yields were determined by measuring the activities produced in the INEL manganese bath. Of the three fission methods used, the neutron-fission coincidence method was found to be the most consistent and reliable. The value of /sup 252/Cf anti ..nu.. obtained by these measurements was 3.764. (RWR)

Absolute Photodissociation Quantum Yields for the NO3 Free Radical
Description:
The nitrate free radical was photolyzed by a pulsed tunable dye laser between 470 and 685 nm, at 296 K, and in the presence of 10 torr N{sub 2}. The two product channels, NO + O{sub 2} and NO{sub 2} + O, were measured by resonance fluorescence of NO or of O. Absolute calibration of the method was achieved by in situ ultraviolet photolysis of NO{sub 2}, which yields both NO and O. With these data on photochemical yields, the photolysis coefficients for the two product channels at the surface of …

Absolute polarization standards at medium and high energies. [200 to 900 MeV]
Description:
Although measurement of a polarization asymmetry is rather easy, the normalization of the measurement to obtain the analyzing power requires an absolute knowledge of the beam polarization or comparison with a known standard analyzing power. Such calibration standards can be hard to find. This paper concentrates on medium and higher energies, and divides the techniques into four categories: double scattering, polarized target methods, polarized source methods, and theoretical methods. Secondary …

ac power control in the Core Flow Test Loop
Description:
This work represents a status report on a development effort to design an ac power controller for the Core Flow Test Loop. The Core Flow Test Loop will be an engineering test facility which will simulate the thermal environment of a gas-cooled fast-breeder reactor. The problems and limitations of using sinusoidal ac power to simulate the power generated within a nuclear reactor are addressed. The transformer-thyristor configuration chosen for the Core Flow Test Loop power supply is presented. T…

Acceleration of polarized proton at the AGS
Description:
The unexpected importance of high energy spin effects and the success of the ZGS in correcting many intrinsic and imperfection depolarizing resonances led us to attempt to accelerate polarized protons in the AGS. A collaborative effort is underway by the groups in Argonne, Michigan, Rice, Yale and Brookhaven to improve and modify the AGS to accelerate polarized protons. With the appropriate funding the first polarized proton acceleration at the AGS should be possible by 1983.

Accelerator Mass Spectrometry and Radioisotope Detection at the Argonne FN Tandem Facility
Description:
The Argonne FN tandem accelerator and standard components of its experimental heavy-ion research facility, have been used as a highly-sensitive mass spectrometer to detect several long-lived radioisotopes and measure their concentration by counting of accelerated ions. Background beams from isobaric nuclei have been eliminated by combining the dispersion from the energy loss in a uniform Al foil stack with the momentum resolution of an Enge split-pole magnetic spectrograph. Radioisotope concent…

Accident assessment: role of the containment radiation monitor
Description:
The containment radiation monitor may provide information to a power reactor operator that can aid assessment of the degree of core damage following a loss-of-coolant accident (LOCA). This paper reports calculations of the exposure rates that would exist in the containment of a commercial pressurized water reactor (PWR) following severe reactor transients. The results indicate exposure rates of 1 to 2 R . h/sup -1/ 30 minutes after a large LOCA, 4 to 5 x 10 R . h/sup -1/ one hour following a re…

(Accumulation of Methyl-Deficient Rat Liver Messenger Ribonucleic Acid on Ethionine Administration). Progress Report. [Methyltransferase Activity in Ehrlich Ascites Tumor Cells and Effects of Phorbol Ester on Methyltransferase Activity]
Description:
Enzyme fractions were isolated from Ehrlich ascites cells which introduced methyl groups into methyl deficient rat liver mRNA and unmethylated vaccinia mRNA. The methyl groups were incorporated at the 5'; end into cap 1 structures by the viral enzyme, whereas both cap 0 and cap 1 structures were formed by the Ehrlich ascites cell enzymes. Preliminary results indicate the presence of adenine N/sup 6/-methyltransferase activity in Ehrlich ascites cells. These results indicate that mRNA deficient …

Acoustic emission. Flaw relationship for in-service monitoring of nuclear pressure vessels
Description:
Acoustic emission (AE) testing has the potential of being a valuable NDI method with capability for continuous monitoring, high sensitivity, and remote flaw location. Tests of the method were carried out on ASTM A533 Grade B, Class 1 steel. Crack growth AE signals could be recognized. An AE/fracture mechanics relation was developed for flaw interpretation. Two intermediate vessel tests at ORNL under the HSST program were analyzed. A simulated reactor vessel test and installation of an AE sensin…
