Methods for Computing Manpower Requirements for Weapon Systems Under Development

Description: Report discussing a method developed for an accurate and comprehensive forecasting of manpower requirements for new weapon systems. Plans are presented for an approximation of the effect of environment upon manning requirements, for the determination of manhours required for work of a type not amenable to direct task analysis, and for the estimation of maintenance activity frequency rates.

LT-1, a General Reactor Lifetime Program for IBM-7090

Description: The LT-1 code calculates isotopic concentrations, absorption and fission rates, effective multiplication, and flux ration as a function of time for an infinite heterogeneous or homogeneous medium. A leakage correction if applied. Both equilibrium and batch loaded cycles are covered, and both thorium and U238 systems. Absorptions in control material are assumed at each point in time so that the flux ratios are always characteristic of the just-critical system.

Thorium Breeder Reactor Evaluation. Part I, Fuel Yields and Fuel Cycle Costs of a Two-Regional, Molten Salt Breeder Reactor

Description: The MSBR (1000 Mwe station) is capable of giving fuel yields of about 75/yr (doubling time = 14 years0 at a fuel cycle cost of approximately 1.5 mills/kwhr. At fuel yields of 1 to 2%/yr (DT = 100 to 50 years), the fuel cycle cost extrapolates to 0.65 mills/kwhr; at 4%/yr (DT = 25 years), the fuel cycle cost is about 0.85 mills/kwhr. All system were optimized with respect to fuel cycle processing time.

Eurochemic Assistance Program: Progress Report for June, 1960 Through July, 1961

Description: The Eurochemic organization has been modified to include special contact groups for the architect-engineers. The current plant design capacity is 350 kg/day of natural uranium in aluminum or magnesium cladding and 200 kg/day of slight enriched uranium (5% max) in stainless steel and Zircoloy cladding. The processing of higher enrichment uranium (20 to 90%) is being considered. The pre-project design is essentially complete and projecting work has been started by three of the eight architect-eng… more

OC-ORR Loop No. 2 Check Valve Tests

Description: Air pressure drop and helium back-leakage tests have been conducted on ball-check valves proposed for use in the OC-ORR Loop No. 2. These valves are being installed to prevent the bypassing of helium thru either of the paralleled compressors when one is inoperative. t is concluded that incompressible-flow loss coefficients adequately describe the pressure drop characteristic over the flow range investigated and, on this basis, curves of helium pressure drop vs flow rates and Reynolds' number ha… more

Solution Critical Experiments for the High Flux Isotope Reactor: Preliminary Calculations

Description: A condensed version of this report was presented on December 12, 1960 at the San Francisco meeting of the American Nuclear Society under the title Solution Critical Experiments for High Flux Isotope Reactor Studies, Part B Calculations. Nuclear calculations were made for critical experiments of a flux trap type reactor that neutron wise resembled the proposed High Flux Isotope Reactor. The purpose was to evaluate the adequacy of certain calculational models for use in HFIR studies. In general, … more

Preliminary Analysis of the HFIR Control Rods

Description: An analysis is made of the HFIR control concept in order to evolve a mechanical design for the control rods. Since the original design considered does not meet the objectives, the design is altered to include 1% holes in the white region and 2 to 4% holes in the grey region.

Fabrication and Inspection Procedures for Experimental Gas-Cooled Reactor Burst-Slug-Detection Tube and Thermocouple Penetrations

Description: Satisfactory methods were developed for penetrating the stainless steel burst-slag-detection tubes and stainless steel-clad thermocouples through the carbon steel pressure shell of the Experimental Gas-Cooled Reactor (EGCR). The burst-slug-detection system permits the positive identification of a channel containing a defective fuel element. while the thermocouples will be used to measure temperatures from numerous points within the reactor. Both types of penetrations require the welding of rela… more

Sheet Metal Can Furnace

Description: A need for a small vertical cylinder-type furnace arises frequently in the Chemistry Department at the Lawrence Radiation Laboratory (LRL). Adequate heat is the major requirement; close control or calibration is not usually necessary. A heating unit of this type can either be used for quickly concentrating solutions in centrifuge cones or, by the addition of a refractory pedestal--can be made into a crucible furnace for size 0 and 00 crucibles. Because much of the chemistry done at LRL is with … more

Fabricating Liquid-Hydrogen Targets From Mylar

Description: The increasing popularity of liquid-hydrogen targets in physics research has emphasized the need for containers with maximum beam transparency (i.e., thin walls and low Z) and suitable strength at cryogenic temperatures. Fabrication of a Mylar container satisfying these requirements is described here.

Calibration Of Bridgman Anvils, A Pressure Scale To 125 Kbars

Description: It is shown that a radial pressure gradient exists in the silver chloride when it is used as the pressure transmitting medium in Bridgman anvils. The gradient can be obviated by the use of circular sections of wire. The center of curvature of the wire hoop is made coincident with the anvil center. When the inner and outer diameters of the pyrophyllite retaining ring are 1/2 and 7/16" respectively, the pressure, P, is P = (0.725 + 0.468R) L where R is the fractional displacement from the center,… more

The Crystal Structure Of Cobalt Sulfate Hexahydrate

Description: Calorimetric measurements by Rao and Giauque (1960) showed some unaccountable residual entropy in crystals of [formula] at low temperatures. We have investigated the crystal structure in search of an explanation of the disorder. The resulting structure offers no possibility of disordered rings of hydrogen bonds such as were found in [formula], nor do we find any other explanation of the entropy discrepancy.

The Sideband Technique In A Variable Frequency NMR Spectrometer

Description: The purpose of this Note is to point out the advantages of the sideband technique over the derivative method in wideline NMR spectroscopy. In the sideband technique the absorption spectrum is recorded directly and the modulation amplitude is no longer a determining factor in the resolution.

A Pulsed Nanosecond Light Source

Description: A system for scintillations from nuclear events has been developed and is presently in use at the Lawrence Radiation Laboratory. This paper primarily describes the pulsed light source used to simulate nuclear events; it also describes the necessary nanosecond pulse techniques to measure the light source parameters and to operate large numbers of lamps. Considerations concerning distribution networks are shown. Use of the light source as a spark gap trigger is also discussed.

Remote Plastic Bag Passout Unit For High-Level Radiochemical Operations

Description: This system presents a method for making remote sealed-bag passouts from a multicurie-level chemistry processing enclosure. In addition, the polyethylene bags are changed remotely without exposing contaminated surfaces while always maintaining a low leak-rate seal. Our system employs an interchange box (the Passout Box) attached to the chemistry enclosure. Integrated with the box is a hydraulically operated jack that raises and lowers the bags, and a welder-cutter for sealing them. A single mas… more
