  2. Scram - Wikipedia

    en.wikipedia.org/wiki/Scram

    SCRAM button at the Experimental Breeder Reactor I in Idaho. Sometimes the switch will have a flip cover to prevent inadvertent operation. A scram or SCRAM is an emergency shutdown of a nuclear reactor effected by immediately terminating the fission reaction.

  3. Reactor protection system - Wikipedia

    en.wikipedia.org/wiki/Reactor_protection_system

    A reactor protection system (RPS) is a set of nuclear safety and security components in a nuclear power plant designed to safely shut down the reactor and prevent the release of radioactive materials. The system can "trip" automatically (initiating a scram), or it can be tripped by the operators. Trips occur when the parameters meet or exceed ...

  4. Shutdown (nuclear reactor) - Wikipedia

    en.wikipedia.org/wiki/Shutdown_(nuclear_reactor)

    Shutdown is the state of a nuclear reactor when the fission reaction is slowed significantly or halted completely. Different nuclear reactor designs have different definitions for what "shutdown" means, but it typically means that the reactor is not producing a measurable amount of electricity or heat and is in a stable condition with very low reactivity.

  5. Nuclear organization - Wikipedia

    en.wikipedia.org/wiki/Nuclear_Organization

    Moreover, nuclear organization can play a role in establishing cell identity. Cells within an organism have near identical nucleic acid sequences, but often exhibit different phenotypes. One way in which this individuality occurs is through changes in genome architecture, which can alter the expression of different sets of genes. [5]

  6. Nuclear bodies - Wikipedia

    en.wikipedia.org/wiki/Nuclear_bodies

    ND stands for nuclear domain, and 10 refers to the number of dots seen. [3] Additionally, a nuclear body subtype is a clastosome suggested to be a site of protein degradation. [4] While biomolecular condensate is a term often used interchangeably with nuclear bodies, the term "condensates" implies the thermodynamic properties of the body are ...

  7. Nuclear envelope - Wikipedia

    en.wikipedia.org/wiki/Nuclear_envelope

    The nuclear envelope, also known as the nuclear membrane, [1] [a] is made up of two lipid bilayer membranes that in eukaryotic cells surround the nucleus, which encloses the genetic material. The nuclear envelope consists of two lipid bilayer membranes: an inner nuclear membrane and an outer nuclear membrane. [ 4 ]

  8. Nuclear transport - Wikipedia

    en.wikipedia.org/wiki/Nuclear_transport

    Nuclear transport refers to the mechanisms by which molecules move across the nuclear membrane of a cell. The entry and exit of large molecules from the cell nucleus ...

  9. Nucleotide excision repair - Wikipedia

    en.wikipedia.org/wiki/Nucleotide_excision_repair

    Replication factor C loads the Proliferating Cell Nuclear Antigen (PCNA) onto the DNA strand. This allows DNA polymerases implicated in repair (δ, ε and/or κ) to copy the undamaged strand via translocation. DNA ligase I and Flap endonuclease 1 or the Ligase-III-XRCC1 complex seal the nicks to complete NER.
