INTRODUCTION
Today, nuclear power plants account for about 15%
of global electricity production [1]. There are two main
reasons that prevent a wider spread of nuclear energy:
1. the remaining challenge of disposal of spent nu-
clear fuel in the framework of the modern concept of
nuclear energy;
2. the problem of utilization of stocks of depleted
uranium (238U) and thorium in energy production.
Fast and thermal reactors that form the basis of the
world accepted concept of nuclear energy development,
work on the controlled chain fission reaction with aver-
age energy of neutrons near or substantially below
0.2 MeV. This energy is determined by the fission neu-
tron spectrum (average energy of fission neutrons is
about ~ 2 MeV) and the structure of the reactor core.
Subcritical multiplying systems initiated by acceler-
ators (electronuclear systems or Accelerator-Driven
Systems - ADS) can technically work on a much more
harder neutron spectrum. However, the classical ADS
designs (an accelerator with energy of 1 GeV + a neu-
tron producing lead target + a subcritical core with the
criticality keff ~ 0.97…0.98) utilize the same "reactor"
neutron spectrum. Analysis of different areas of nuclear
power development shows the principal limitations of
the capacity of the traditional reactor and classical ac-
celerator driven (ADS) systems utilizing the neutron
fission spectrum to solve the global energy challenges.
Today, the use of neutron spectrum that is harder
than that of fission seems to a most viable option in
solving of the modern nuclear power problems. With
the purpose of practical implementation of this ap-
proach we developed a brand new scheme of electronu-
clear method that is based on the nuclear relativistic
technologies (NRT). The NRT scheme is aimed at the
formation of the hardest possible neutron spectrum in
deeply subcritical, quasi-infinite (with minimal leakage
of neutrons) reactor core due to, in particular, the use of
accelerated particles with energies of up to 10 GeV. It is
expected that such spectrum will allow cost- and envi-
ronmentally effective disposal of spent fuel assemblies
(FA) containing spent nuclear fuel (SNF) with simulta-
neous energy production as well as to "burn" waste ura-
nium and thorium for energy production. [2 - 4].
It should be noted that the suggestion to use the
NRT in the electronuclear method is based, among oth-
er things, on the experiments of the V.I. Yurevich –
R.M. Yakovlev [5] that were performed on the "classic"
electronuclear lead target with the diameter of 20 cm
and the length of 60 cm, at the energies of protons and
deuterons in the range of about 1 GeV up to ~ 3.7 GeV.
It was found that with the increase of the beam energy a
significant increase in the average energy of leakage
neutron, the kinetic energy of the leakage neutron and
the share of the primary proton energy going into kinet-
ic energy of the leakage neutron is observed.
This work was performed in the framework of the
international collaboration "Energy and Transmutation
of RAW" and is dedicated to research of neutron pro-
duction processes in the massive uranium target. The
main purposes of the collaboration were: determination
of optimum energy and type of accelerated particles; the
study of the processes of the neutron formation and the
spatial distribution of neutron spectra; determination of
dependence of the beam power amplification on energy
of the incident particles; the study of the effectiveness
of transmutation of a number of isotopes of spent nucle-
ar fuel; obtaining a set of experimental data for modify-
ing existing models and transport codes.
The main purposes of this work were:
- to obtain spatial distributions of density of radia-
tive capture reactions (the number of accumulating
239Pu nuclei) and density of 238U fissions in the volume
of the uranium target of the QUINTA assembly;
- to obtain spatial distribution of spectral indices;
- to determine the total number of 238U fissions and
total amount of 239Pu, accumulated in the volume of the
uranium target of the QUINTA assembly;
- to compare obtained experimental results as a
function of the energy of deuteron beam.

