Determination of ultra-low level plutonium isotopes (239Pu, 240Pu) in environmental samples with high uranium.

open access: yesTalanta: The International Journal of Pure and Applied Analytical Chemistry, 2018
In order to measure trace plutonium and its isotopes ratio (240Pu/239Pu) in environmental samples with a high uranium, an analytical method was developed using radiochemical separation for separation of plutonium from matrix and interfering elements ...

Detection of Anomalous Reactor Activity Using Antineutrino Count Rate Evolution Over the Course of a Reactor Cycle [PDF]

open access: yes, 2010
This paper analyzes the sensitivity of antineutrino count rate measurements to changes in the fissile content of civil power reactors. Such measurements may be useful in IAEA reactor safeguards applications. We introduce a hypothesis testing procedure to

Level, distribution and sources of plutonium in the coastal areas of China.

open access: yesChemosphere, 2019
Plutonium is an important radioactive element in view of its biological toxicity and environmental impact. The two most important isotopes of plutonium, 239Pu and 240Pu, in the surface soil from the coastal area of China were determined using ...

On the possibility to improve mixed uranium-plutonium fuel in fast reactors [PDF]

open access: yesNuclear Energy and Technology, 2020
Accumulation of plutonium extracted from the spent nuclear fuel (SNF) of light water reactors is one of the central problems in nuclear power. To reduce out-of-the-reactor Pu inventory, leading nuclear power countries (France, Japan) use plutonium in ...

Plutonium production and particles incorporation into the human body.

open access: yesJournal of Environmental Radioactivity, 2019
Plutonium is one of the most toxic radioactive substances known. The isotope 239Pu gained attention when it had become known as a potential explosive material for atomic bombs.

Nature of non-magnetic strongly-correlated state in delta-plutonium [PDF]

open access: yes, 2005
Ab-initio relativistic dynamical mean-field theory is applied to resolve the long-standing controversy between theory and experiment in the "simple" face-centered cubic phase of plutonium called delta-Pu.

Sensitivity coefficients of the neutron and physical reactor parameters to the fuel inventory parameters

open access: yesNuclear Energy and Technology, 2015
Required properties of fast reactor core with nitride fuel are reached only if the fuel it is loaded with is plutonium-based and has strictly determined (equilibrium) isotopic composition and strictly determined plutonium mass fraction (plutonium ...

Determination of Plutonium Present in Highly Radioactive Irradiated Fuel Solution by Spectrophotometric Method

open access: yesNuclear Engineering and Technology, 2016
A simple and rapid spectrophotometric method has been developed to enable the determination of plutonium concentration in an irradiated fuel solution in the presence of all fission products.

Terrorism and maritime shipment of nuclear material [PDF]

open access: yes, 2007
Opponents of the nuclear industry often claim that material in transit is vulnerable to attack by terrorist groups who might seek to take the cargo and make a bomb, or otherwise cause a radiological incident.

Insights into the sonochemical synthesis and properties of salt-free intrinsic plutonium colloids

open access: yesScientific Reports, 2017
Fundamental knowledge on intrinsic plutonium colloids is important for the prediction of plutonium behaviour in the geosphere and in engineered systems. The first synthetic route to obtain salt-free intrinsic plutonium colloids by ultrasonic treatment of
