Rural Populations in Congressional Districts

Description: This report analyzes rural populations in congressional districts using data from the 1970 census, where a rural area is defined as a town or village of less than 10,000 people. Towns or villages with a population of less than 25,000 and 50,000 are considered as well.

Recommendations for Shape of Earthquake Response Spectra

Description: From summary: The major objectives of the studies described in this report were to analyse and evaluate a number of significant earthquake records and to utilize the results to develop "standardized" design spectrum shapes to be used in the seismic design of nuclear power plant facilities.

Evaluation of ex-reactor loading event on high-fluence EBR-II control-rod thimble 5E3

Description: A Type 304 stainless steel EBR-II control-rod thimble (CRT 5E3) with high fluence was damaged while undergoing dimensional evaluation. The damage, which occurred when the thimble was inadvertently loaded in a bending mode, consisted of rather localized but extensive fracture. An elastic stress analysis of the bending mode was done on the thimble, using semimembrane shell theory. The analysis disclosed several important aspects that the simpler and more commonly employed techniques do not disclo… more

Study of Signal Shaping and Energy Repsonse of Large NaI(Tl) Spectrometers for Application at NAL

Description: Signal shaping properties are demonstrated with a large NaI(Tl) crystal assembly, 20 in. thick and 30 in. in diameter. Correlated energy resolution responses are shown for total energy absorption in the crystal from 580 MeV electrons. Light collection optics by diffuse reflection most likely determined the 10% to 90% rise-time of signals of 80 nsec, connected with the transit time of trapped light, before it reaches a photocathode surface. Using a signal clipping technique, the trailing edge of… more
