TITLE- A pulsed fast reactor
PERIODICAL: Atomnaya energiya, v. 10, no. 5, 1961, 437-446 a
TEXT- The present paper g"ivee a description of the pulsed fabt reactor of
the Ob"yedinennyy inatitut yadernykh iosledovaniy* (Joint Institute of
Nuclear Research) which became critical in Juno, .1960. This reactor,
called ij6P (IBR) reactor, serves as pulsed fast neutron source (mean
power Z I km) for physical inveotiqationa, particularly for time-of-flight
experiments. Its most diatinguishing feature is the very small contribu-
tion '(Njo-4) of the delayed neutrons in Its normal operation; it is about

appear because whenever the reactor becomes overcritical a burst. of prompt
neutrons results. The half width of those pulcon in 36 goes. The
frequency with which the pulses are ropented can bQ varied betwoon 0 and
00 pulsoo/sea. Fig. 2 Bhown the construction of this reactor. The
periodic change in the reactivity is brought about by the dioplooement of
the two U235 blooko placed in two disks that can be rotated. The main
block is pressed in the form of a disk, 1100 mm in diameter, and can be
rotated with a peripheral velocity of 276 mlaeo (at 6000 rpm) during which
It passes through the core center. The reactivity change obtainable from
the motion of the main block Is 7,4 ~r that obtainable from the motion of
the auxiliary block in 0.4 ~. The stationary part of the core consists of
plutonium lumpo in steel jackets. The reactor ia started by a =ough
regulator, in this case a movable part of the reflector. It gives a

reactivity change at the rate of 13-10- 1.3-10 Bee The manually
operated rod is also a part of the reflector. Two plutonium rods in
electromanetic suspension serve as scram. They can be separated from the
oore with an acceleration of 20 g. Their separation causes a reactivity

2,4 %, the manual regulator 0.1 %, and the automatic regulntor 0.036 ~.
The reactor possesses also a reiietivity booster for the produc*,ion of one

functioning electronic arrangement with BF 3counters and ionization
chambers. The whole reactor 10 PlAOed'In n room of size 10-10-7 m whose
concrete walls allow complete protection from radiation. Themost
important experimental arrangement consists of a 100D m long neutron
conductor, a metal tube, 400 mm in diameter In the first part and 800 mm
in the second part in which a pressure of 0.1 mm Hg Is maintained. This
conductor conneots a chain of soaalled "intermediate pavilions" (at
distances of 70, 250, 500, 750* and 1000 m from the reactor) In which
experiments can be carried out. Thor* Is also an additional neutron
conduator of 100 m length. The reactor chamber In joined to an experi-
mental chamber In which four neutron beams of up to 800 mm diameter are
available. There us ouch an experimental chamber also above the reactor
chamber. Varioun experiments were carried out with the reactor and they
are described in the present paper. These are experiments with stand

TITLE: The extraction of microquantities of cerium from

PERIODICAL: Radiokhimiya, v.4, no-3, 1962, 279-289
TEXT: In order to elucidate the mechanism of extraction of
inorganic nitrates with neutral and acid extracting agent
the authors investigated the extraction of trivalent CeM
(used in indicator quantities) with isoamyl esters of
methylphosphinic acid. The extraction was done by mechanical
mixing in graduated test tubes at 20 + 2% and a constant ionic
force of about 2. On extraction witi; diisoamyl ester of
methylphosphinic acid (DAMFK) the constants of complex formation
were determined: for benzene and xylene as diluents 12 + 3
and for kerosene 62 + 1.5. The thermodynamic constant for
benzene as a diluent was determined as being about 30 to 40.-

was calculated ?0.1'2*6 + 0.002). The influence of the
concentration of nitri'j acid, thorium nitrate and N05 ion in the
aqueous phase on the distribution of cerium was studied. A sharp
decrease in the coefficient of distribution of cerium in the
presence of thorium nitrate was observed. On examining the
influence of the presence of mono ester in diester on the
extraction of cerium, it was established that the presence of the
former increases the extraction of cerium, probably due to
synergetic effect. At low acidities, the effect is considerable.
The form of the dependence of the activity coefficients of
trivalent cerium in nitric acid solutions on the concentration of
nitric acid was determined. A sharp decrease of activity
coefficients with increasing concentration of nitric acid indicates
the prevalence of interactions of the type of ionic associations.

TOPIC TACS: thorium, metal extracting, partition coefficient
ABSTRACT: The extractive-properties of diisoamyl methylphosphonate (DAMP) in the
extraction of thorium from nitric acid solutions were studied. Since water and ni-
;tric acid are integral parts of these systems, their extraction with DAMP was also
investigated. The diluenta employed for the extracting agent were benzene, p-xylene?
an
d CC14. DAMP-solutions in xylene and benzene were found to be more effective ex-j
tractants than tributyl..phospbate. Extraction of HN03 with DAMP involves the forma-4,
tion of the complex HNO -A O-DAMP with K = 0.41 * 0.03. Extraction of H20 involves
