TITLE An Investigation of the Iodide Method of Refining Zirkonium.
FERIODICAL Atomnaja Energija, .1, faso. 1, 43-51 (1956)
Issued* 3 / 1956
The present investigation served the purpose of explaining the principles of
the process of refining as well as of problems of practical interests.
Tests were carried out in small glass- and quartz vessels under
10-4 mm vacuum, in which glowing tungsten wires fastened by molybdenum holders
were used as seperators. Temperature was neasured by means of pyrometers.
Besides contradictory statements made in literature concerning the influence
exercised by the temperature of the wire on the course taken by reaction, a eon-
siaerable dependence was found to exist within the range of operation of from
1200 to 15000 0, In contrast to statements made by other authoral who believe
in a slight inareaso of dienociation constants within the range above 14500 Ct
it is assumed that ZrJ -partial pressure near the wire cannot increase infini-
tely because the partill pressures satisfy the equation P j - PZrJ4 0 Ptotal'
The influence exercised by the quantity of iodide on reaction velocity:
In the case of small quantitieet 3 - 5 mg/50 9 Zr, reaction is very short,
apparently because of the formation of low iodides. The curve shows a distinct
maximum at 12 mg/1000 CM3 vessel volume.

Atomnaja Energija, .1, fasc. 1, 43-51 (1956) CARD 2 / 2 PA - 1604
For the dependence of the precipitation velocity on vesnal temperature (and
thus on the temperature of the metal) different authors give different data.
It was found that, on the assumption that the temperature of the ZrJ4 is con-
stant, and assuming an optimum steam pressure, the temperature of the vessel
can vary between 235 and 7000 G without reaction velocity being influenced.
In the course of the investigation of the problem as to the existenoe of a
second maximum above 4200 C the following two oases were distinguished:
1. If Zr is fine, i.e. if its surface is large, low iodides will form, and at
higher temperatures tetraiodide will be formed which leads to a 2. maximum.
2. In the case of small quantities of the metal in large pieces, there will
always be a surplus of Zrj4 whioh determines the vapor pressure and thun tho
reaction velocity, the optimum of which is at about 235-2400 0-
This hypothesis was confirmed by a further experiment in the course of which
vapor pressure was measured in the vessel.

TITLE The Investigation of Systems of Fused Salts on the Basis of
Thorium Fluorido. Note I: Investigation of the System
ThF4 - Ila Cl - M.
PERIODICAL Atomnaja Energija 1, fasc, 4, 107-112 (1956)

The system NaCl - M - ThP and the systems NaGl - ThF and M - ThF
4 4 4
therein contained are of importance for the' selection of the electrolyte on
the occasion of the winning of thorium by means of electrolysie.
The main method employed by the authors for the investigation of these state
diagrams was the thermal analysis (with automatic recording of the simple and
differentiated curves) of the fused salts. As'an auxiliary method they chose
phase analysis by the direct comparison of the X-ray pictures obtained with
those of pure raw materials; ThP 2 IlaCl and KC1. Furthermore, microstructure
analyses of the microsection surlaces of these salt alloys were carried out.
Production and properties of the material examined are described. There follows
the discussion of the investigation of the systems KaC1 - ThF 4 and KC1 - ThP 4'
Conclusions: The state diagram found here of the system HaCl - ThP 4 belongs to
the diagrams of euteetic type with lacking displaceability of components in the
solid stste. The eutecticum is at 23 molecular percents ThF 4 and 7120 C.

Atomnaja Energija,.I, faso. 4, 107-112 (1956) CARD 2 / 2 PA - 1519
The state diagram of the system XG1 - ThF 4is also of the eutectic type with
the eutecticum. at 23 molecular percents ThF4 and 704 0 C. The components Of
this system are practically insoluble in the solid state#
On the occasion of the fusing of KC1 and ThP 4 in the presence of oxigen or
humidity, complex compounds of the type K xThyFX+4Y are produced, where x- 1,
y - 2 or 6. Also these complex compounds with KC1 give diagrams of the
eutectic type.
in conclusion a polythermal section of the 'triple system RaCl - KCI - ThF4
through (1 NaCl : 1KC1) - ThF is constructed. On this section the lowest
4
point of the line of eutectic crystallization is at about 40 weight percents
ThF4 (12t6 molecular percents) and 6260 C.

By means of thermograph~c, roentgenographic and other methods of analysis the
state diagrams of the s.-ystem NaF - ThF 4 with four chemical compounds
(Na4ThF8; a-Na 2ThP 6,,P-Na 2ThF6' NaTh"5 , NaTh 2F9) and of the system Kf-ThF4
with 6 chemical compounds (K 5ThF 9), X3 ThP 7'K3Th2F11T KThF 59 KTh2F9VKTh6r25)
are.constructed.
Investigation of the system NaP -KY - ThP and of the therein contained systems
NaF-ThF4, KF-ThF 4 was carried out in conniction with the study of a multicompo-
nent electrolyte which is formed on the occasion of the continuous electrolysis
of the salts NaCl-KCl-ThV 4 by the accumulation of HaF and Kf. Investigation was
carried out by the methods of thermal-, roentgen-phase- and chemical analysis.
As initial material chemically pure NaFt KF and Th? 4 was used. The system KF-ThF 4
contains the chemical compounds K 3ThY 7' KThF5and KThF 131 which form 4 simple
euteotio systems. Also the 6 chemical compounds contained in the system KF-ThF 4
are enumerated.
Investigation of the system Na?-ThF.A was carried out on 35 alloys at intervals
of from 2 to 2,5 Itol-percents of Th?4 within the range of from 2 to 35 mol-per-

