The Radiochemistry of Nuclear Power Plants with Light Water ...
However, because of the risks involved in the application of higher lithium
concentrations, this kind of treatment has been widely abandoned. The dilemma
in using boric acid as a soluble neutron poison is caused by the fact that the
effective ...

Research Reactor Aluminum Spent Fuel:: Treatment Options for ...
It appears that a stronger neutron poison will be required (e.g., Gd for high
enriched fuel) than for low enriched fuel (e.g., borated stainless steel). The
relative dilution rates of fuel versus neutron poison over a long period pose a
vexing ...

Essays in Nuclear Astrophysics
Further, the 14C would /3 decay in due course, to regenerate the 14N neutron
poison. The usefulness of 13C(a,n)16O as an important neutron source was
restored by a suggestion of Schwarz- schild and Harm (1967), and Sanders (
1967).
Charles A. Barnes, Donald D. Clayton, D. N. Schramm, 1982

Plasma Science and the Environment
These poisons dominate the eventual performance of any nuclear system where
high material burnup is an objective. ln the case of a solid-fuel system, fuel must
be removed, reprocessed, and reconstituted to achieve neutron-poison removal.
Wallace M. Manheimer, Linda E. Sugiyama, Thomas Howard Stix, 1997

Radioactive Elements—Advances in Research and Application: ...
Incorporation of neutron poisons is preferably homogeneous throughout the fuel
and is often accomplished by blending neutron poison powders in the matrix.
Because of several reasons, eg. the higher uranium loadings required in the LEU
...

Nuclear Systems: Elements Of Thermal Design
These neutron-poison rods also may be employed to compensate long-term
reactivity changes. Following large insertion at the beginning of core lifetime, they
are gradually withdrawn as fuel-burnup, transmutation, and fission- product
effects ...

The Fundamentals of Nuclear Power Generation: Questions and ...
What is a neutron poison? A neutron poison is a substance with a large neutron
absorption cross section in applications are inserted into some types of reactors
in order to lower the high reactivity of their initial fresh fuel load in the reactor core
.
When all the neutron-absorbing faces of the control drums are turned inward, the
neutron poison absorbs neutrons that would otherwise be reflected back into the
reactor to cause new fission reactions. To start the nuclear rocket, motors slowly ...

Nuclear Risks and Preparedness: Updated First Edition
When it does not, it acts as a neutron poison. Reactor operators can manipulate
the total amount of poisons in the reactor by adjusting the position ofthe control
rods. Also, in a pressurized water reactor, the operator can adjust the amount of ...

Nuclear Physics of Stars
Detailed calculations have shown that, independent of metallicity, 12C does in
fact not represent an important neutron poison because the lost neutrons are
recycled, and thus recovered, by the sequence 12C(n,γ)13C(α,n)16O. The
situation is ...
