THE HOMOGENEOUS SUSPENSION REACTOR PROJECT, by Prof.
JJ. Went
This introductory article first of all answers the question why the development of a
suspension reactor is being undertaken, and then explains briefly what research has
to be carried out. It concludes with a succinct description of the KEMA Suspension
Test Reactor (KSTR).
PHYSICAL ASPECTS OF THE HOMOGENEOUS SUSPENSION REACTOR
PROJECT, by Dr. J.A.H. Kersten 15
In this article, a brief description is given of the sub-critical reactor. This is followed
by a recapitulation of the principal results obtained by reactor-physics measurements.
During the investigations it was found that by the same means important information
could be derived concerning the hydrodynamics in and outside the reactor vessel and
the colloid-chemical properties of the suspension.
CHEMICAL ASPECTS OF THE HOMOGENEOUS SUSPENSION REACTOR
PROJECT, by Ir. M.E.A. Hermans 33
The chemical problems that arise out of the development of the homogeneous sus­
pension reactor are both numerous and extremely varied. For the survey given in
this article, a selection has been made from the subjects studied which illustrates the
typical problems raised by the suspension reactor. This selection comprises fuel
preparation, radiation-resistance of the fuel, colloid-chemical stability of the suspension,
UO: range of fission products, erosivity of the fuel suspension, removal of fission
products and caking.
ENGINEERING ACTIVITIES IN THE SUSPENSION REACTOR PROJECT,
by Ir. H. Wolf 49
In the previous articles, the KEMA Project for the development of a homogeneous
suspension reactor was described as regards its general set-up. The present article
deals more fully with the engineering aspects. A survey is given of the research
necessary for the design, construction and operation of the KSTR.
THE KEMA SUSPENSION TEST REACTOR (KSTR) INSTRUMENTATION
SYSTEM, by Dr. J.J. van Zolingen 65
In this article of the series on the KEMA Suspension Test Reactor (KSTR), attention
is devoted to the extensive instrumentation considered necessary for the reactor. In
addition to the equipment required for normal operating purposes, provision must be
made for extremely accurate measurements. There is also a description of the instru­
mentation needed for incidental. Page
PROTECTION AGAINST RADIATION EMITTED BY THE KEMA SUS­
PENSION TEST REACTOR (KSTR), by Drs. Hub. Wijker 79
For the protection of individuals against ionizing radiations from the KSTR, the
following points have to he born in mind:
a) The placing of thermal shields between the reactor and the nearby walls of the
reactor hall.
b) The placing of biological shields between the radiation sources and the parts of
the hall which have to be accessible.
c) The diffusion of radioactive gases from the stack.
d) The scaling-up ofe fission products.
e) The processing of liquid and solid radioactive waste. The Homogeneous Suspension Reactor Project
by Prof. Dr. J.J. WENT
The periodical "Atoomenergie en haar Toepassingen" has published a series of
articles on development work which has already been carried out and the programme for
the immediate future concerning a homogeneous suspension reactor, i.e. a reactor using a
suspension of fissile materials in water. The present publication is a translation of the
orginal Dutch articles.
The studies are being carried out at the N.V. Kenia laboratories Arnhem, Nether­
lands under a scheme for collaboration between EURATOM, RCN and KEMA. Under this
scheme EURATOM and RCN are to provide personnel as well as financial assistance.
Since the purpose of these articles is to convey an idea of the problems involved in
the use of suspensions in nuclear reactors, an account is also given here of work covering
the results of the activities of all those engaged on the project. The articles are written
by departmental heads who must be considered as representing the department as a
whole.
Why a homogeneous suspension reactor ?
Before presenting the research in progress at Arnhem, it is worthwhile explaining
why the homogeneous suspension reactor is being studied at all.
When the various types of nuclear reactors are compared from the standpoint of the
type and form of the fuel and the various possible moderator materials, the coolant and
the structural parts to ha used, the temperatures to be attained, the control mechanism to
be employed, the extent to which use is to be made of fission neutrons possessing a high
kinetic energy, or, on the other hand, of neutrons of low kinetic energy slowed down by
a moderator (this can differ by a factor of 10s) it is by no means surprising that more than
1,000 different reactor types were at one time considered to be possible. Although many
of them can be immediately ruled out as impracticable it cannot yet be determined which
type(s) will offer the best possibilities for the future. Different types will therefore have
to be examined. Therefore we shall go into our arguments for considering it advisable,
and even desirable, to proceed with the development of a homogeneous suspension reactor,
