[Text] The radiochromatographic method of purifying gaseous wastes from
atomic electric power plants has been embodied in the :~chnological procedure
for special gas purification in atomic electric power plants with water-
moderated water-cooled power reactors and has been practically implemented
in operating electric power plants (Novovoronezhskaya, "Loviiza," in Finland,
Kol'skaya and Armyanskaya). On the basis of this method the UPAK system is
now being developed for atomic electric power plants with uranium-graphite
boiling-water channel reactors. For purification of wastes of radioactive
- iodine there are available several adsorbers using charcoal, in plain or re-
mote operation, with various capacities (AU adsorbers 1500-200-400 m3/n with
grade SKT-3 charcoal, AUI adsorbers with impregnated charcoal. For proper
design of gas purif ication systems systematic data are needed on the compo-
sition of wastes, on the operating experience, on the service life of iodine
filters, and so on. Recently the FARTOS-2500 filter has been developed with
a 2500 m3/h capacity.

(Text] A study was made in 1974-75 for Che purnose of determining the basic
ptiysico-chemical and radiational properCies of ~erosols in air ducts and in
rooms of atomic electric power plants with water-moderated water-cooled
power r.eactors. It has been discovered Chat the concentratian ot radioactive
aerosols in air ducCs and rooms of such a:.omic electric power plants is
small, not exceeding 5~10-13 curie/liCer, under normal conditions. During
periods when the nuclear fuel element, are overloaded their concentration
incre~ses and can reach 10'11 curicjliter in individual air ducts or rooms.
The activity of particles is characterized by a log normal distributien with
respect to their aerodynamic dimensions, and the averaged parameters of this
di~triburion under normal conditions are: aerodynamic median diameter 0.9-
4.5 um and standard deviation 1.9-2.6, Under normal conditions the filter-
ing material in D-23 KL filters becomes clogged with inactive dust mainly.
The acrivity of a used filCer does not exceed 5.10'3 curie after one year
in service. On the basis of these results of the study there has been de-
_ veloped the I~AR filter with UTSV material for use in atomic electric power
plunts. -

(TexC] The fundamental differenc e is shown between gas bubbles in irradiated
, uranium dioxide and bubbles which form ~n gas evoluCion experimenta after ex-
traction of irradiated samples f r om a nuclear reactor. During ir.radiation
Cheofission gas evolves from a nuclear fuel element in the form of bubbles,
20 A in diameter, migrating through the crystal by Brownian motion. Further-
more, the open surface of uranium dioxide increases during irradiation. On
the basis of these two factors there has been developed a phenomenological
model for calculating Che gas discharge and the changes in fuel volume in
containerized fuel elements. Figures 9; references 15.

scribing xhe effect of porosity of stabilized materials~on their heat re-
sistance. Changes in the disloc ation density depending on the test tempera-

[Text] t1 suxvey is given of ~tudies concerniiig the problem of a radiation-
resistanC uranium fuel for nuclear power reactors, including the KS-150
heavy-cuater gs~s-cooled react~r. Considered are the various faceors which
limit the viability of uranium fuel elements and various ways of suppressing
these factors. Particular attentj.on is paid to possible causes of inadequate
radiational srability of uranium fuel rods and to the progress which has been
made in this area so far. Some most general problems in the technology of
nuclear fuel production are discussed. The main data are given on actual use
of a developed nuclear fuel in laboratory reactor loops and in the KS-150 in-
dustrial heavy-water reactor. The results confirm that this nuclear fuel
has an extraord inar ily high radiational stability till burnout down to 1.5-
2%. The successful solution of a large complex of problems associated with
development of a nuclear fuel on the basis of inetallic uranium opens up new
possibilities f.or the use of such a fuel in nuclear power reactors. Figures

('fext] Reliable and efficienC nperation of thermal power equipment requires
thgt n large volume of input and design data be processed by a computer and
~tored in iCs memory. In existing information and computaCion subsystems all
programs are stored in the direct-access compuCer memory, and external media
are used only f.or storing numerical data filea. This reatricts the poasibili-
tles of expanding the scope of ~obs and of improving precision as well as the
representativeness of c~lculations. The sofCwere atructure in the automatic
control system for technological processes installed at the 800 MW unit of the
Uglegorskaya state regional elec[ric powar p1anC is design for use on an M-
6000 computer and is based on a real-time disk operating system, supplemented
with individual systemwide programs and library subprograms. All programs
fall into two categories: resident routines in the direct-access computer
memory nnd resident routines on magnetic disks. The data base consists of
files either in the direct-access computer memory or on magnetic disks, ac-
cessible to all programs of the complex. The proposed structure allows for
easy ~xpansion of software.

