COMPARISON OF BULK SHIELDING REACTOR CENTERLINE MEASUREMENTS IN WATER WITH PREDICTIONS

Description: Measurements of fast neutron and gamma ray dose rates in water along the centerline of the Bulk Shielding Reactor (BSR) are compared with predictions made by use of three available computer programs. It is found that the predictions are very dependent on the assumptions made concerning power distribution and that the more accurate descriptions of the source lead to predictions that agree with measurements to within 20% throughout thickness ranges as great as 100 centimeters of water.

Removal site evaluation report on the bulk shielding facility at Oak Ridge National Laboratory, Oak Ridge, Tennessee

Description: This removal site evaluation report on the Bulk Shielding Facility (BSF) at Oak Ridge National Laboratory was prepared to provide the Environmental Restoration Program with information necessary to evaluate whether hazardous and/or radiological contaminants in and around BSF buildings pose a substantial risk to human health or the environment (i.e., a high probability of adverse effects) and whether remedial site evaluations or removal actions are, therefore, required. A removal site evaluation… more

Neutronics model of the bulk shielding reactor (BSR): validation by comparison of calculations with the experimental measurements

Description: A neutronics model for the Oak Ridge National Laboratory Bulk Shielding Reactor (ORNL-SAR) was developed and verified by experimental measurements. A cross-section library was generated from the 218 group Master Library using the AMPX Block Code system. A series of one-, two-, and three-dimensional neutronics calculations were performed utilizing both transport and diffusion theory. Spectral comparison was made with /sup 58/Ni(n,p) reaction. The results of the comparison between the calculation… more

Critical Experiments With Arrays of Orr and Bsr Fuel Elements

Description: Critical experiments were performed with ORR and BSR fuel elements to determine safe arrays in which the elements could be handled and stored. The data indicate that the optimum spacing for criticality of 168-g ORR elements in water is 0.2 in. between locating bosses annd that an infinite array of vertically placed elements onc element high would probably be subcritical with a 1 1/2-in. spacing between locating bosses. For uniform arrays of adjacent elements in water, variation in thc fuel load… more

CALCULATED REACTIVITY CHANGES PRODUCED BY THE OSCILLATION OF AN EPITHERMAL NEUTRON ABSORBER IN THE BULK SHIELDING REACTOR

Description: An attempt is made to ascertain the optimum working conditions of a pile oscillator and to compare this method with the danger coefficient technique from the point of view of minimum amount of resonance absorption which can be detected. The space-time behavior of the absorption properties of the sample is described by means of a delta -function and the reactor kinetic equations are obtained by using a single mode expansion of the flux. The results are applied to a bare reactor model equivalent … more
