Nondestructive Assay Measurements Using the RPI Lead Slowing-Down Spectrometer
The use of a lead slowing-down spectrometer (LSDS) is considered as a possible option for nondestructive assay of fissile material of used nuclear fuel. The primary objective is to quantify fissile isotopes, particularly 239Pu and 235U, via a direct measurement distinguishing them through their characteristic fission spectra in the LSDS. In this paper, we present several assay measurements perf...
متن کاملFission Physics and Cross Section Measurements with a Lead Slowing down Spectrometer
A Lead Slowing Down Spectrometer (LSDS) provides a high neutron flux environment that enables measurements of small samples (∼μg) or samples with small cross sections (tens of μb). The LSDS at Rensselaer Polytechnic Institute (RPI) was previously used for fission cross section measurements and for studies of methods for assay of used nuclear fuel. The effective energy range for the LSDS is 0.1 ...

متن کاملFission fragment mass and energy distributions as a function of incident neutron energy measured in a lead slowing-down spectrometer
A new method of measuring fission fragment mass and energy distributions as a function of incident neutron energy in the range from below 0.1 eV to 1 keV has been developed. The method involves placing a double-sided Frisch-gridded fission chamber in Rensselaer Polytechnic Institute’s lead slowing-down spectrometer (LSDS). The high neutron flux of the LSDS allows for the measurement of the ener...
متن کاملCross - section measurements for 239 Pu ( n , f ) and 6 Li ( n , a ) with a lead slowing - down spectrometer
We present fission cross-section measurements with 10ng of Pu performed using the LANSCE Lead Slowing-Down Spectrometer. Results of Liðn; aÞ measurements with a sample size of 760 ng of Li are also reported. This technical achievement demonstrates the feasibility of measuring neutron-induced fission cross-section on samples with 10 ng of fissile actinides that are available on ultra-small quant...