(Text] The ori~{nal design of the 800 MW power unit at Che Zaporozhskaya
stat~ regional electric power plant provided for automation of seven function-
al groups: turbine drainage, 0{1 supply for turbine lubrication and regula-
tion system, heating of flangea and pins of the high-presaure cylinder and
' the medium-pressure cylinder, the turbine sealing system and the turbine it-
self. It was decided to addiCionally automate eleven more functional groups
on the turbine side and eight functional groupe on the boiler side, based on
ZShIIVU ("Ukravtomatika") logical control equipment. The originally designed
technological control algorithms had to be substantially corrected in the
course of development and adjustments. The devices for controlling some
functional groups have already been completely adapted for operation. Those
for the remaining functional groups are either still being developed or built,
or are already being adapted for operation. (Southern Power Engineering and

[Tex.t) An examination is made of the motion of a dynamically symmetric solid
relative to a center of mass in a central newtonian gravitational field. In
a circular orbit, a solid may undergo three kinds of regular precession: coni-
cal, hyperbolic and cylindrical. For these three kinds of motion, the axis of
symmetry of the solid occupies a fixed position in the orbital coordinate sys-
tem. In particular, in the case of cylindrical precession the axis of sym-
metry is perpendicular to the plane of the orbit of the center of mass, and
the solid rotates relative to the axis of symmetry with an arbitrary angular
velocity of constant magnitude. A detailed analysis is made of the stability
of cylindrical precession. Figure 1; table 1; references 7.

trolled body about a center of mass in the atmosphere. Approximate formulas
are given fcr the case o� motion of an ideal axisymmetric body, relatiing
probable values of the amplitude of oscillations to the conditions of entry
into the atmosphere. An examination is made of moCion of a body with low '
aerodynamic and mass asymmetry, and the basic principles governing Chis mo-
Cion are determined. Particular attention is giv~~n to inveatigation of the
resonance phenor~enon in the nonlinear formulntion. A brief examination is
made of the particulars of motion of a body that does not have axial symmetry.

[Text] The speed of sound is measured in binary mixtures of nitrogen with
methane and helium in the pressure range of 200-4000 bars at a temperature
of up to 200�C. The density of mixtures of nitrogen with methnne is mea-
sured at 50�C. The adiabatic compressibility and Cp/C~ of the given mixtures
are calculated on the basis of P-V-T data obtained by the authors. Tables 4; -

[Text] The collection contains papers dealing with flow around bodies with
consideration of physicochemical processes, as well as studies on flows of a
relaxing gas. Results are given from research on supersonic flow around
bodies with consideration of intense blow-in from their surface in the prea-
ence of combLStion and nonequilibrium chemical reactions, on flows in a noz-
zle and on ini~iation of detonation in a mixture of ozone with oxygen. Con-
sideration is also given to problems of determining the optimum shapes of
supersonic flightcraft. The collection is intended for scientific workers,
graduate and undergraduate students interested in problems of modern physi-
cal gas dynamics and aerodynamics. .

[Text] An examinACion is m~de of the::problem of tiie optimum shape of an
axisymmetric body with respect to the minimum total convective heat flux
over the lateral surface. Laws of heat flux similarity are esCablished thaC
enable scaling to geometrically similar bodies. Variational problems are
sdlved for the body of minimum heat flux wirh different combinaCions of
radius, length, midsection and volume of the body. A comparison is made
with the numerical results of other studies, and the heat fluxes to the opti~
mum bodies are compared wiCh those to bodies of simple shape. Good agreement
with the results of other studies shows that the given simplified functionals
for determining heaC flux can be used Co solve the variational problem on the
tra~ectory of motion of a body. Figures 15; references 17.

[Text] An examination is made of hypersonic flow of an inviscid thermally
non-conductive radiating gas around an axisymmetric blunt body. Another gas
(oxygen) is injected through the surface of the body at a given velocity.
Nonequilibrium processes of collisional dissociation and photodissociation
of 02 moZecules are considered in the injected gas layer. The complete sys-
tem of equations describing such flow is written out. Approximate analyti-
cal solutions are found for the~system of gasdynamic equations in the in~ec-
_ tion layer for limiting cases. Gas concentration [and] temperature profiles

tunnels. A perforated working section of a wind tunnel is known that has
panels with perforated holea. However, such working aections give rise to
ncousCic interference ti~at induces additional optical interference in the
field of the shadow camera in the form of a fluctuating network of perturba-

[Text] An examination is made of the problem of determining the stressed
and strained state of a cylindrical sandwich shell freely supported around
the edges and reinforced by a stiffening ring located in the center of the
span. A uniform transverse load is applied to the reinforcing ring, which
is made of the same material as the outer layer. An algorittun is construct-
ed for solving the problem, and an example is given that illuatrates the
influence of the ring on the stressed and strained state. Figures 4; refer- `
