Test Results

Description: "The determination of the changes in radiation level in the hairpin loops resulting from continued operation of the reactor at power were studied. The results indicate that the radiation level in the hairpin loop resulting from continued operation of the reactor at power decays to a relatively low level approximately 20 minutes after isolation of the loop."

Test Results

Description: "The purpose of this test is to determine that the system operating pressure is sufficient to meet system design requirements and also to check if leakage occurs through the hydraulic pilot valves. All main hydraulic stop valves operated within the prescribed time limits. Leakage from the system could not be determined because of the unavailability of a proper range test gage at the time the test was performed. The alignment check of the three-way selector valves was not performed because of in… more

The Determination of Trace Elements by Neutron Radioactivation Analysis

Description: Nuclear science has created a new analytical procedure for the determination of trace quantities of many elements. This procedure, called "radioactivation analysis," is a method in which nuclear reactions in a chain-reacting pile (or an accelerator) produce an artificially radioactive isotope of the element being determined. This radioisotope has its own characteristic radiations and mode of decay. Activation analysis is unique because (1) it has great sensitivity of detection for most elements… more

Some Calculations for the Boiling Reactor Shield

Description: The shield for the boiling reactor experiment is intended to serve for a series of homogeneous reactors. With this in mind the layout shown has been designed to provide flexibility. In order to obtain information on required shield thicknesses some calculations have been made for the first two proposed reactors, the Teapot and a six foot boiling reactor. Calculations include the radiation from the reactor compartment into the instrument room and through the top shield during operation. In the c… more

Design Data for ISHR (Second Edition)

Description: The following design data sheets are for the main circulating system for the ISBR. The data presented are for an intermediate scale, two region, homogeneous converter for production of U233. The data is based on an overall gross power rating of 60MW. These sheets will be supplemented and corrected as more information becomes available. It is requested that recipients of this memo examine the data with which they are concerned and report inaccuracies so corrections can be made in subsequent edit… more

Station Radiation Level Survey. Section II. Fifth Performance. Core I, Seed 1. Test Results DL-S-157

Description: The purpose of the test was to determine the level of the radiation field in the Turbine Plant during a significant power run. The initial power level survey had an average radiation level of 0.02 mr/hr. this survey showed and average radiation level of 0.03, which was considered background level. this radiation level was far below the maximum allowable level of 2 mr/hyr. No Neutrons were detected.

Effect of Core Corrosion Sample Assembly on HRT Critical Concentration

Description: An estimate has been made of the critical fuel concentration in the HRT, taking into account the effect of the core corrosion sample assembly. The estimate is based on a number of previous calculations of critical concentration in an un-poisoned reactor and one calculation of critical concentration as a function of poison level. The makeup of the first core corrosion sample assembly was used in calculating equivalent neutron poisoning effects. Figure 1 shows the estimated critical concentration… more
