Sensitivity studies of PWR MOX fuel management to the plutonium initial vector using Artificial Neural Networks [PDF]

EPJ Web of Conferences
This paper presents new metamodels based on artificial neural networks trained on full core 3D depletion simulations performed with APOLLO2 and CRONOS2. They are used to estimate the irradiation cycle length, discharge burn-up of each fuel assembly type ...

Assessing the applicability of a special model of plutonium behavior in presence of chelates in cases of wound intake of industrial compounds of plutonium in the FSUE Mayak PA workers

Радиационная гигиена
In cases of intake of higher levels of plutonium, a chelate diethylenetriaminepentaacetic acid is used to enhance the elimination and reduce deposition rate in the organs of major deposit in the form of calcium compound Ca-DTPA (pentacinum). To interpret

Research and application of plutonium inventory monitoring system for solution systems

International Journal of Advanced Nuclear Reactor Design and Technology
In order to monitor the plutonium inventory of the solution system, the “point model” equations originated from the nuclear safeguard for plutonium monitoring were improved to make it applicable to the solution system.

Comparative analysis of inductively coupled plasma mass spectrometry and alpha spectrometry methods to measure plutonium activity in biosubstrates

Радиационная гигиена
Currently, the most common methods to measure the activity of transuranium elements in biological samples are alpha radiometry and alpha spectrometry. Of these, alpha spectrometry is the most sensitive and selective method.

Interaction Mechanisms Between Pu(Ⅳ), Colloid, and Immobile Media (Granite): Experiments, Surface Complexation and DLVO Potential

He huaxue yu fangshe huaxue
In order to accurately simulate the large-scale migration of plutonium in groundwater(a three-phase system), it is necessary to understand the interaction mechanisms between plutonium(Ⅳ), natural colloid, and granite(immobile media).
