|
 | Coincident neutron detectors which can distinguish between neutrons occurring as a result of fission and those due to (alpha, n) or (Gamma, n) nuclear reactions have been described in a preceding report. The report discusses several methods of developing follow-on equipments with greater potential for the nondestructive assay of plutonium samples. The effect on equipment performance of the efficiency and neutron lifetime in the neutron detector and of analysis gate ... |

|
| Coincident neutron detectors have been developed which can distinguish between neutrons occurring as a result of fission and those due to (alpha,n) or (gamma,n) nuclear reactions. These detectors are described and several examples of their use are reported. Theoretical relations which predict count rates as a function of sample and equipment characteristics are developed. These permit the potential usefulness of coincidence measurements to be ascertained for any given set of ... |

|
| A summary is given of most aspects of reactor operations: operational data, pertinent information regarding maintenance and modifications to the facility, and services rendered during the period 1 January - 30 June 1968. The level of utilization of the reactor by in-house and outside users is discussed. Programs for which the reactor was used during the reporting period are also briefly described. (Author) |

|
| The radiations generated in a nuclear reactor are useful not only in nuclear physics research but also in many nonnuclear fields of science and technology. A review of present and potential applications of the NRL 1-MW reactor is undertaken with the purpose of encouraging additional utilization of this facility. Neutron activation analysis, a technique capable of assaying very small amounts of many of the chemical elements, is widely used, with ... |