Investigation of the system XF-ThF was carried out on more than 40 melts with
intervals of 2-3 mol-percents ThP 4* This system is very complicated, it has 6
chemical compounds which are enumerated together with their domains of existence.
The syate_4aF-KF-ThF The domain NaP-Na 2ThF6-KThF 5-KFI which is of interest in
connection with the electrolytic winning of thorium, was investigated. On the
data obtained on this occasion this domain was triangulated for 6 trinary systems.
Investigation confirmed the existence of a new compound (phase X) of the compo-
sition NaK(ThF 6) with a noticeable homogeneity domain. A particularly important
domain of solid solutions was noticed on the section NaKThF6_K3 Th2Fil,
The Polythermal section of NaF-KThP . For the additional investigation of the com-
pound KNaThF6 a polythermal section or the aystem along the 0line NaF-KThP5 was
constructed. Results are shown in form of a diagram. At 665 C,NaKThF 6 decays
after a peritectio reaction, and at 540 0 C it is subjected to a polymorphous
transformation. The peritectio point on the horizontal of 6550 C is about 63 mol-
percents NaF. At 5700 0 and 31 mol-percents KThF the eutecticum. NaKThF

ABSTRACT: Taking the hypothesis that processes of diffusion are decis-
ive in the kinetics of the process of the transfer of Zr to a cen-
tral filament (F), it is shown that the rate of deposition of the
Zr on the F is directly proportional to the pressure of free I
near the surface of the F, and that this in turn determines the
temperature of the F. Inasmuch as the vapor pressure of the I
around the F cannot exceed the total pressure in the apparatus,
which is governed by the wall temperature, the rate of deposi-

pends upon the total pressure in the apparatus. These concepts afford an
explanation of the available experimental data of various authors on the de-
pendence of the rate of Zr deposition upon an F on the temperature of that F.
It is also shown that the quantity Of QA introduced by DUririg and Moli6re

dissociation by the expression QA" AH/4. If account be taken of the forma-
tion of lower Zr iodides on the surface of the F, the value Of QA, it appears,
is also dependent upon the vapor pressure of the Zrl4-

Received: 3 / 1957 Reviewed: 3 / 1957
ABSTRACT: This system wan investigated by methods of metallographyp thermal
analysis, electric resistanost h&rdneast and the X-ray-phase
analysis, and the state diagram was constructed. The difficulties
in producing zirconium-tantalum alloys were adjusted by smelting
the corresponding samples in the electric are oven MIFI-39-3
with a ooolable copper crucible. The samples were smelted in a
pure argon atmosphere. The production of the samples from
primary materials Is described. The cast samples were homogen-
ized by annealing at 12000, then ground and dry-polished.
Samples of non-annealed powder (which was taken from cast- and
chilled alloys of different composition) were subjected to an
X-ray phase analysis. The thermograme were recorded only up to
10000 by means of the recording XURNAKOV pyrometer.*Determination
of the solidue- and liquidus lines is then discussed.
Results of the investigation: The investigation of the micro-
oopic structure of the cast samples proved the existence of a
:
onsiderable domain of solid solutions of tantalum in zirconium,
as well as of an eutecticum and of a domain of solid solutions

of zirconium in tantalum. The X-ray-ph&s# analysis proved the
existence of only two phases in the systomt an a-phase and a
F-phasev i.e. a solid solution based on tantalum. The P-phase
of zirconium could not be stabilized at room temperature. The eu-
tootious is about 1585+150 0 and 34 atom Percents of tantalum.
The eutectio struoture-of such an alloy in shown in a diagram.
The maximum of solubility of tantalum in O-zirconium amounts to
16 and 17% atom percents respGotively in the came of metallogra-
phic determination. kn euteotoidal disintegration was observed in
alloys with some atom percents of tantalum. Various special cases
of alloys are demonstrated in diagrams. According to the data of
metallographic analysis the temperature of the eutectoidal dis-
integration amounts to 790+100 0, a fact which was confirmed by
thermal analysis. The grQaTest solubility of tantalum in a-zirco-
nium, was insignificantl it is less than 0,22 atom percents of tan-
talum. Based on these investigations the state diagram of the
system zirconium-tantalum was then constructed. In order to
examine these state diagrams also the electric resistances of
samples of the alloy were measured which were cast at 12000 and
7700 C and then chilled. Finally, also the hardness of the afore-
mentioned alloys was measured. Hardness increases if tantalum is
added to zirconium.

