Activities in the experimental and analytical program for the production of /sup 238/Pu in light water reactors are summarized for the 1973 fiscal year. The activities included the irradiation of neptunium targets in the Connecticut Yankee reactor and the destructive examination of the irradiated target. Analytical and economic studies were also performed. (JWR)

Procedures for estimating the rate of air pollutant emissions from transportation systems are described. Emission factors and computation techniques for motor vehicles, railroad locomotives, aircraft, and waterborne vessels are presented. The major emphasis is on motor vehicle emission computations and data on model year emission rates, control device deterioration, and vehicle speed adjustments are given. Procedures for separating the cold start, computing evaporative emissions by source, and developing modewise emission factors are presented. TREFACT, a computer program designed to calculate motor vehicle emission factors, is described. Emission factors for diesel and electric railroad locomotives are presented and discussed. Aircraft emissions are descnibed in the context of total airport emissions. Emission factors for both inboardand outboard-powered waterborne vessels are presented. (auth)

Projects in support of the Aerospace Nuclear Safety Program are summarized. The objective of the program was to evaluate the radiological safety of SNAP systems and to develop methods and designs to assure that safety. Projects summarized are analyses and experiments for determining: (1) the disintegration of reactors reentering the atmosphere; (2) the burnup of fuel elements reentering the atmosphere, including ablation and dispersal of particles; (3) reactor criticality conditions and the assurance of subcriticality in water; (4) the behavior of reactors in transient power operation; (5) the nuclear behavior of reactors on impact with the earth and in handling accidents; (6) the assurance of shutdown at the end of the power production lifetime; (7) risks by various exposure modes from different methods of reactor disposal; and (8) thermophysical properties of SNAP fuel materials.

In contrast to earlier editions, which presented in compact form a summary of the complete store of the neutron data files, this edition aims to provide those portions of neutron data considered to be of prime importance and best suited for inclusion in ready reference form. This volume contains thermal cross sections, resonance properties, resonance parameters, and bibliography for nuclides from H to /sup 257/Fm. Notation and nomenclature, considerations involved in the recommendations, and a table of energyordered resonances are also included. (RWR)

A comprehensive survey of instrunnentation for environmental monitoring is being carried out by the Lawrence Berkeley Laboratory under a grant from the Natioral Science Foundation. Instruments being investigated are those useful for measurements of Air Quality, Water Quality, Radiation, and Biomedical Parameters related to environmental research and monitoring. Consideration is given to instruments and techniques presently in use and to those developed for other purposes but having possible applications to this work. The results of the survey are given as (a) descriptions of the physical and operating characteristics of available instruments, (b) critical comparisons among instrumentation methods, and (c) recommendations of promising methodology and development of new instrumentation. The survey material is compiled in 5 loose- leaf volumes which can be periodically updated. An update for volume 3 on radiation instrumentation is presented. New pages are included for insertion in the introductory material and also under the headings nuclear reactors, combination instruments, alpha particle instrumentation, beta particle instrumentation, x and gamma radiation monitoring instrumentation, gamma spectrometry, neutron monitoring instrumentation, personnel dosimetry, radionuclides (strontium -89 and -90, iodine -129 and -131, radium, uranium, plutonium, and instrument notes), and infrared.
