ABSTRACT: A conference was held on this topic at Moscow on November 20th and 21st;
more than 20 scientific lectures were held on that occasion. D. I.
ZAKUTINSKIJ, in his general. survey reported on the results obtained by
Soviet research workers in the course of recent yeaxs. ZAKUTINSKIJ paid
special attention to the influence of radiation energy on the progeny
of animals that had taken radioactive substances. The new data given by
the lecturer showed the destruction of the sensitivehess of the animals
treated in this way to a number of medical preparations. The major part
of the lecture dealt with the problem of the detrimental effects on
growth exercised by radioactive substances. - Same lectures dealt with
the condition of the blood-forming organs a long time after they had
recovered from acute or chronic radiation diseases; many new results
were discussed. Among others, the following topics formed the subjects
of reports: In the case of rabbits which, from 6 to 12 months previous-
ly, had been irradiated by strong doses of fast neutrons, the process
of blood regeneration took 2-6 months where erythocytea, and up to
1,5 years where leucooy-tes were concerned.Acute radiation disease

SWFNESS (Russian text) - Shikhodirov V. V. - ARKII. PAT01'. 1957,
19/9 (35-42) Illus. 4
Experiments'an 70 dogs, 180 rats and 100 mice. Acute radiation sickness was
caused by whole-body radiation With X-rays or by the introduction (i.v. in dogs.
intra-abdominally in rats) of Sr89 and Sr9O (0.8 to 1.6 me./kg.). To obtain a con-
dition of chronic intoxication only 0.4 to 0.2 mc./kg. of radioactive Sr were ad-.
ministered. The mast cells were studied from patch preparations of back.or thigh.
Breakdown of the mast cells with release of the enlarged granula was observed
after a few hours in dogs, in the first 2 days in rats and mice. In the next few
days the number of mast cells clearly decreased and their cytoplasm became de-
granulated. A solution of cysteine (1 mg./g. body weight) injected intraperitoneal -
ly into a number of rats before the radiation (600 r.) caused it decreased break-
down of mast cells. The same result could be obtained by.the 3-1fold injection of
myelocytotoxic serum (0.1 ml. of an 0.02T6 solution); this was regarded as to be
due to a stimulation of the connective tissue, because it also caused a regeneration
of the mast cells. In cases of chronic radiation sickness there was an increase of
the mast cells with increased granulation during the first 3 to 4 months; after-
wards decompensation occurred and the phenomena appeared as described for
acute radiation sickness. Brandt - Berlin (V, 14, 16)

Twelve dogs were irradiated with a cobalt bomb (554 r./min.); after various inter-
vah (front dirtctlv after the irradiation to 9 hr. later) patch preparations were made
from the tipper part of the hind leg and subjected to the usual connective tissue
staining. Even immediately after & irradiation, disintegration of macrophages.
mast cells and young fibroblasts can be seen; the last-mentioned show an excessively
rapid maturation. The pericytes disappear, the collagenous fibres swell and dissolve,
the argyrophile fibres disintegrate. The interstitial substance ;Shows intensive
metachromatic staining. The animals died 15-27 lir. after the irradiation; at that
time all the macrophages and fibroblasts had disintegrated, with only shrivelled
nuclei remaining of the latter. The mast cells showed a marked decrease, the
collagtnous and argyrophile fibres and the ground substance presented the same
alterations as described above. There was also a congestive hyperaernia with
Stasis and peripheral leucocytosis. *andt Berlin

TITLE: A system of digital programming control of a milling
machine with power step motors
PERIODICAL: Avtomatyka, no. 2, 1960, 81-83
TEXT: The article describes a bi-coordinate system of digital pro-
g-ramming control for power step motors which was constructed in
the Instytut elektrotekhniky AN URSR (Electrotechnical Institute
of the AS UkrSSR). Details of the motor are given by B.O. Sihov
(Ref. 1: Avtomatyka, no. 1, 1959). The program was written on
punched type and is read off by a transmitter which works in syn-
chronism with a linear interpolator. In the program are indicated
the sign and quantity of the displacement with respect to the co-
ordinates. The working of the system is possible both as an inter-
polator and as an intermediate memory. The programming scheme is
c@
constructed in the form of two separate blocs. In the first bloc

calculation for a reactor core volume of 200 - 1000 dm3. The
nine-group constants were determined according to Soviet and
foreign calculations published up to 1955. The results of the
work were discussed with A. I. Leypunskiy,, Regular Member

