Blowdown/reflood testing of two heater rods containing laser welded thermocouple attachments is described. Two series of tests were conducted, one of three and another of nine blowdowns. Test parameters were controlled such that the blowdown/reflood cycles duplicated those predicted for the LOFT reactor. Thermocouple performance throughout the test series was very good in that the only failures observed were caused by bowing of the heater rod. Data from all tests are included as are photographs of laser welds taken at various times during the test series. Although heater rod bowing did cause failure of some of the welds, actual fuel pins are restrained and thus not expected to bow to this extent. When weld failure does occur it appears in the form of a separation at the bond between the Titanium fillet and Zircaloy. This does not impair either the performance or the integrity of the fuel cladding in any way.

An rf system is described for the 500-MHz cylindrical resonator that is coupled to the Astron beam to modulate its energy by +- 1.5 percent.

Because of recent breakthroughs in the target area, and in the glass laser area, the scientific feasibility of laser fusion--and of inertial fusion--may be demonstrated in the early 1980's. Then the development in that time period of a suitable laser (or storage ring or other driving source) would make possible an operational inertial fusion reactor in this century. These are roughly the same time scales as projected by the Tokamak magnetic confinement approach. It thus appears that the 15-20 year earlier start by magnetic confinement fusion may be overcome. Because inertial confinement has been demonstrated, and inertial fusion reactors may operate on smaller scales than Tokamaks, laser fusion may have important technical and economic advantages.

Short beam usage times were encountered using a 60 keV electron beam welder. These short times were the direct result of a buildup of a reaction product (WO/sub 2/./sub 90/) that occurred on graphite washers which housed the tungsten emitter plate. While it was not possible to prevent the reaction product, its growth rate was sufficiently altered by changing graphite materials and minor design changes of the washers. With these modifications beam usage times increased from an original 40 min to approximately 675 min.

The DT fusion neutron irradiation of one LLL superconductor wire and one LLL Nb/sub 3/Sn foil at 4.2/sup 0/K is described. The sample position, beam-on time, and neutron dose record are given. The results from two ''profile'' dosimetry foils measuring the lateral variation in neutron flux are included.

Computations have been made of the parameters of a neutral-beam driven, field-reversed mirror reactor as a function of beam injection energy. Q values of 4 to 5 and a fusion power of 10 to 50 MW per cell are found at beam energies of 200 to 500 keV. Cost estimates indicate a direct capital cost of less than $1000/kW/sub e/ for multicell versions of the reactor.

A weekly publication, the Texas Register serves as the journal of state agency rulemaking for Texas. Information published in the Texas Register includes proposed, adopted, withdrawn and emergency rule actions, notices of state agency review of agency rules, governor's appointments, attorney general opinions, and miscellaneous documents such as requests for proposals. After adoption, these rulemaking actions are codified into the Texas Administrative Code.

Anomalous transmission due to diffraction from the (220) planes of germanium has been measured for 1.65 mm, 8.58 mm, and 19.6 mm thick single crystals at energies ranging from 15 to 55 keV. A method of producing a continuously variable, in energy, source of nearly monoenergetic x-rays based on anomalous transmission and a bremsstrahlung input spectrum is described. Collimator design, crystal selection, crystal preparation, peak shapes, full-widths at half-maximum, and intensities for fixed crystals are discussed and compared to theory. The anomalous transmission factors ranged from 1 x 10/sup -7/ to 5 x 10/sup -6/ resulting in usable intensities of 2.5 to 37 photons per sec for tungsten target bremsstrahlung input spectra.
