Treatment of waste water for removal of low levels of actinides, particularly plutonium, uranium, and americium, and hazardous metals has been and continues to be a challenge. This study evaluated the use of apatite and other natural materials for us

In this work, we derive from the transport equation the effectiveness factor used in the β eff calculation and show that, to a first approximation, it is equal to the ratio of two k -eigenvalues: one obtained using the total neutron spectrum, and th

In this work, we describe the concept of an equivalent fundamental-mode source, and we derive an expression for a factor, g∗ , that converts any arbitrary source distribution to its equivalent fundamental-mode source strength. We also present a new

Reflected reactors constitute one of the most important classes of nuclear reactors. Yet, experimental data clearly shows that the kinetic behavior of some types of reflected systems cannot be adequately characterized using the standard point kinetic

Naturally occurring dysprosium is attractive as a neutron detector because of its high thermal neutron capture cross section and high natural abundance. Neutron-induced transmutation of 164Dy results in production of stable isotopes of holmium and er

The central reactivity worth measurements performed in Lady Godiva were duplicated using TWODANT, a deterministic neutron transport code, and the 16-group Hansen-Roach cross-section library. The purpose of this work was to determine how well the Hans

The concept of detection of thermal neutrons using gadolinium oxide nanocrystals is explored. Gadolinium is an element with by far the highest thermal neutron capture cross section among all stable isotopes. Colloidal synthesis of Gd 2 O 3 nanocrysta

We propose a novel concept of optical detection of thermal neutrons in a passive device that exploits transmutation of Dy-164, a dominant, naturally occurring isotope of dysprosium, into a stable isotope of either holmium Ho-165 or erbium Er-166. Com
