Copper, iron, nickel and aluminum vere annealed at 700 C for the first two, 800 C for the
third, and 400 C for the last, and subjected at temperatures of 250-300 C to neutron
integrated flux of 1.1-1.4 nvt. 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.

By applying different research mathods (metallographic, X-ray diffraction, thermal,etc.
worked out for quantities ranging from 10 microgrammes to 100 milligrammes of a metal the
binary diagrams of plutonium with a number of metals were studied. 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.

irradiation, the creep rate was higher by a factor 1.5 to 2.0 'old rolled uranium
showed considerable ani.,zotropy in the value of electircal conductivity along and
transverse to the rolling direction. Irradiation caused rolled uranium specimns
to incroase substantially along the rolling axis. Alloys of Mo with U Containing

Abutract: A review is given of the theory of the radiation damage to materials ir-
radiated by fast particles. An attempt is made to describe the processes of the
phase conversions during neutron irradiation of fissionable materials with the aid
of the diffusion equation. An expression is obtained thereby for the diffusion co-
efficient D. Examination is made of the possible result of the effect of thermal
peaks on the structure of the o(+ Y eutectoid in annealed U-Mo alloy.

Abstract :A setup for the investigation of highly radioactive materials vas con-
structed around a Norelco type ionization x-ray speatrometer. 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. If the shielding is reinforced, the setup

ABSTRACT: Theoretical paper. 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

vacuum induction furnace. The melting charge is rolled out in a warm
cold state until a thickness of 091 mm is attainede From these
fails the samples for measuring resistance and for radiographic insi
vestigations are produced, Before irradiation with neutrons, the
samples are subjected to a homogenizing process of annealing (in the
vacuum) at a temperature of loco0c for "JILree hours, after which they
were cooled in the airs
After irradiation by neutrons the electric resistance was measured
and the structure of the alloys was investigated radiographically

The modification of the lattice spacing in the case of a
diamond causes the double scattering in the X-ray picture
to vanish. In order to find out whether this vanishing is
of permanent duration the crystals were annealed. The fol-
lowing results were obtained: .
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. The initial value was,
however, not attained,

TEXT: The present article gives a detailed description of the Russian
50-Mw research reactor which has a neutron flux of 2.2*1015 n/cm2sec.
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.

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/CM2.sec.kw. 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

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. Fuel

core is contained in a nickel can. Fig. 6 shows a section through the
assembly, Fig. 7 another through a fuel element. Data rf one such
element are compiled,;. every element, contains 12-5 g tT2~.,. 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-

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.

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

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

PURPOSE: This book is intended for personnel concerned with
- nuclear materials.
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. Special attention is given to
the effect of intense Y-radiation on the electrical,
magnetic, and optical properties of metals, dielectrics..
and semiconduc'u-orals
