Modifications to Filling and Emptying System of Lock No. 1, Mississippi River, Minneapolis, Minnesota =: Hydraulic Model Investigation
From abstract: The existing locks at Locks and Dam No. 1 were constructed between 1929 and 1932. Problems have been experienced with accumulation of ice and debris at the intakes, air entrapment in the culverts of the filling and emptying system, excessive turbulence in the lock chamber during filling, and hazardous conditions downstream from the locks during emptying operations.

A Solution of the Distributional Error Problem in Cytophotometry
Use of that portion of the characteristic curve of photographic film in which transmission is linear with log exposure eliminates the distributional error and thus makes possible the assessment of total mass of an inhomogeneously distributed cell consistent without scanning or measuring the cell's projected area. Measurement consists of obtaining the difference in output of a photocell receiving the total light transmitted by a photomicrograph of the cell, and a photomicrograph of the microscope field illumination against which the cell was photographed. A method of making such measurements is given, and its basis is described.

Steady-State Recirculated Reactor Stability and Operational Characteristics - Water and Metal Temperature Coefficients
It is desirable that a reactor exhibit a self-regulating effect. If this were not true any disturbance to the reactor would result in a continual increase in the magnitude of the disturbance and the reactor would be unstable. In this investigation the reactor is considered to have two reactivity feed-backs: metal temperature and water temperature reactivity effects. These two variables through a metal temperature coefficient and water temperature coefficient determine not only the reactor stability but also determine many operational characteristics.

Kinetics of the Los Alamos Power Reactor Experiment (LAPRE)
A theoretical study of the kinetics of a model of the Los Alamos Power Reactor Experiment (LAPRE) was made through integration of the dynamic equations with the IBM 701 computer. The stability is investigated under various conditions of power demand, rod-induced reactivity changes, and other conditions especially applicable to LAPRE. The results are given in graphical form, along with conclusions as to appropriate conditions of operation.

Regeneration of Silver Reactors
A study of the variables involved in regeneration was undertaken to determine means of improving the regeneration efficiency and increasing the useful life of a reactor. Information gained from regeneration studies on a 4-inch-diameter by 8-foot-high column indicates that the present regeneration procedure is optimum as to quantity, concentration, and rate of addition of regenerant solution. It appears feasible to restore a plugged reactor by washing off all the silver nitrate from the packing and recoating by a normal regeneration cycle. Such a procedure could be utilized only if there is sufficient dead space in the bottom of the reactor to hold the wash solution.

LRL-Nevada Drill Hole Survey Technique
The demands of the scientific programs of the Lawrence Radiation Laboratory at the Nevada Test Site have necessitated the development of special drill hole survey techniques. These techniques, in general, have made possible the attainment of greater survey accuracies than are ordinarily obtained by the drilling industry in the course of normal survey work. For drill holes requiring a moderately high degree of location accuracy, standard survey equipment, manufactured by Eastman Oil Well Survey Company was adapted by LRL to meet this need. Where an extremely high degree of survey accuracy and control of drilling effort is necessary, such as in the drilling and survey of line-of-sight holes, special optical equipment was developed. The modifications of equipment, refinements in procedures, and special techniques necessary to adapt this equipment to meet the more demanding accuracy requirements of scientific programs are discussed. The overall techniques of survey, equipment used, and the accuracies obtained together with results of completed surveys showing a comparison with standard land survey methods are also discussed and illustrated in some detail.

Comments on Equipment for a PRTR Water Quality Control Laboratory
This document describes required laboratory space and lists major equipment items necessary for a routine water quality laboratory in the P. R. T. R. Building. During discussions with R. D. Widrig and V. L. Rooney about the analytical sample program for the Plutonium Recycle Test Reactor, the author was asked to summarize equipment and space needs for a water control laboratory to provide routine analytical coverage on some of the water systems. Based upon 1706-KE-KER experience, some operating personnel may be used to provide analytical coverage on those routine analyses that are needed on around-the-clock basis with a savings of both time and money.

Relative Biological Hazards of Radiations Expected in Homogeneous Reactors TBR and HPR
An evaluation of the relative health hazards of radioisotopes produced in nuclear reactors is reported. The most important hazards were indicated to be I131, the Sr90 - Y90 chain, the Ce144 -Pr144 chain, Sr 89, the Ba140-La40 chain, Y91, the Zr95-Nb95 chain, Pr143, La140 , and Pa233. The most critical body organs affected by air-borne contamination are the thyroid gland, the bone marrow, the lungs, and the gastrointestinal tract. Where possible, continuous daily removal of gaseous and solid fission products from the reactor environment can be shown to permit very significant reductions in the total hazards. Homogeneous reactors, such as the Thermal Breeder Reactor and the Homogeneous Plutonium Producer Reactor, specifically studied in this report, are designed with daily removal cycles and may be considered potentially safer than heterogeneous reactors.

Poisoning and Production in a Power Plant
The yield of 49, the efficiency of production of 49, and poisoning in a power plant are discussed. Only the crudest of estimates of the poisoning are possible: these indicated that production will probably not be hampered by poisoning. In this case the yield of 49 could be as high as 3 kg/ton but only about 2 kg/ton is compatible with a fairly high efficiency. In the case that production is stopped by poisoning, smaller yields, proportional to the tolerable loss in k, are obtained. In this case the yield will be improved by a factor of 2 or 3 if only the most poisoned parts are extracted and replaced by new uranium.

Technical Concept-Operation Bren
From Abstract: "The Oak Ridge National Laboratory (ORNL) Health Physics Research Reactor is to be attached to a hoist platform on a 1500-ft tower at the Nevada Test Site (NTS). The project is a continuation of the studies commenced in 1956 for evaluating the radiation doses of persons exposed to nuclear weapons, especially the residents of Hiroshima and Nagaski, Japan. Measurements will be made of the energy, angular, and spatial distributions of the radiation from the reactor."

Closed Extensions of the Laplace Operator Determined by a General Class of Boundary Conditions
This paper is concerned with the spectral theory of closed operators in Hilbert space determined by the Laplace operator and certain general boundary conditions. Using the method of J.W. Calkin, we treat the case of a bounded domain in E(m) with C(1,1) boundary, and, in addition, extend the method to cover the case for which the operator L in the boundary condition is not necessarily self-adjoint. It is shown that there exists an appropriate linear close of functions [formula] such that the operator in the Hilbert space [formula] and [formula] is self-adjoint. In potential theoretic terms it is the set of all sums p + h, where p is the potential due to a charge g in G and h is the potential due to a surface charge f on ∂G and h is a potential due to a surface charge f on G, where g and f are, respectively, square integrable over G and ∂G

Thermal-Neutron Flux at the HRE-2 Core Wall, Determined from Zircaloy-2 Induced-Activity Measurements During Runs 13, 14, 16, 17, 18, 19, 20 and 21.
The thermal-neutron flux prevailing near the upper hole in the HRE-2 core wall was determined from measurements of the induced activity in a specimen cut from the edge of the hole. The specimen was removed following run 21 and was thus exposed to reactor neutrons during runs 13, 14, 16,17, 18. 19, 20, and 21. The neutron flux, calculated for an average core power level of 2 Mw, was 2.8 x10^13 neutrons/cm^2 sec. the core wall area from which the specimen was removed was located approximately 16-in. from the core center.