1. DESCRIPTION OF EXPERIMENT
The uranium target of the QUINTA assembly sur-
rounded by a lead blanket was irradiated by deuterons
with the energy of 1, 4, 8 GeV in the Nuclotron acceler-
ator. The target (Fig. 1) consists of 5 sections that were
made in the form of hexahedron filled by cylindrical
rods of natural metal uranium. Section No. 1 contains
54 uranium rods and has a central through-hole
Ø 80 mm for the beam input to the target. This was
made to reduce the leakage of neutrons from the target.
Sections No.'s 2…5 are structurally identical and con-
tain 61 uranium rods each. The total weight of uranium
in 5 sections of the target is ≈ 512 kg. The uranium tar-
get is placed inside a lead reflector with a thickness of
10 cm. Accelerated deuteron beam falls to the wall of
section No. 2 of the target through a square hole in the
lead reflector with the dimensions 15×15 cm and the
input window of section No. 1 and generates neutrons
and other particles, which in turn are the source of vari-
ous nuclear reactions with the formation of secondary
radiation. In order to obtain the spatial distribution of
the neutron flux and reactions caused by them in the
volume of uranium target different detectors that are
placed on 6 removable detector plates are used. The
detector plates are installed in the gaps between the sec-
tions of the uranium target, as well as on the front and
on the end face of the target (Z = 0, 123, 254, 385, 516,
647 mm). The spatial distributions of density of reac-
tions (n, f) and (n, γ) were studied using activation of
foils (29 pieces) of natural uranium (Ø 8 mm, thickness
1 mm) that were positioned on each detector plate in the
positions of R = -80, 0, 40, 80, 120 mm from the beam
axis.
Monitoring of the total intensity of deuteron beams
was carried out using standard method of activation of
aluminum foil by reaction 27Al(d,x)24Na. The cross sec-
tions of the reaction for the deuteron energies used were
determined using the method described in work [6] and
were: 16.8 mb (1 GeV), 14.6 mb (4 GeV), 14.0 mb
(8 GeV). Using these cross sections the following val-
ues of the total intensity of deuterons were obtained:
1.8(0.2)·1013 (1 GeV), 2.7(0.3)·1013 (4 GeV),
3.7(0.3)·1013 (8 GeV).
For comparison of the results that were obtained at
different deuteron energies it is necessary to recalculate
the coordinates for each irradiated uranium foil relative
to the real axis of the beam. For such recalculation it is
necessary to know the beam profile as well as its posi-
tion when it hits the target. Determination of the profile
and position of the beam was performed using the tech-
nique of solid-state track detectors [7, 8]. The target
sandwiches (size 40 40 mm) consisting of artificial
mica + lead foil radiator were installed at the beam in-
put. This type of track detector has high efficiency of
detection of fission fragments and eliminates the back-
ground from the recoil nuclei when it is exposed to neu-
tron fields with a hard spectrum.
After the end of irradiation the -spectra of irradiated
Al beam monitors and uranium foils were measured by
the high-purity germanium detectors -spectrometers.
The number of nuclei of different radioactive nuclides
produced throughout the time of irradiation was deter-
mined considering the following correction factors: the
factor associated with the accelerator stops and changes
in the beam intensity during irradiation; the factor that
takes into account self-absorption of γ-radiation detect-
ed in the sample, the factor that takes into account
changes of the geometry during the measurements; the
factor that takes into account the geometrical dimen-
sions of the sample, the factor that takes into account
the coincidences during γ-line registration.

The number of radioactive capture reactions of 238U
corresponds to the number 239Pu, that is formed as a
result of the 239U β-decay chain:
238U(n, )239U (23.54 min) β-
239Np (2.36 d) β- 239Pu.
Measurement of gamma-ray spectra of irradiated
foils was performed in 4 hours after the end of irradia-
tion (more than 10 half-lives of 239U) on the yield of γ-
line with energy of 277.6 keV (there are no contribution
from the γ-lines of other radionuclides) accompanying
the decay of 239Np.
The γ-lines of different fission fragments were iden-
tified in the measured γ-ray spectra of irradiated urani-
um foils. Those fission products with yields per fission
by neutrons close in a wide energy range (from fission
spectrum neutrons up to 22 MeV neutrons [9, 10]) were
used for determination of the number of 238U fission
reactions. The number of nuclear fissions was deter-
mined by averaging the results for the following frag-
ments (the yield per fission is given in parentheses):
97Zr (5.7%), 131I (3.6%), 133I (6.3%), 143Ce (4.3%).
2. RESULTS AND DISCUSSION

