700, 100, and 20 hp combustion test facility yearly activity report for the period April 1, 1979 to April 1, 1980 (open access)

700, 100, and 20 hp combustion test facility yearly activity report for the period April 1, 1979 to April 1, 1980

Management and Technical Services Co./ General Electric was awarded the contract to operate, modify and maintain the DOE/PETC 700 hp, 100 hp, and 20 hp Combustion Test Facility. These facilities were designed and built by the Department of Energy at Pittsburgh Energy Technology Center and its ultimate success is the responsibility of DOE/PETC. MATSCO/GE will provide support to assist in the goal of successful operation of this pilot plant facility. The primary objective of the DOE/PETC 700 hp and 100 hp CTF is to establish the practicality of coal oil slurry combustion as a technically, economically and environmentally feasible retrofit technology. The 20 hp CTF is to provide a test bed to evaluate synthetic fuels for its technical feasibility and its effect on the environment. Four series of combustion tests were completed. Coal-oil mixes for all tests were number 6 fuel oil and Pittsburgh Seam Coal. The tests were executed successfully. Operational problems were handled as required without excessive delay of the testing program. Additional studies performed concurrently with the combustion testing included flame studies, stack emissions studies during all tests, standard measurements of equipment wear after each test series and extensive erosion and corrosion analyses of boiler test coupons …

5MW Raft River facility experience (open access)

5MW Raft River facility experience

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) and two injection wells (about 1158m or 3800 ft deep). Experience in several important areas: environmental, supply and injection system, and power plant, are discussed. (MHR)

85Kr management trade-offs: a perspective to total radiation dose commitment (open access)

85Kr management trade-offs: a perspective to total radiation dose commitment

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 from these alternatives. The results indicate that it makes little difference to the magnitude of the world population dose whether /sup 85/Kr is captured and stored or chronically released to the environment. Further, comparisons of radiation exposures (for the purpose of estimating health effects) at very low dose rates to very large populations with exposures to a small number of occupationally exposed workers who each receive much higher dose rates may be misleading. Finally, cost studies (EPA 1976 and DOE 1979a) show that inordinate amounts of money will be required to lower this already extremely small 80-year cumulative world population dose of 0.05 mrem/person (<0.001% of natural background radiation for the same time period).

Ability of the TRAC-P1A computer program to predict blowdown, refill, and reflood phenomena during Semiscale Mod-1 experiments. [PWR] (open access)

Ability of the TRAC-P1A computer program to predict blowdown, refill, and reflood phenomena during Semiscale Mod-1 experiments. [PWR]

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, TRAC-P1A was used to simulate the first 60 seconds of this experiment. The results of this simulation are presented and discussed.

Absolute Photodissociation Quantum Yields for the NO3 Free Radical (open access)

Absolute Photodissociation Quantum Yields for the NO3 Free Radical

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 the earth with an overhead sun over wavelengths 470-700 nm are calculated to be j{sub 1}(NO + O{sub 2}) = 0.022 {+-} 0.007 s{sup -1} and j{sub 2}(NO{sub 2} + O) = 0.18 {+-} 0.06 s{sup -1}.

Absolute polarization standards at medium and high energies. [200 to 900 MeV] (open access)

Absolute polarization standards at medium and high energies. [200 to 900 MeV]

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 standards are also discussed, and earlier data are assessed. 52 references, 6 figures. (RWR)

ac power control in the Core Flow Test Loop (open access)

ac power control in the Core Flow Test Loop

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. The initial considerations, design, and analysis of a closed-loop controller prototype are detailed. The design is then analyzed for improved performance possibilities and failure modes are investigated at length. A summary of the work completed to date and a proposed outline for continued development completes the report.

Acceleration of polarized proton at the AGS (open access)

Acceleration of polarized proton at the AGS

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 (open access)

Accelerator Mass Spectrometry and Radioisotope Detection at the Argonne FN Tandem Facility

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 concentrations in the following ranges have been measured: /sup 14/C//sup 12/C = 10/sup -12/ to 10/sup -13/, /sup 26/Al//sup 27/Al = 10/sup -10/ to 10/sup -12/, /sup 32/Si/Si = 10/sup -8/ to 10/sup -14/, /sup 36/Cl/Cl = 10/sup -10/ to 10/sup -11/. Particular emphasis was put on exploring to what extent the technique of identifying and counting individual ions in an accelerator beam can be conveniently used to determine nuclear quantities of interest when their measurement involves very low radioisotope concentrations. The usefulness of this method can be demonstrated by measuring the /sup 26/Mg(p,n)/sup 26/Al(7.2 x 10/sup 5/ yr) cross section at proton energies in the astrophysically interesting range just above threshold, and by determining the previously poorly known half life of /sup 32/Si.

Accident assessment: role of the containment radiation monitor (open access)

Accident assessment: role of the containment radiation monitor

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 release of the gap activity, and 4 . 10/sup 6/ R . h/sup -1/ two hours after a transient that resulted in a fuel melt. Furthermore, differences between the energy spectra of photons released by noble gases and halogens suggest that containment radiation monitors may be designed to differentiate between these radioelements. The calculated exposure rates are not in agreement with the response of containment radiation monitors during the incident at the Crystal River Reactor. Inhomogeneous source terms, the operation of containment building systems, and inaccuracies in release estimates, measurements and calculations may have contributed to this discrepancy in one degree or another.
