In general the metals became stronger, with reduced elongation, area reduction, and impact strength, but Increased microhardness. The effect on aluminum was different, because the tempeaature is above the aluminum recrystallization temperature. Grain size was increased during irradiation. Although the material propertie usually changed in a way that is usually associated with cold working, the changes are in fact quate different: the larger grains showed neither slip lines nor twinning; nor was strength decreased as would be anticipated from the larger grain size. Zirconium similarly irradiated showed increase in strength and electrical resistivity. Grain size increased, but with some twinning and recrystallization. Various austenitic steels showed the same changes as iron, due to irradiation; no tendency to change to ferritic steel vas observed, if plastic deformation was avoided.

This paper describes briefly some of the properties of metallic plutonium. Given here is a thermographic re- cording of six plutonium phases and the magnetic susceptibility curve in the function of temperature. The equilibrium plutonium-beryllium diagram is described. There is one intermetallic compound PuBell., of a cubic lattice with a = 10.253t 0.002 M which melts above temperature of 595oC, ts composition being close t;* pure plutoniumplem There are two intermetallic compounds in the plutonium-lead system. The first forms in the region between 30 and 50% (at) Fb. The womposition of the second is PuFb3. The latter is of crystalline structure: cubic Cu3Au type, a : 4.80 kX. The melting point of first com- pound is 9500CY and of the second, 8150C. Three eutecticzs exist: the first is between plutonium and the first compound at 6100C and the second, at 8000C with an approximate 70% (at) Pb composition. Several equalibrium diagrams of plutonium with metals of the fonrth period (transitional elements) of the Wndeleyev Table (V, Cr, Mn. Fe, Ni) are givenam in this report. The equilibrium diagrams of plutonium with vanadium and chromium are similar to each other and are of the simple eutectic type. metallic compounds are absent in the a" oys. The melting points of the eutectics are 6250C (vanadium alloy) and 615 0C (chromium alloy). One metallic compound PuMn2 exists in plutonium-manganese alloys. -It has a cubic lattice of the %~% type with a - 7.27 M and a narrow solubility region ( 3%) Plutonium is soluble in Mn in small amounts. Two eutectic reactions occur; the first at 2.3% ~!n and 5100C and the second at 50% 14a and 10000C. The density and microhardness of a number of alloys have been measured. ITHOSEYEMKIY, S.T.

A beam of x-rays is incident on a flat specimen. The diffraction ray, passing through the entrance s3it, is reflected by a monochromator and is re- corded with a counter. The kin~atic setup permits automatic recording of the x-ray pattern with a potentiometer over a range of Vallf-Bragg angles from 00 to 450, or else to plot the diffraction lines from the number of pulses counted by a mechanical counter. Lead shields 90 em thick protect the countef from the radioactive radiation of the specimen. The monochromator used was a rock salt crystal, bent plastically by Johann's method. If the specimen is highly active it is possible to use a second order reflection from the monochromator, thus resulting in an Increase of the sheilding.

One of the principal limitations of modern high accuracy crystal analysis is uncertainty in the atomic scattering factors. Because of the occurrence of forbidden reflections in diamond it has long been known that anisotropic correction should be made to the scattering factors. The density of elqctrons in an atom is expressed as R(r)~ (9,0 electrons/cmi where R depends only on the radius a d y is a characteristic angular distribution slightly modifying R Y = ko + k1Sl + k5135, v'~~o where Si;~ are form factors.

Diamond: After annealing at 500 C for 7,5 h, the lattice spacing decreased from 3.,592 kX to 39574 M The intensity of the diffuse scattering maxima did not change noticeably. After further annealing at 9000C for 1 hour: 3,566 kX; the intensity of the maxima becomes noticeably lower. In the course of a further treatment at 12000C for 1 hour the lat- tice spacing decreased still more.