numbers of natU(n, γ)-reactions, natU(n, f)-reactions (per

and 8 GeV for three detector plates (Z = 0, 254,

Fig. 2. Radial distributions of density of numbers of natU(n, γ)-reactions, natU(n, f)-reactions (per 1 deuteron and
1 GeV of energy) over the volume of the target and spectral indices for deuteron energies of 1, 4 and 8 GeV
It should be noted that the type of the spatial distri-
butions of the number density of the uranium fission
reactions and the number of produced 239Pu nuclei per
unit of deuteron primary beam depends on the deuteron
energy: with the increase of primary deuteron energy
the density of number of uranium fission and number of
produced 239Pu nuclei is reduced in the near field to the
deuteron beam input at the target and at the same time
there is an increase in the number of uranium fission
and number of produced
239
Pu to the periphery of the
target. Spectral index (the ratio between the average
cross sections of neutron capture and uranium fission) is
most suitable for comparison with the results of calcula-
tions as it does not contain errors of deuteron flux defi-
nition. The spectral indices change from the axis of the
deuteron beam to the periphery of the uranium target
from about 0.4 to 2, indicating a softening of the neu-
tron spectrum, and do not depend on the energy of the
beam in the range of 1…8 GeV.
Figs. 3-4 shows the dependencies of values of num-
bers of uranium fissions and produced 239Pu, integrated
to a given radius R for each of the 5 sections (on the
left) and in the whole QUINTA target assembly (on the
right).
Each point on the left part shows the total number
of fissions or the number of (n, γ) reactions in a cylin-
drical volume of the corresponding radius R of this

metry of the considered spatial distributions relative to

Fig. 4. Dependence of number of fissions on radius R

for deuterons 1, 4 and 8 GeV (relative to the axis
of the deuteron beam)
One should note almost linear radial dependence of
the values of number of plutonium production and fis-
sion. It should be noted that such behavior indicated in
Figs. 3-4, with the growth of the transverse size of the
uranium target, should go to the plateau. This condition
corresponds to the condition of quasi-infinite target.
However, the existing size of the uranium target of the
QUINTA assembly is not enough for the quasi-infinite
target and it is impossible to estimate experimentally
what size is required for this. In addition, the behavior
of the curves in Figs. 3-4 indicates that a significant part
of neutrons escapes the the QUINTA target assembly.
Also based on the obtained data we can conclude that
for given sizes of uranium target of the QUINTA as-
sembly, for deuteron energies exceeding 1 GeV, it is
impossible to experimentally estimate (at least using the
activation technique) the required size of the uranium
target, satisfying the condition of its quasi-infinity and,
therefore, it is impossible to estimate the total number
of fissions and accumulated 239Pu nuclei for quasi-
infinite target. This requires the measurement of urani-
um targets of larger mass.
Table summarizes the integral numbers of 239Pu
production and
nat
U fission in the volume of the uranium
target of the QUINTA assembly per one deuteron and
1 GeV of initial energy, that were obtained by different
methods: the activation method, the method of solid-
state track detectors, as well as the calculated values
obtained using the MCNPX 2.7e program [11].

The table gives the results with two errors: statisti-
cal (~5%) and systematic (~11%). The systematic error
is mainly due to an error in the cross section of alumi-
num monitor reaction. The total number of neutron
captures and 238U fissions (per 1 deuteron and 1 GeV of
initial deuteron energy) in the volume of the uranium
target of the QUINTA assembly that were defined by
different methods, remains approximately constant
within the statistical errors for deuteron energies of
1…8 GeV.
CONCLUSIONS
The research of the spatial and energy distributions
of neutrons in the system "uranium target+lead blan-
ket" irradiated by deuterons with energy of 1, 4 and
8 GeV was performed. The measured distributions of
plutonium production and number of fission reactions
of uranium allowed to obtain the total amount of these
values, which increase proportionally to the deuteron
energy. A similar result was obtained by calculation
using the MCNPX 2.7e program and methods of solid-
state track detectors for the number of fissions. Starting
from 2014 JINR is planning to launch experiments on
target of depleted uranium with the weight of 21 tons.
The uranium target of the QUINTA assembly to a lim-
ited extent simulates the central part of the new target.
The developed methods and the obtained results will be
used in future experiments.
