Reactor Plant Container Air Cooling System. Section III. Second Performance. Test Results DL-S-136 (T-550090)

Description: The purpose of this test was to determine the performance of the Reactor Plant Container Air Cooling System with four reactor coolant loops at operating temperature. Due to the fact that the test was performed with the chamber door open, no significant conclusion can be arrived at concerning the efficiency of the Air Cool System. The 1B supply fan circulated approximately 20 per cent less air than the 1A fan during the test. Later investigation revealed that the turning vanes above the 1B dampe… more

Thermoelectric Properties of the Plasma Diode

Description: It is well known that thermionic emission into vacuum is accompanied by a Peltier cooling of the vacuum metal interface. The interface may be thought of as a junction between two conductors: the metal, and an electron gas whose distribution is determined primarily by space charge. The addition of a small amount of easily ionized gas to the vacuum region does not affect the Peltier cooling of the interface, but is does squeeze the space charge region to about one micron and replaces most of the … more

A Study of Location Times for Positions Arranged on a Panel in a Random and an Ordered Manner

Description: The results of an experimental pilot study on the location time, for a sequence of N specified positions on a panel, are given for 1 <_ N <_ 30. The positions to be located were randomly arranged on one set of panels and arranged according to an ordering scheme on a second set of panels. Th location time for N positions randomly arranged on a panel varies approximately as N(2). In the case of an order arrangement the location time is essentially proportional to N. Even for as few as 30 position… more

Vapor Traps for Handling Liquid Sodium

Description: An active program is a present underway to develop equipment to handle liquid metals. Among the metals being studied are sodium and sodium--potassium alloy (the latter commonly referred to as NaK). In many of the systems being studied this liquid metal is pressurized by inert gas in the lines. At times it is necessary to bleed off some of this gas from the system. Although the gas is allowed to escape at a temperature at which the vapor pressure of sodium is extremely small, it has been found t… more

Foam Suppression of Radioactive Iodine and Particulates

Description: " A reliable, efficient and economical method is needed to remove radioactive halogens such as iodine and bromine and particulates from air in many atomic energy installations. One method we have developed which is particularly suited to reactor containment vessels or other large confined areas is foam containment. In this method an ether lauryl sulfate foam containing an iodine reactant is generated, rapidly filling the entire containment volume. This provides a tremendous surface area to w… more

Tests on a High Current R.F. Joint in Vacuum

Description: An R.F. joint tester was designed to determine the relative heating and tendency toward arching at high RF current density (100 amps/linear inch) of a 12 inch diameter circular copper butt joint in vacuum with several types of inserts and at various amounts of axial loading, ranging from a very small contact pressure to one of 1400 pounds per linear inch of joint.

The Biological Behavior of Organic Compounds Containing Radiophosphorus

Description: The study was undertaken with the objective of observing the distribution in the rat of organic compounds of phosphorus labelled with the P32 isotope as tracer. The fate of several of these compounds was studied in animals bearing tumors. The distribution of inorganic phosphate in animal tissues is well known but was included in this work for comparison with the organic phosphorus compounds.

Study of Metal-1.10-Phenanthroline Complex Equilibria by Potentiometric Measurement

Description: Technical report. From Abstract : "The silver-1,10-phenanthroline system has been studied and the stability constants determined for the 1:1 and 2:1 complexes using the silver electrode. This known system was then used to study the complexes of 1,10-phenanthroline with other metals. The log βn values found for the over-all stoichiometric stability constants are as follows: Ag, 5.02, 12.07; Mn, 3.88, 7.04, 10.11; Cd, 5.93, 10.52, 14.30; Zn, 6.83, 12.05, 16.92. The stoichiometric stability consta… more

Static Corrosion Tests of Fabrication Material for D-12 Waste Evaporator

Description: Three types of stainless steel (309 SCB, Carpenter 20, 304-L) were exposed to both the liquid and vapor phase of each of three types of solutions. The time of exposure totaled ten days during which the specimens were cleaned and weighed periodically. The three synthetic D-12 waste solutions contained respectively chrome-high chloride, chrome-low chloride and high chloride sans chromium. The solutions were renewed at each weighing.

Review of the Corrosion Product Radioactivity Program at the Army Package Power Reactor : Alco R & D report

Description: Abstract: An analysis and a summary are.given of the radioactivity buildup program at the Army Package Power Reactor during the last nine months. · Due to the wide fluctuation of water and crud results, only general interpretations can be made with this data. Metal test coupon data indicate a substantially greater buildup on Croloy 16-1 metal than on Type 304 stainless steel. Coupled with the decreased ability to remove the radioactivity buildup on Croloy 16-1 by conventional descaling techniq… more