It is used both for research work in nuclear physics and reactor engineering; obtaining of new,,transuranic elements, testing of fission and building materials under neutron and gamma bombardment, within the temperature range 200K - 20000C, and in various media; spectrometric examination of intermediate neutrons; examination of the gamma spectrum of the (n,7) reaction; examination of short-lived isotopes and neutron diffraction analyses. The authors first discuss some characteriatic data. Card 1/5 kAl_~ The GM (SM) Research Reactor With a Capacity of 50 Mw S/085/60/008/06/01/021 B006/3063 82-IM The water-cooled, reflected reactor works with U235 en:iched to 90%. The critical mass (without the experimental holes) is 7-3 :cg of U235# and including the experimental holes, it amounts to 9o5 kg (loading:.- 11-7 k6 The maximum heat flow from the fuel element attains 5.5#106kcal/ml.h; the surface temperature does not exceed 1950C. Fig. 1 ishows the distribution of the neutron flux in the cross section of the reactor; the flux has two maxima, 6ne in the center of the cooling-water cavity (2.2-jo15), and the other in the lateral reflector (5-iol4n/cm2sec). The flux/Power ratio is 4-4-1010n/ With a 25% submersion depth of the fuel elements, the reaeftor can be in continuous operation for a period of 60-65 days. Several details are dealt with next. Experimental holes: The reactor has five horizontal and fifteen vertical holes. The horizontal ones are in the central part of the active zone, whose longitudinal and cross sections are shown in Figs. 2,3. At the output of the holes the neutron flux amounts to V3-1010n/cm2sec. The vertical holes are located in the reflector with the exception of the central ones. Three of them serve for obtaining transuranic elements (one.of these being in the center), two low-temperature holes serve for metal Card 2/5 or.", The CIM(SM) Research Reactor With a S/089/60/008/06/01/021 Capacity of 50 MW B006/BO63 82302 tests, two high-temperature holes for the testing of fuel elements, chemical analyses of the cooling water, and corrosion tests. All of these holes are water-cooled. Furthermore, five gas-cooled holes serve for testing fission and building materials in the range of 0 - 6000C; one hole (cooled with helium gas or liquid H2) serves for material tests at low temperatures; one gas-cooled hole for material tests at -.,20000C; one hole cooled with liquid metal (10000C) for tenting fuel elements and coolants. Construction: The following demands were made on construction: creation of a small active zone that would withstand high thermal loads for a long time, and its cooling; application of a maximum number of experimental holes (their distribution is shown in Fig. 3); possible exchange of fuel assemblies without pressure drop. Figs. 2-5 illustrate particulars of the construction. Reactor body and cover: Pig. 2 is described. The cylindrical part is made of 36 mm thick stainless steel of the grade IX49497* (1Kh18N9T)- The reflootor consiate basioally of boryllium oxide; it is made up of blocks comprising about 65 different types, which a~e enclosed by steel plates on top and at the bottom.