TITLE: A Method of Averaging'Nuclear Constants for Calculations
of the Fast Reactor, Taking Into Account The Value of
Neutrons
PERIODICAL: Atomnaya energiya, 1960, Vol 8, Nr 3, pp 209-213 (USSR)
ABSTRACT: The authors describe a method of averaging many-group
constants for the single-group computations of the cri-
tical volLune or critical mass of a two-zone fast reactor.
Usually, for computations of single-group cross sections,
one estimates approximately integral spectra separately
in the active zone and in the shield, and afterwards,
the Initial many-group constants are averaged over those
spectra. Trial computations showed that the critical'
mass obtained by means of an averaging over neutron
spectra of many-group constants is 10-20% lower than
the critical mass obtained by solving the many-group
spatial diffusion system of equations. One obviously

fiooion neutrons per one fission caused by a neutron of
the k-th group. In Eq. (1) the group number increases
with the decrease of neutron energy. Spectra of the
neutron flux and neutron importance obtained from
conjugate Eqs. (1) and (2) are then used for the separate
averaging of the constants in the active zone and in
the shield. The single-group constant obtained permits
a reliable computation of the critical load of the
reactor without solving the spatial many-group diffusion
probldm. When solving (1) and (2) one assumes that the
loss into empty space is zero (for a thick enough
shield), while the escapes from the equivalent bare
reactors are counted as auxiliary (inner) sources of
the screen. The solution can be written in the form
proposed by L. N. Usachev:

convenient for the computation of multizonal reactors,
it requires prior notions about space and energy

parameters of the two-zonal reactor. They com@uted
the composition of the active zone and screens for
three types of fact reactors. They also showed (see
Table 2) that single-group cross sections, computed
with and without contribution from neutron importances,
could be quite significant. The method of calculating
critical load of fast reactors outlined in the table
is applicable under the following conditionst (1) The
thickness of the shield must be of the order of 2-3
effective diffusion lengths. (2) There should be no
edge effects in the shield; such effects could be pre-
sent in case of intermediately fast reactors with '
hydrogen-containing materials In the shield. (3) The
size of the active zone should be larger than 4-5
single-group free path lengths of the neutrons. Small-
er zones would require corrections in equations used,
which would account for kinetic effects in gases. (4)
The method was checked for reactors with not more than
2 zones. There are 3 Tables; and 2 Soviet references.

TEXTt Critical-mass calculations in one-group approximation with averaging
of the constants yield good results only when no boundary effects arise
(Ref. 1: Atomnaya energiya, 8, 3, 1960). Si 'nee this is not the case wit h
intermediate systems, the authors develop-a two-group method for use
together with averaging of the constants as described in Ref. 1.- The
spatial multi-group problem is reduced to a two-group problem in the follow-
ing wayj The m-group system of equationa that describes the interaction
between neutrons and medium in the fast and intermedlate regions, given in
diffusion multigroup approximation, is solved as in Ref. 1. From this an
expression for k eff is obtained which is compared with k eff calculated in

An effective two-group ... B102/B186
two-group approximation for a'non-reflected reactor. Hence the two-group
.constants are obtained. This*system of constants for the epithermal
region is related to the spectrum of neutron importance. The constants
are averaged for systems with and without reflector and the constants of
the reflector are determined by comparison. The success of the two-gr@up
method depends considerably on the quality of averaging of the multi-
group constants in the resonance-energy range. The two-group method was
verified by numerical calculations and by comparing the results with those-@-
of a 15-group approximation for a homogeneouz spherical system with:-
riched uranium and-hydrocarbon moderator and reflector. The 15-group
method yields Ror - 36-0 cm and keff 0 1.007, the two-group method
Ror - 37-8 cm and'k eff , 1; these results show that both methods can be
considered as equivalent.
