ABSTRAM The authors made experiments trying to speed up the gravity method of detecting silicon in ferrosilicon by decomposing a small batch of finely ground material in a 50-percent solution of alkali and making a photocolorimetric analysis of the yellow coloring of the silicon-molybden complex. An iron crucible was used instead of a silver one for the decomposition and the silicon-molywemn blue was photocolorimetrized on a FEK-H pbotocolorimeter. Seventeen specimens of high-percentage and three of medim-percentage ferrosilicon were analyzed and respective tables are presented of the results. These tables give the percentages of silicon as shown by, the colorimetric and gravity methods of analysis.

In-ta, 1955, 5-6, 338-3116 Abstract : Me stomach content of dogs was collected through a fistu- la every 15 minutes. The total acidity, free, and bound acidity were determined. The fluctuation of the electro- potential (E) of the mucous membrane of the stomach and its motility was registered photographically throughout the procedure. The registering of the electrical flow from the stomach was clone with the aid of a mirror gELlva- nometer. The movements of the stomach were recorded by a method of air transmission. Morphine (1) and heroin (II) in doses 0.02-0.05 mE./kg did not produce secretion Card 1/3 20 Usm/Pharmacology. Pharmacognosy. Toxicology - Analgesics.

I in 0-075-0-2 mg/kg doses and II in 0.075-0.1 mg/kg produced in 2-3 hours a lowering of E; its fluctuation increased and took on a rhythmic character. The period-i- city of E fluctuations and stomach contractions was dis- turbed. A delayed stomach secretion was noted. I in do- ses of 0.5-1 mg/kg, and II in doses of 0.3-0.5 wWkF, changed the periodicity of E as well as the stomach con- tractions. A considerable lowering of E and the presence of small fluctuations was noted. The stonach secretionB were observed for 10-65 minutes. The author notes that the lowering of E preceeded the appearance of free HC1. There was no strict proportionality between the stomach acidity and its electrical activity. I in doses of 10- 20 mg/kg and I-T in 5-10 m&/kg produced a prolonged inhi- bition in secretion and with it the rise in E. Thus, Care- 2/3 - PI - n I A C,'/' /< OVA)-) 7- -Z _. USSR/11harmacology.

June-1956) was attended by about 2000 technicians and scientists of 24-countries. The Soviet delegation was under the leadership of the deputy minister for electric power Plantsp A.S.PAVLENKO. Two sectional conferences were devoted to the problems of at6mic energetics. Numerous lectures dealt with atomic power plants both planned and"under construction, and further lectures dealt with the following problems: The general description of the de- velopment programs of atomic energy in various countries, the evaluation of atomic power plants from the point of view of economy compared to other energy sources, the removal of radioactive residues. The lecture delivered by the Soviet delegation dealt with the positive experience gathered in the course of two years Of operation of the first nuclear elec- tricity works and on the basic features of the development of atomic energetics in the USSR. In this connection above all-the program of necessary work to be performed in connection withkthe-equipment of industrial atomic power plants attracted attention. In the course of some lectures delivered by members of the Soviet delegation several problems connected with the economy and the technology of atomic energy were investigated.

For some processes tha vo%.,r coefficient of reactivity may be subdivided Anto an instantaneous power coefficient p and a retarded power coefficient k with the average retardation time T. Such a treatment is suited alp.~~ for reactors Yrith neutrons having medium and thermal energies. The coefficients p and k may be both positive and negative. The authors investigated the behavior of a reactor, which is connected only with the above-mentioned temperature effects. Card 1/4 The neutrons were subdivided into two groups: instantaneous The Behavior of a Reactor With Tempexi0mire; Auto- 'SOV/89-7-4-7/28 replation neutrons (with the life-time zero) and retarded neutrons (with the life-time r ). When the reactor is stopped, the 0 contribution of the retarded power effect decreases exponant!aiv with time.

The surroundings of x the first singular point determine the character of the increase of reactor power from zero onwards, and the second singulax- point determines t1n behavior of the reactor in the power range near the steady power. In the neighborhood of the steady point the solutions of the above equation are more manifold; There are aperiodically steady and aperipdically non- steady, oscillation-stable and osoillation-unstable solutions. In,addition, there is a special type of stable solutions. The ranges within which the solutions enilmerated exist are shown by a diagram.

