Perspectives of mathematical modeling usage for neutron radiography set ups development are considered.
Results of the calculation of neutron passing through plane polyethylene layer are given.
PACS: 61.20.ja
Work on neutron radiography (NR) methods
development was carried out in KIPT in 1999-2002
years. At this time world experience of NR application
was studied, fields of its possible application, most
perspective for Ukraine, was determined. Technical
suggestions of such linac based set up creation was
developed, technical requirements for such set up was
worked out, different variants of its realization was
considered, design drawings of NR set up module was
developed, neutron flux diagnostics methods and NR
images visualization by film method were worked out.
Application of neutron radiography method is most
perspective in following branches of industry and science:
– atomic science – control of physics states (foliating,
structure defects, fission substances flux changing, hydric
substances and emptiness including), checking of
irradiated fuel arrays, enrichment and sizes of fuel rod
arrays with new and irradiated fuel, fuel rod arrays quality
control, studying of nuclear fuel characteristics at different
stages of new fuel elements models development, control
of containers with radioactive wastes;
– space industry – control of subassemblies,
consisting of isolation, plastic components, agglutinated
units; pyrotechnic elements state (detonating devices,
blow-out devices, gaseous charges and so on), moisture
and corrosion detection, precision defectoscopy of the
most important units, etc.;
– defense – control of blow-out charges, control of
fuel state in solid-fuel rockets, control of subassemblies,
engines construction optimization;
– aircraft technics – latent corrosion in aluminum
constructions, water in hollows, latent defects in aircraft
turbines, dynamics of liquid fluxes in aircraft engines etc.;
– automobile industry – dynamics of liquid fluxes in
engines, control of moulds for wheel casting, etc.;
– turbine construction (control of turbine blades quality);
– science of materials – addition elements distribution,
defectoscopy, including of hydric elements, other
substances etc.;
– chemical and petrochemical industry – gaseous
and liquid phases visualization, control of encapsulation
quality etc.;
– ceramic industry(searching for cracks);
– heat transfer – visualization of gaseous and liquid
phases action;
– geology – rock porosity, layers in sedimentary
rocks, search for track quantities of oil etc.
First of all in Ukraine neutron radiography
technology can be used for control of new fuel rod
arrays model quality at their experimental operation
(particularly, at realization of project "Ukrainian nuclear
fuel", South-Ukrainian nuclear power station), during
the development of new engine models, first of all
aircraft ("Motor Sich" plant in Zaporozhye), for
reliability increasing of space technics ("Uzhmash"
plant in Dnepropetrovsk), for searching for defects and
homogeneities in turbine blades ("Turboatom" plant in
Kharkov) etc.
Gamma-radiography is known to be applied with
great success for control of homogeneous objects [1]. At
the same time neutron radiography gives large
possibilities for inspection of the products of complex
composition with hydric or other elements with large
neutron interaction cross-sections [1]. Hence, at highly-
precise linear accelerator it is principally possible to
unite these methods and to obtain new possibilities of
undestroying control of different products.
Researches and developments carried out in KIPT
prepared the basis for experimental NR set up model
based on linac. Such model is necessary for NR method
optimization. It can be also used for solving of some
above mentioned problems and also for practical
demonstration of NR possibilities to potential
customers. During the development it is necessary to
optimize different units of NR set up (photo-neutron
target, moderator, neutron beam generating system,
photons and neutrons diagnostics system, modern
system of image visualization, etc.). Optimization by
experimental methods is very expensive and takes a
long time. So it is necessary to develop mathematical
model of NR set up and with its help determine required
optimal parameters.
Reliability of obtained results will be checked by
comparing of calculated and experimental results.
Variety of tasks, that can be solved with NR usage,
can require different types of primary neutron sources
(linac, neutron generator, isotope sources). That's why
mathematical model will be also used for optimal NR
set up for concrete tasks and conditions of potential
customers.
So for NR set up development first of all it is
necessary to develop programs, which simulate photons
and especially neutron interaction with matter. These
programs may be based on such well-known program-

function of plane depth Z for initial energy 2 MeV and
angles θ equal 0° (a), 30° (b), 45° (c)
packages as GEANT3, GEANT4 and MCNP. Now
many scientific departments in NSC KIPT have large
experience of dealing with GEANT3, GEANT4 is
studied and work with MCNP is planned.
As first step in mathematical modeling [2] of
neutron interaction with matter we studied neutron
passing through plane polyethylene layer. Monte-Carlo
method and data on neutron cross-sections from [3]
were used for solving this task. We took into account
capture and elastic scattering because other processes
have considerably less cross-sections. For thermal
neutrons kinetic equation in diffusion approximation
was solved [4].
Calculations have been carried out for parallel
monoenergetic neutron beam with initial energy 2 MeV
and angles θ between beam direction and normal to
plane equals to 0°, 15°, 30°, 45°. As the results of these
calculation we obtained thermal neutron sources
distribution in polyethylene plane of 5 cm thickness
(Fig. 1) and neutron spectrum after passing through
polyethylene plane at different angles θ (Fig. 2).
Obtained distributions are in good agreement with
existing data [5].
So from obtained rerults one can see that in NSC
KIPT works on realization of the above mentioned
program on mathematical modeling of neutron
radiography set ups are carried out.
