چکیده

M.A. Lone, W.J. Edwards and R. Collins AECL Research, Chalk River Laboratories Chalk River, Ontario, Canada. KOJ lJO (613)-584-3311 Thermal neutron capture cross section of the 9%r(n,y)91 Sr reaction was measured in a D20 moderated neutron flux with an activation technique. The sensitivity of the measurement was improved by using chemical separation of 90Y from 91 Sr for reduction of the intense bremsstrahlung background from beta decay of Y. The value obtained for the cross section is 9.7* 0.7 mb.

A Feasibility Study of the SLOWPOKE-2 Reactor as a Neutron Source for Boron Neutron Cancer Treatment

Over the past decade, there has been a continued interest in the development of Boron Neutron Capture Therapy (BNCT) as a potential treatment for cancerous tumours and especially certain brain tumours. In this method, advantage is taken of the nuclear properties of certain elements such as boron. A special boron carrier drug, designed to be selectively taken up by the cancer cells, is administe...

Probing Neutrino Magnetic Moments at Underground Detectors with Artificial Neutrino Sources

Neutrino-electron scattering can be used to probe neutrino electromagnetic properties at low-threshold underground detectors with good angular and recoil electron energy resolution. We propose to do this using a number of artificial neutrino and anti-neutrino sources such as 51Cr24 and 90Sr−Y . The neutrino flux is known to within one percent, in contrast to the reactor case and one can reach l...

Computing Atomic Density Changes of Material Composition in Operation of the Nuclear Reactor Core

The present work investigates an appropriate way to calculate the 1700 atomic density changes in the reactor operations. To automate this procedure, a computer program has been designed by C#. This program suggests a way to solve this problem which is based on the solution system of differential equations (Bitman) that it is designed according to Runge-Kutta Fehlberg method. The designed softwa...

Measurement of 90Sr by Preconcentration/Matrix Separation and Reaction Cell ICP-MS

The tsunami after the 2011 Tohoku earthquake devastated a vast coastal area of eastern Japan. The Fukushima Daiichi nuclear reactor suffered meltdowns of its uranium fuel rods, resulting in the release of radioactive isotopes. One of the most environmentally critical isotopes released was strontium-90 (90Sr), a fission product of uranium and plutonium which has a half-life of 29 years, thus rem...

Flux-limited Diffusion Coefficients in Reactor Physics Applications

Flux-limited diffusion theory has been successfully applied to problems in radiative transfer and radiation hydrodynamics, but its relevance to reactor physics has not yet been explored. The current investigation compares the performance of a flux-limited diffusion coefficient against the traditionally defined transport cross section. A one-dimensional BWR benchmark problem is examined at both ...
