30-MJ superconducting magnetic energy storage for BPA transmission line stabilizer
The Bonneville Power Administration operates the transmission system that joins the Pacific Northwest and southern California. A 30-MJ (8.4-kWh) Superconducting Magnet Energy Storage (SMES) unit with a 10-MW converter can provide system damping for low frequency oscillations. The unit is scheduled to operate in 1982. Progress during FY 80 is described. The conductor has been fully tested both electrically and mechanically, all of the necessary copper and superconductor has been purchased, and the first production lengths of cable have been fabricated. All major components of the electrical and cryogenic systems except the gas recovery unit have been received, but the refrigerator, converter, and one transformer were damaged during shipment. The dewar is being procured, and the coil support system has been designed. Support work at LASL to prepare for subsystem testing is nearly complete.

200 kW pulsed and CW gyrotrons at 28 GHz
Pulsed and CW gyrotron oscillators have been designed and constructed for use in electron cyclotron resonance heating in plasma fusion experiments. The tubes are designed for 200 kW output at 28 GHz with beam input of 80 kV and 8 A. The pulsed design has been operated at duty factors of 5% and pulse lengths up to 40 msec. The CW design has produced output of 200 kW CW with an efficiency of 50%. It also operated with 52% efficiency at an output level of 170 kW CW. The tubes are designed for power output in the TE/sub 02/ circular electric mode in oversize (2.5 inch diameter) circular waveguide. Some investigations of mode purity of the output will be described. The design and operation of waveguide components such as bends and mode filters for use with the gyrotrons will be discussed.

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
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]
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
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]
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
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
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.

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.

(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]
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 in 5';-cap methylation and in internal methylation of adenine accumulated in rats on exposure to ethionine. The methyl-deficient mRNA isolated from the liver of ethionine-fed rats differed in its translational properties from mRNA isolated from control animals. Preliminary experiments indicate that single topical application of 17n moles of TPA to mouse skin altered tRNA methyltransferases. The extent of methylation was increased over 2-fold in mouse skin treated with TPA for 48 hours. These changes have been observed as early as 12 hours following TPA treatment. In contrast, the application of initiating dose of DMBA had no effect on these enzymes. It should be emphasized that the changes in tRNA methyltransferases produced by TPA are not merely an increase of the concentration of the enzyme, rather …

Acid-base model for thy--mochemical water splitting. Results of experimental tests on manganese-based thermochemical cycles
An acid-base model for thermochemical water splitting cycles is described, together with the results of its application to cycles based upon reactions of manganese oxides. Experiments confirmed that at least 12 acids-HCl, H/sub 2/SO/sub 4/, H/sub 3/PO/sub 4/, MoO/sub 3/, NaPO/sub 3/, Na/sub 4/P/sub 2/O/sub 7/, SiO/sub 2/, Cr/sub 2/O/sub 3/, TiO/sub 2/, Al/sub 2/O/sub 3/, SnO/sub 2/, and Fe/sub 2/Onumber-drive the thermal decomposition of NaMnO/sub 2/ at temperatures below 1400/sup 0/K. Only rather strong bases-NaOH, LiOH, BaO, Li/sub 2/CO/sub 3/, Na/sub 2/CO/sub 3/-can drive the steam oxidation of Mn(II) below 1300/sup 0/K. In accord with the model, the acids HCl, H/sub 2/SO/sub 4/, H/sub 3/PO/sub 4/, and MoO/sub 3/ are too strong to be used in Mn(III)/(II) cycles, because their Na, Li, and Ba salts are too stable. Cycles were demonstrated with the other 8 acids and either NaOH or Na/sub 2/CO/sub 3/. Because such cycles evolve O/sub 2(g)/ in the presence of air, solar furnaces are appropriate sources of thermal energy for them.

Acoustic emission. Flaw relationship for in-service monitoring of nuclear pressure vessels
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 sensing system on a reactor are planned. (DLC)

Actinide cross section program at ORELA
The actinide cross section program at ORELA, the Oak Ridge Electron Linear Accelerator, is aimed at obtaining accurate neutron cross sections (primarily fission, capture, and total) for actinide nuclides which occur in fission reactors. Such cross sections, measured as a function of neutron energy over as wide a range of energies as feasible, comprise a data base that permits calculated predictions of the formation and removal of these nuclides in reactors. The present program is funded by the Division of Basic Energy Sciences of DOE, and has components in several divisions at ORNL. For intensively ..cap alpha..-active nuclides, many of the existing fission cross section data have been provided by underground explosions. New measurement techniques, developed at ORELA, now permit linac measurements on fissionable nuclides with alpha half-lives as short as 28 years. Capture and capture-plus-fission measurements utilize scintillation detectors (of capture ..gamma.. rays and fission neutrons) in which pulse shape discrimination plays an important role. Total cross sections can be measured at ORELA on samples of only a few milligrams. A simultaneous program of chemical and isotopic analyses of samples irradiated in EBR-II is in progress to provide benchmarks for the existing differential measurements. These analyses are being studied …

Actinide partitioning-transmutation program final report. VI. Short-term risk analysis of reprocessing, refabrication, and transportation: appendix
The Chemical Technology Division of the Oak Ridge National Laboratory has prepared a set of documents that evaluate a Partitioning-Transmutation (PT) fuel cycle relative to a Reference cycle employing conventional fuel-material recovery methods. The PT cycle uses enhanced recovery methods so that most of the long-lived actinides are recycled to nuclear power plants and transmuted to shorter-lived materials, thereby reducing the waste toxicity. This report compares the two fuel cycles on the basis of the short-term radiological and nonradiological risks they present to the public and to workers. The accidental radiological risk to the public is analyzed by estimating the probabilities of sets of accidents; the consequences are calculated using the CRAC code appropriately modified for the material composition. Routine radiological risks to the public are estimated from the calculated release amounts; the effects are calculated using the CRAC code. Radiological occupational risks are determined from prior experience, projected standards, and estimates of accident risk. Nonradiological risks are calculated from the number of personnel involved, historical experience, and epidemiological studies. The result of this analysis is that the short-term risk of PT is 2.9 times greater than that of the Reference cycle, primarily due to the larger amount of industry. …

Activated carbon adsorption from a high TOC wastewater
The ability of activated carbon to reduce total organic carbon in highly concentrated wastewaters from a coal gasification pilot plant was evaluated in laboratory batch and column tests. The wastewater initially contains over 5000 mg/l TOC, largely phenols and cresols, with numerous other organic species in much lower concentrations. The physical adsorption process is best explained by the Freundlich model, with the slope and intercept of the Freundlich isotherm comparable to data reported for treatment of refinery wastes. Carbon exhaustion rates and bed depth-service time curves are also comparable to refinery treatment data obtained from waters of lower TOC or COD. Laboratory-scale column tests reduced TOC from 5740 mg/l to 200 mg/l.
