Nuclear criticality safety practitioners attempt to prevent nuclear criticality accidents by analyzing normal and credible abnormal conditions in fissile material operations and designing safe arrangements for the processing of fissile materials. A common practice is to apply a double contingency analysis to the operation in which two or more ...
In 2016, Senator Juan Ponce Enrile, a former defence secretary under the Marcos administration, claimed that the Bataan Nuclear Power Plant was intended to be used in a development of a nuclear weapons program. While he maintained that the facility's main purpose was for electricity generation he alleged that the nuclear power plant's second ...
The Philippine Nuclear Research Institute (PNRI) is a government agency under the Department of Science and Technology mandated to undertake research and development activities in the peaceful uses of nuclear energy, institute regulations on the said uses, and carry out the enforcement of said regulations to protect the health and safety of radiation workers and the general public.
The Philippines began building a nuclear generating plant, the Bataan Nuclear Power Plant, in the 1970s but it was never completed after questions were raised about its cost and safety, including ...
The Philippine Research Reactor-1 was built under the Atoms for Peace nuclear research exchange program of the United States. [1] The reactor which had its first criticality on August 26, 1963, [2] was built by U.S. firm General Atomics and was originally a 1 MW MTR-type open pool general-purpose reactor. [1]
Criticality accidents are divided into one of two categories: Process accidents, where controls in place to prevent any criticality are breached;; Reactor accidents, which occur due to operator errors or other unintended events (e.g., during maintenance or fuel loading) in locations intended to achieve or approach criticality, such as nuclear power plants, nuclear reactors, and nuclear ...
Monte Carlo N-Particle Transport (MCNP) [2] is a general-purpose, continuous-energy, generalized-geometry, time-dependent, Monte Carlo radiation transport code designed to track many particle types over broad ranges of energies and is developed by Los Alamos National Laboratory.
Criticality is the normal operating condition of a nuclear reactor, in which nuclear fuel sustains a fission chain reaction. A reactor achieves criticality (and is said to be critical) when each fission releases a sufficient number of neutrons to sustain an ongoing series of nuclear reactions.
