A Transistorized Pulse Height Analyzer for Gamma Spectroscopy

Description: From abstract: "A scintillation detector has a pulse height output which is a linear function of the energy of impinging gamma radiation. A pulse height analyzer system determines the amplitude distribution of this train of pulses. The system also displays this information graphically in a form which is convenient for further analysis."

Determination of Chemical Characteristics of the 1B Boiler. Section II. Test Results DL-S-209.

Description: The purpose of the test was to determine the extent of mixing when chemicals are added to an idle boiler. The conclusion was that the chemicals added to the 1B boiler in a hot, idle condition did not become evident in any of three sampling locations tested within a period of two hours after the chemical injection. It is concluded that circulation in idle boilers is inadequate to promote the mixing necessary to distribute chemicals throughout the unit in a two hour period.

Polarography in Organic Analysis

Description: The discussion attempts to summarize present trends and future possibilities. After consideration of the areas of analytical applicability of polarography of organic compounds with stress on the use of chemical treatment to convert polarographically inert species to active ones, the importance of the composition of the test solution is discussed from the viewpoint of the effects of pH, buffer composition and concentration, ionic strength, solvent nature and additives. The critical factors in th… more

Calculation of the G Factor for Gas Scattering Experiments

Description: The "G factor'' relating the yield to the beam intensity, target density, and scattering cross section is calculated for several types of aperture boundaries. The case of a front aperture composed of two parallel edges of infinite height with a rear aperture of any shape is calculated up to terms in the fourth derivative of the cross section. (W.D.M.)

Initial Start-Up and Low Power Operation. Test Results DL-S-161 (T-550127). Special Procedure Section 1

Description: The purpose of the test was to determine the Reactor Plant Systems operating characteristics during start-up and in the low power range. The Decay Heat Removal Valve, instead of operating for one hour as called for in the Test Procedure, operated for only six minutes. This was due to the fact that the turbine room basement became filled with steam when the Decay Heat Removal Valve opened. Due to the fact that the valve operated only once, the data therefore includes information for only one loa… more

Reactor Coolant Loop Outage Test. Section I. Second Performance. Test Results DL-S-170 (T-554928-A)

Description: The purpose of this test was to determine the temperature transient experiences as a result of the loss of an operating loop during power operations when the main coolant hydraulic stop valves remain open. Also to determine the effectiveness of the operating procedure for removing a loop from service when the reactor is critical. The conclusions were the temperature transients experienced in the 1C loop as a result of keeping the hydraulic valves open after the 1C Main Coolant pump had been sto… more

Governor Performance Tests. Section IV. Second Performance. Test Results DL-S-174

Description: The purpose of this test was to determine the load at which each of the governor valves opens with a primary plant T(avg) of 500 F. Conclusions: It was found that the No. 2 valve opened at a generator load of 16.6 mw, the No. 3 valve opened at a generator load of 33.6 mw and the No. 4 valve opened at a generator load of 48.4 mw.

Flow Distribution Across the Core. Test Results DL-S-182 (T-550097). Section II

Description: The purpose of the test was to determine the flow mixing characteristics of the lower plenum. Conclusion: Mixing appears to be quite small. The temperature indicated by the thermocouple nearest the cold loop decreased approximately 15 F. The cold loop temperature was 15 below the initial reactor coolant average temperature when the cold loop was places in services. The thermocouple furthest from the cold loop showed little or no change in temperature. The rate of change of reactor coolant tempe… more

Technical Report No. 6

Description: The original melting apparatus has been converted from a one-zone to a six zone operation. Another one-zone refiner has been constructed. The experiments that have been performed to date with these two refiners are discussed in the firs two sections of this report. It is pointed out that it appears that zone melting has a limited application for the refinement of KCl and KBr. We are exploring two other means of purification: 1) ion exchange, and 2) distillation. Work on the analysis of the salt… more