Zr.-Nb takes place at 612 + 130C. Addition of Nb to alloys in the
system Zr-Ta shifts the vZcimma of martensinic transformation to

TITLE- Atomic Energy in the USSR in the Future (Budushcheye atomnoy,
energetiki v SSSR)
PERIODICAL: Atomnaya energiya, 1958, Vol. 5, Nr 3, pp. 217-222 (USSR)
ABSTRACT: The reserves of organic fuels of every kind available in the
USSR are very considerable. Nevertheless, an extensive program
for the establishment of nuclear power plants is at present
being developed in order to gather experience for future power
plants. It is furthermore intended to prove that atomic kWh are
well able to compete with ordinary kWh. Near Voronezh a 420
megawatts atomic power plant is being built, in which two re-
actors, which are water-cooled and In which water is used as a
moderator (100 atm), will be installed. Saturated steam of
29 atm is conveyed to the turbines. 'Me fuel element3 are made
from uranium oxide. Enrichment amounts to 1,5% U235. The second
nuclear power plant of the same type will be established near
Leningrad. As soon as sufficient experience will have been ga-
thered by means of these reactors, steam will be produced in the
Card 1A reactors themselves. Near UllyanoVsk on the Volga a boiling-

Atomic Energy in the USSR in the Future SOV/89-5-3-1/15
water reactor with a power output of 50 114 is at present being
built. The fuel elements used correspond to those used in the
aforementioned plants. On the Volga a number of prototype
power reactors is at present being built In order that ex-
perience can be gathered with various types of reactors. In the
Ural a nuclear power plant with a 1,00 MW electric power out1lut is
being built, in which the steam is produced In the reactor itself
and is conveyed straight to the turbine. Four reactors will be
erected in this power plant, each of which will be connected by
direct coupling with a 100 IN turbine. The reactor produces steam
of 90 atm and having a temperature of from 480 to 50000. Me fuel
elements of these reactors are exactly the same as those of the
first Russian nuclear power plant. However, they are 6 m long,
instead of 1.7 m as in the first plant. Also a reactor of 50 IV
electric power output is being built cn the Volga, in which sodi-Lua
is used as a coolant. The reactor is intended to produce steam of
90 atm and 5000 C- The pressure under which the coolant is intend6d
to circulate in the reactor amounts to only 8 atm. The first re-
actor with fast neutrons,(zero energy fast reactor) was put into
operation in 1955. In February 1956 a 100 kW reactor for fest
neutrons was put into operation. The ruel. elements are made
from plutonitm and mercury in used tis a coolant. In July 1958
Card 2/4 a 5 14W reactor for fast neutrons was made critical. The active

crystals of the deposit are less contaminated by impurities than a deposit
on a liquid cathode. The crystals are bigger than the crystals of the
metal obtained by chemical methods. However, the deposit is never dense,
which is connected with the considerable lose of the electrolyte included
in the cathodic deposit. Consequently, the experiments were conducted in

TITLEs Mechanical properties of binary and ternary zirconium alloys with
tantalum and niobium at room and high temperatures

TEXT: The authors investigated the hardness and strength of cast and
hardened Zr-alloya with Ta (0- 100%) and Nb (0 - 20%) and also ternary alloys
containing up to 18% Ta and Nb. The hardness (HR) was measured In an argon
atmosphere, It was found that a maximum appeared on the composition - hardness
and composition - strength curves which can be explained by the transformation of
the ~-phase into the 0~-phaas. Alloying 2~iroonium with Ta and Nb increases the
strength and hardness at room and high temperatures. Up to 10% Nb strengthens
Zr to a greater degree than the addition of Ta.

TITLE: Close International Cooperation in the Field of Atomic Research
PERIODICALt Vestnik Akademii nauk SSSR, 1960, Nr 2j Pp 3-11 (USSR)
ABSTRACT% In this article the author discusses the problem of cooperation
between scientists of various countries* The present stage of
science and technology shows that large research programs cannot
be carried out any longer by small teams and that important scien-
tific problems can no longer be solved by one country alone. Thi5 %
applies especially to the problem of the use of atomic energy on
the solution of which depends the future of mankind. The scientlats
of the Soviet Union and other countries who concentrate on the
peaceful use ofatomic energy are making great efforts to establish
a fruitful basis for international cooperation which has already
been started after the First Oeneva Conference in 1955- Meanwhilo
Soviet scientists visited respective institutions and plants in

visit the Soviet Union. After 1. S. Khruahchey'a trip to the
United States in 1959 possibilities have opened up for cooperation
between American and Soviet scientists in the field of atomic
research. The author reports on an eleven-day visit of American
8cientiste to the Soviet Union in October, 1959, and on a 21-day
visit of Soviet experts to the United States. In the course of
these mutual visits scientists of the two countries were offered
the opportunity of visiting atomic research centers and plants
and of studying the present stage of research in both countries.
However, it would also be useful to establish a permanent cooper-
ation between the two countries as, e.g., for the erection of
joint research centers and the construotion of machines which in-
volve high costs of investmentp since research work is done in the
same direction in both countries. Mention is made of P. A.
