Public Workshop, Staff Technical Meeting with Applicant on Geysers Unit 17

Description: The overall purpose of this meeting is to discuss the report that was sent to PG and E on February 1st discussing Geysers 17. The Commission has reviewed all of the existing data, the majority of the existing data that have gone through both Lake County and through the CPUC regarding 17, looked at the existing data to see what, if any, additional would be required to file and expeditiously process a Notice of Intention on Geysers Unit 17.

Determination of performance criteria for high-level solidified nuclear waste from the commercial nuclear fuel cycle: a probabilistic safety analysis

Description: To minimize the radiological risk from the operation of a waste management system for the safe disposal of high-level waste, performance characteristics of the solidified waste form must be specified. The minimum waste form characteristics that must be specified are the radionuclide volatilization fraction, airborne particulate dispersion fraction, and the aqueous dissolution characteristics. The results indicate that the pre-emplacement environs are more limiting in establishing the waste form… more

Thermodynamic characterization of liquid metals at high temperature by isobaric expansion measurements

Description: Results of isobaric expansion measurements for platinum are presented, including simultaneous values for enthalpy, specific volume, temperature and electrical resistivity in tabular form as well as numerical fits up to 7500 K. The specific heat for the liquid is C/sub p/ = 5.85 +- 0.30 R and is essentially constant up to 7500 K. The bulk thermal expansion coefficient increases from approx. 7.5 x 10/sup -5/K/sup -1/ at melt to approx. 1.03 x 10/sup -4/K/sup -1/ at 7500 K. The heat of fusion obse… more

Modeling the performance of a two-phase turbine using numerical methods and the results of nozzle, static cascade, and windage experiments

Description: Performance models for a two-phase turbine were developed to verify the understanding of the loss mechanisms and to extrapolate from the single-nozzle test condition to a full-admission turbine. The numerical models for predicting the performance of the nozzle and the combined nozzle and rotor are described. Results from two-phase, static cascade tests and disk-friction and windage experiments are used to calibrate the performance model(s). Model predictions are compared with single-nozzle prot… more

Modified diamond dies for laser applications

Description: A modified wire drawing die for spatial filtering techniques is described. It was designed for use in high power laser systems. The diamond aperture is capable of enduring high intensity laser frequency without damaging the laser beam profile. The diamond is mounted at the beam focus in a vacuum of 1 x 10/sup -5/ Torr. The vacuum prevents plasma forming at the diamond aperture, thus enabling the beam to pass through without damaging the holder or aperture. The spatial filters are fitted with a … more

Digital interface for NDT instruments

Description: In order to obtain access to a computer from ordinary NDT instruments, a special interface was made which acts as the buffer between the computer, and the real world. The special purpose interface, which was designed and built by Group M-1 of the Los Alamos Scientific Laboratory is described. This interface was primarily built for use with various ultrasonic equipment, but is actually a general purpose system that can perform data acquisition and control for other tests.

NWCF maintenance features and capabilities

Description: A New Waste Calcining Facility is being built at the Idaho Chemical Processing Plant to replace the existing Waste Calcining Facility which was built to demonstrate fluidized-bed solidification of highly radioactive liquid wastes. The new facility is being designed to provide a higher waste throughput, more corrosion resistant materials of construction, more effective cleanup of effluent streams, and extensive remote maintenance and equipment replacement capability. The facility will also conta… more

Production of einsteinium and fermium in nuclear explosions

Description: Efforts devoted to searches for short-lived nuclides in the debris from large thermonuclear explosions are reviewed along with reactor production of Es and Fm. Results of underground tests are discussed along with odd-even yield variations, and future directions for heavy-element synthesis. (JRD)

Studies of Closure Phenomena in Pinholes Irradiated by Nd Laser Pulses

Description: The plasma closure of spatial filter pinholes is a critical parameter in the performance of high energy glass laser systems. Using 50 to 100 J, 300 psec FWHM laser pulses on the Janus laser, an investigation has been made on closure effects in 300 ..mu..m to 500 ..mu..m diameter pinholes of various materials and thicknesses. Calorimetry measurements have yielded data on pinhole transmission and intensity loading on the periphery of the pinhole. Ultrafast streak photography measurements indicate… more

Dynamic range studies of the RCA streak tube in the LLL streak camera

Description: As indicated by tests on several cameras, the dynamic range of the Lawrence Livermore Laboratory streak-camera system appears to be about two orders of magnitude greater than those reported for other systems for 10- to 200-ps pulses. The lack of a fine mesh grid in the RCA streak tube used in these cameras probably contributes to a lower system dynamic noise and therefore raises the dynamic range. A developmental tube with a mesh grid was tested and supports this conjecture. Order-of-magnitude … more
