100 Areas technical activities report - physics, July 1951

Description: This is the monthly 100 areas technical activities report for the physics group for the month of July 1951. This group was concerned with pile related studies. Work discussed includes neutron attenuation measurements in pile shielding test facilities, studies of physical properties of shielding materials (concrete), work on a xenon generator and separation facility, further development and shielding work for a neutron spectrometer, continued work on a magnetic spectrometer, and counting equipme… more

Swelling and mechanical property changes in neutron-irradiated cold-rolled type 316 stainless steel

Description: Samples of cold-rolled Type 316 stainless steel were irradiated in EBR- II to a fluence of about 8 x 10$sup 26$ n/m$sup 2$ (E greater than 0.1 MeV) at 500 and 600$sup 0$C. Three sample configurations were used--small sheet tensile samples, small right-circular cylinders for immersion density, and thin foils for transmission-electron microscopy (TEM). TEM revealed voids in the foils irradiated at both temperatures. Immersion density results, however, indicated swelling only in the sample irradia… more

Status of uranium nitride development program at the Oak Ridge National Laboratory. Part II

Description: From RDT/SNS meeting on materials development for space reactor power systems; Washington, D. C. (23 Apr 1968). Declassified 26 Nov 1973. Information is included on encapsulated UN irradiation testing in the Materials Testing Reactor, results of post-irradiation evaluation of UN capsules, and irradiation testing of clad UN fuel pins in the Low Intensity Test Reactor and in the Oak Ridge Research Reactor.

Modeling and control of a multi-variable heat transfer process. [For heavy section steel irradiation]

Description: Methods of maintaining constant temperature in heavy section steel specimens during long-term reactor irradiation are described. Heat transfer models are discussed along with methods of steady state analysis and control strategy. The radiation experiment is to be conducted in the ORR Reactor. (JRD)

Study of calculated and measured time dependent delayed neutron yields. [TX, for calculating delayed neutron yields; MATINV, for matrix inversion; in FORTRAN for LSI-II minicomputer]

Description: Time-dependent delayed neutron emission is of interest in reactor design, reactor dynamics, and nuclear physics studies. The delayed neutrons from neutron-induced fission of /sup 232/U, /sup 237/Np, /sup 238/Pu, /sup 241/Am, /sup 242m/Am, /sup 245/Cm, and /sup 249/Cf were studied for the first time. The delayed neutron emission from /sup 232/Th, /sup 233/U, /sup 235/U, /sup 238/U, /sup 239/Pu, /sup 241/Pu, and /sup 242/Pu were measured as well. The data were used to develop an empirical express… more