Ito most distinguishing feature is the very small contribu- tion (,vio-4) of the delayed neutrons in its normal operationt it is about Card 1/1 A pulsed fast reactor one hundredth of that of the usual steady uranium reactor. Th%l pulses appear because whenever the reactor becomes overcritical a burst of prompt neutrons results. The half width of those pulses is 36 gsec. The frequency with which the pulses are repeated can be varied between 0 and 80 pullies/seo. 'Fig. 2 shows the construction of this reactor. The periodic change in the reactivity Is brought about by the displacement of 22873 5/069/61/010/005/001/015 B102/B214 the two U235 blocks placed in two disks that can be rotated. The main block in pressed in the form of a disk, 1100 mm in diameter, and can be rotated with a peripheral velocity of 276 M/sec (at 6000 rpm) during which it peeves through the core center. The reactivity change obtainable from the motion of the main block is 7.4 %, that obtainable from the motion of the auziliary block is 0.4 %. The stationary part of the core consists of plutonium lumps in steel jackets. The reactor is started by a rough regulator, In this case.a movable part of the reflector. It gives a reactivity change at the rate of 13-10-5 -1.3-10-5 800- 1. The manually operated rol is also a part of the reflector. Two plutonium rode in electromagnetic suspension serve as soram. They can be separated from the core with an acceleration of 20 g. Their separation causes a reactivity Card 2/7,?( 22A73 B/oLig/61/010/005/001/015 A pulsed fast reactor B102/D214 decrease of 2-1.1 ~; the rough regulator allows a reactivity change of 2.4 %, the-,manual regulator 0.1 %, and the automatic regulator 0.036 %. The reactor possesses also a reactivity booster for the produotion,of one intensive pulse. The control and shield system is an automatically functioning electronic arrangement with BF counters and ionization 3 chambers. The whole reactor is placed in a room of size 10-10-7 m whose concrete walls allow complete protection from radiation. The most, impirtant experimental arrangement consists of a 1000 m long neutron couductor, a metal tube, 400 mm in diameter in the first part and 000 mm In the second part ir. which a pressure of 0.1 mm Ng Is maintained. This conductor connects a chain of Booalled "intermediate pavilion "" ( at distances of 70$ 250, 500, 750, and 1000 m from the reactor) in which experiments can be carried out. There In also an additional neutron conductor of 100 m length. The reactor chamber is joined to an experi- mental chamber in which four neutron beame of up to 800 mm diameter are available. There uj such an experimental chamber also above the reactor chamber. Various experiments were carried out with the reactor and they are described in the present paper..

TITLE: The future of fast reactors PERIODICALt Atomnaya energiyat v. 11, no. 4, 1961; 370 - 378 TEXT: The obtaining of a higher conversion ratio; which is only possible with fast reactors, involves serious technical difficulties. One of the main problems is to find a good coolant, At present, sodium is the best of those produced and used on an industrial scale, Economic problems are, however, still unsolved. Since with a reactor of a given power the greater the energy intensity the smaller its size, fuel, enrichment should be as high as possible. This requirement causes cooling problems and raises the cost of chemical reprocessing. These disadvantages can be reduced by increasing the burn-Lip fraction. The production of suitable fuel elements for this purpose presents a further problem. In the USSR these matters are sadied on the research engineering reactor ~P-5 (BR-5) (coolantt Na, maximum thermal Powers 5000 kw, fast neutron,.fluxt 1015 n/cm2.sec) for the industrial development of fast reactors. This Card 1/4 1; The future of fast reactors 27524 S/089/61/011/0C4/005/008 B102/B138 reactor is designed for the sbady ofj (1) heat transfer problems with radioactive sodium as coolant$ (2) testa of specimens and prototype fuel elements, (3) the kinetics of fast reactors with high energy intensity, (4) materials under fast neutron fluxes and nuclear physics unaer these conditions. Plutonium oxide as a fuel hag shown several advantages com- pared with metallic plutonium. The reactor core consists of 80 rod assemblies (stainless steel tubes filled with PuO 2) , additional assemblies of rods of natural uranium and special assemblies with various samples exposed to fast neutron irradiation. The core itself has a cylindrical shape (280 mm. high, 280 mm wide). Kickel was chosen as the reflector material. The maximum heat of 220 kw liberated in the reflector was carried off by forced draft air. The core was cooled by sodium flowing at a maximum speed of 5 m/sec (outlet temperature "5000C); in the second circuit, a eutectic fusion Na+K was used. In both circuits a total quantity of N5 m3 of liquid metal circulated at & rate of 250 m3/hr (circulation period 430 sec). one loop of the second circuit was cooled by air, the other incorporated a steam generator. The reactor was started in summer of 1958 (without coolant); in January 1959, th6 critical state Card 2/4 27524 S/089/61/011/04/005/008 The future of fast reactors B102/BI38 in the sodium--filled system was attained. Operation commenced in the summer of 1939 (maximum power 5000 kw). Sodium proved to be a very good coolant, better than the Na-K alloy. Vith the aid of cold tra s the oxide concentration in the coolant could be kept atr4(1-5) .10 3~. By June 1961, a maximum burn-up fraction of more than 47'~ was reached. The integral fast-neutron flux exceeded 2-1022 n/cm2 at that time. No Pu impurities were detected in the cooling system. The advantages of the ceramic fuel (oxide) were confirmed. Stability and safety tests were also made. All experiments indicate thatthe first future task will be to solve the question of costs in cooperation with industry. The perform- ance of the BR-5 reactor was nearly the same as that of a power reactor. The most important parameters of the BR-5 reactor are compared rith those of a 750-Mw fast reactort Energy intensity 360 (600) kw '/liter; coolant temperature at the outlet from the reactor: 500 (550) OC; burn-up frac- tion,'N4 Ctu5) %.

