The operation of the Fast Reactor is considered in terms of normal equilibrium conditions and normal shut-down. The proposed loading, control rod adjustment and subsequent "floating" operation are discussed. Safety devices and interlocks are described. Temperature and reactivity changes are examined with respect to various system failures, phase changes, and "flashing" of the reactor. Slow changes due to faulty slug cooling are also considered. The calculations were initially based upon 10 kw operation. Performance tests of the mercury system now indicate that 20-kw operation may be feasible.

The following report describes the high pressure and temperature homogeneous reactor experiment which has been started at Los Alamos, as well as the hazards and safety aspects for the experiments.

The following report describes the findings of air samplings taken that followed the Wasp detonation of Operation Teapot.

Abstract: This document is a survey analysis of soil samples from Los Alamos, Pueblo, Bayo, and Mortandad canyons to determine the presence and activities of radioactive contaminants. Also included are the results of analyses of a few samples of grass and of surface water. This survey covers the period from spring 1953 to spring 1955.

Abstract: "A description of the instrumentation for neutron flux measurement from Kiwi-A at NTS is given as some discussion of start-up considerations, detector design, system response adjustments, and power calibration of the reactor at some low level of power."

Preface: This report contains data and information on the resurvey effort and the effect of residual contamination as a result of nuclear weapons development programs conducted in this area.

As part of the LASL portion of the US EROA NURE program, water samples from 534 locations and sediment samples from 2936 locations were taken over a 7770 square kilometers area of the Estancia Valley in 1975 and analyzed for uranium.

This is the second part of a report of a uranium hydrogeochemical and stream sediment pilot survey of areas of New Mexico.

A report discussing the Hydrogeochemical and Stream Sediment Reconnaissance conducted for uranium un the Socorro NTMS Quadrangle

A report describing the results of a detailed hydrogeochemical survey directed by the Los Alamos Scientific Laboratory of well waters in parts of the Saint Johns and Socorro Quadrangles.

This report discusses uranium findings from a reconnaissance of the Gallup NTMS quadrangle through water, sediment, and water samples collected from streams, springs, and wells.

Report of reconnaissance of the Albuquerque NTMS quadrangle through water and sediment samples collected from springs, wells, and streams. Samples analyzed for uranium and 42 other elements. This report is limited to samples containing uranium concentrations greater than the arbitrary anomaly thresholds of 5 parts per billion for waters and 6 parts per million for sediments.

From introduction: This report describes work done in the Tularosa, New Mexico, National Topographic Map Series (NTMS) quadrangle (1:250 000 scale) by the Los Alamos Scientific Laboratory (LASL) as part of the nationwide Hydrogeochemical and Stream Sediment Reconnaissance (HSSR).

From summary: This report describes work done in the Douglas, Silver City, Clifton, and Saint Johns, New Mexico/Arizona, National Topographic Map Series (NTMS) quadrangles (1:250 000 scale) by the Los Alamos Scientific Laboratory (LASL) as part of the nationwide Hydrogeochemical and Stream Sediment Reconnaissance (HSSR).

From introduction: This report presents uranium and other elemental data resulting from the Hydrogeochemical and Stream Sediment Reconnaissance (HSSR) of the Shiprock National Topographic Map Series (NTMS) quadrangle, New Mexico/Arizona, by the Los Alamos Scientific Laboratory (LASL).

From summary: This report contains data collected during a geochemical survey for uranium in the St. Johns National Topographic Map Series (NTMS) quadrangle of Arizona/New Mexico (Fig. 1) by the Los Alamos Scientific Laboratory (LASL) as part of the nationwide Hydrogeochemical and Stream Sediment Reconnaissance (HSSR).

Notes Based on a set of five lectures given by R. Serber during the first two weeks of April 1943, as an "indoctrination course" in connection with the starting of the Los Alamos project.
