    More than 30 people were over-exposed to radiation when the starboard reactor cooling system failed and the reactor temp rose uncontrollably. Emergency repairs ordered by the captain successfully cooled the reactor and avoided meltdown, but exposed the workers to high levels of radiation. [17] 8 Radiation accident in Morocco: 1984 March

  3. Criticality accident - Wikipedia

    en.wikipedia.org/wiki/Criticality_accident

    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 ...

    Globally, there have been at least 99 (civilian and military) recorded nuclear power plant accidents from 1952 to 2009 (defined as incidents that either resulted in the loss of human life or more than US$50,000 of property damage, the amount the US federal government uses to define nuclear energy accidents that must be reported), totaling US$20.5 billion in property damages.

    Step changes in reactor coolant leakage can be detected with moving filter media to satisfy the quantitative requirements of USNRC Regulatory Guide 1.45. [See description for US Patent Number 5343046 (1994).] The mathematical method is highly detailed and it focuses on time-dependent viewable collected activity, rather than concentration, as f(t).

    They developed chemical separation and radiation measurement techniques on terrestrial radioactive substances. During the twenty years that followed 1897 the concepts of radionuclides was born. [ 1 ] Since Curie's time, applications of radioanalytical chemistry have proliferated.

  7. Radiation hardening - Wikipedia

    en.wikipedia.org/wiki/Radiation_hardening

    Radiation hardening is the process of making electronic components and circuits resistant to damage or malfunction caused by high levels of ionizing radiation (particle radiation and high-energy electromagnetic radiation), [1] especially for environments in outer space (especially beyond low Earth orbit), around nuclear reactors and particle accelerators, or during nuclear accidents or nuclear ...

  8. Nuclear reactor safety system - Wikipedia

    en.wikipedia.org/wiki/Nuclear_reactor_safety_system

    In most reactors it takes the form of a sealed metallic or ceramic layer. It also serves to trap fission products, especially those that are gaseous at the reactor's operating temperature, such as krypton, xenon and iodine. Cladding does not constitute shielding, and must be developed such that it absorbs as little radiation as possible.

  9. Core damage frequency - Wikipedia

    en.wikipedia.org/wiki/Core_damage_frequency

    This risk analysis allows decision making of any changes within a nuclear power plant in accordance with legislation, safety margins, and performance strategies. A 2003 study commissioned by the European Commission remarked that "core damage frequencies of 5 × 10 −5 [per reactor-year] are a common result" or in other words, one core damage ...