The cylindrical-. body shield-(Pig. 2) dividee'the inner reactor cavity into two zones. The functions of this shield are briefly discussed, and the cooling water circulation is described next. The control system is described in greater detail. This system consists of two automatic regulators with two regulation rods each, four shim rods, and four safety rods which can also be used as shim rods. The automatic regulation is operated by 13 ionization chambers located outside the reactor body; it covers the power range from 0-5 to 10Q%. Several details concerning safety and shim rods are thoroughly discussed. Reactor shield: Fig. 8 shows a cross section through reactor plus shield. The latter consists of steel and heavy concrete. A few details are described, and the process of fuel extraction is briefly dealt with. The cooling system is finally discussed. It consists of four closed, separate loops. The water is kept flowing by circulating pumps (500 t/h, 10 atm); the heat exchange power is 15 Mw- Card 4/5 VY 82955 S/089/60/009/003/004/014 .'q/ C .9-0 0 BOo6/BO63 /.P, P.2-0 0 AUTHOR: Konobeyevskiy, S. T. TITLE: Relaxation r Elastic-syresses Under the Action of Neutron Bombard!"t PERIODICAL: Atomnaya energiya, 1960, Vol. 9,-No. 3, PP. 194-200 TEXTA. The author discusses the results of an inve 'a'tigation of the effect of neutron bombardment on the relaxation of elastic stresses in flat 3prings of uranium-molybdenum alloy as well as on the relaxation of microstresses Phich lead to a broadening ofthe lines of an X-ray diaCram of rolled uranium. First of all, the author gives a survey of experimental studies and their,results which have been described in detail in a pre- vious paper (Ref . 1). The samples - flat s8rings of U-Mo alloy 30-1,5'0#1 MM large - were tempered at 570 C for one hour, after which some of the samples were exposed to a flux of 1-5-1013n/cm2see, while the remaining samples were subjected to a continuous heating (22-00 0C). The sag of the springs was measured before and after neutron bombardment, Uranium alloys with molybdenum admixtures of 0.91 and 9.0% were examined. Card 1/4 82955 Relaxation of Elastic Stresses Under the' S/089/60/009/003/004/014 Action of Neutron Bombardment Boo6/BO63 The sag of both samples was reduced by irradiation; the greatest change was found w1thin the first two hours (integral flux: 0.5*J017_1.O.1O17r/,:4)- The effect of irradiation on elastic stresses is shown in Fig. 1. After a jump-like drop, the stress decreases more slowly. These two stages take a different course for the two samples (a-uranium with 0.91% Mo and 1-uranium with 9.0% Mo). The former sample shows a less jump-like decrease of stress and later only a slow decrease (by 25 - 30% within 100 hours)t whereas 'the stress of the latter first drops very rapidly, followed by a slow decrease (from 24 to 2 - 3 kg/mm2 within lo hours). Numerical sag values, measured for two samples of U-No alloy (9.0% MCI) ef the lype YM -9 (U.V-9), are compiled in a table. The observed varia- tions of the line vidths in the X-ray diagram with time, and the cor- responding value3 of the microstresses a are shoun, in Fig. ~, for a- uranium and in Fig. 3 (Ug-?,alloy) fcr ?-uranium (for the lines 114 and 222, respectively, at 2-10 n/CM2-sec). In the first case, a decreases rapidly during the first hour, after which it shows a slight linear rise. In the seoond oase, there is an exponential decrease. A discussion of these experimental observations is followed by the theory of relaxation Card 2/4 E?955 Relaxation of Elastic Stresses Under the 3~089'60/009/003/004/014 Action of Neutron Boubordsent B0067'.iO63 effects.,Experiment andtfisoryAndicate that'relaxat.:Ion is primarily due to the occurr .ence and -displacement of atomic deft-Ots (intersti.-tial atoins and.vacancies)o The fact that bonbarded a-uranlum -shows anomalous creeping "isknown. The accelerated relaxation studicd by the author nay be interpreted as a primary.radiation effect. Fivigion events producing thermal peaks in uranium and its alloys have two effects in'this case: 1) Volume expansion occurring in the region of the peaks produces a large numbzr of point defects-and facilitates natural diffusion of atom's of the bombarded-substance. 2) Heat liberated in this region increases atomic mobility and causes displacements. The acciumulation of point defects playa the main part in the region of reversible relaxation* Irreversible relaxation effeicts, 'occurring in a-uranium at an-integral flux of ' 5.iO17 n/cm 2, are closely connected with radiative activation of the natural,diffusloh of defects in the field of stress.

COMAGE: This is a collection of papers presented at the Moscow Conference on the Effect of Nuclear Radiation on Materials, held December 6-10, 196o. The material reflects certain trends in the work being conducted in the Soviet scientific research orginization. Some of the papers are devoted to the experimental study of the effect of neutron irradiation on reactor materials (steel, ferrous alloys, molybdenum, avialgraphite, and nichromes). Others deal with the theory of neutron irradiation effects (physico- chemical transformations, relaxation of internal stresdes, internal friction) and changes in the structure and proper- ties of various crystals.