Inside the core the neutrons have energica of more than 100 key which they lose almost ctmplo tely in passage through reflector and shield. Iv the outer layers of the shield, their mean energy does not exceed some tons of ov. In the key range (E,>50 key) spectra were measured for the most important beams and channela. For the other cases, they were determined from threshold reactions. The soft part of the spectrum within the reflector was determined from the spatial distribution of neutrons with Z --t5 ev, recorded with gold renonance indi- n oators. The total neutrop fliAx was determined only at the points where the Pu239 fission cross section was constant. Direct neutron spectrim mcasur6ments were carried out in a vertical (OK-70) and a horizontal (B-3) channel using (Ho3+Ar)-filled ionization ohamber in the first case and the neutron tiantmissionmethod with n-hexane in the second.

TITLE: New method of characterizing the structure of polyacryl nitrfle fiber PERIODICAL: Xhimicheskiye volokna, no. 1, 1961, 22-24 TEXT: A rapid laboratory method has been worked out for determining the structure of polyacryl nitrile fiber (P4, i.e., the presence of micropores, loose sites, and other inhomogeneities which affect the behavior of the fiber during treatment and dyeing. Laboratory tests have hitherto been made by simulating the manufacturing process. As the number of inhomogeneities has an effect on diffusion, calorimetric measurement of the amount of heat liberated by PAN swelling in dimethyl formamide within the first five min- utes has been suggested. A figure shows that the liberation of heat (0-4-7.2 cal/g after 1 minj 0.7-8-7 cal/g after 2 minj 1.8-13.7 cal/'g after 5 min) depends on the method of PAN synthesis and its preliminary treatmentj The liberated heat approachesequilibrium-, Qo . 12.5 cal/g (determined in an adiabatic calorimeter).

In ad- dition, the structural density was determined from the specific gravity. Freshly precipitated PAN fiber had a specific gravity of 1.626, which wast/ increased to 1-794 by drawing and oiling. Treatment with water reduced the specific gravity, whereby the micropores were enlarged and new ones were formed. There are 1 figure, 2 tables, and 12 Soviet-bloc references.

The capacitors are provided with a shunting circuit breaker intended for operational switching and for disconnecting the installation for repair or examination. The operating conditions of these circuit breakers have certain special features. The class of insulation can be lower than that of the rest of the system if the breakers are installed on an insulated platform. The rupturing capacity is not very great as the-greatest current to be: disconnected is the line current in normal overload conditions with a low -rate of rise of restriking voltaVe because of the large capacitance in parallel with the contacts.

Contamination of the oil was insignificant at currents up to 450 A. This contamination can be reduced by increasing the speed of separation of the contacts and increasing the damping resist64ices in the breaker circuits. It would be advisable to develop circuit breakers of light constraction speciall.y intended for opeiation in series capacitor install- ations. Circuit breaker BM-35 cannot be used without recon- struction of its contact system. There are 7 figires and 3 references.
