Phrase: S5W reactor design | Statement: [HMS Dreadnought, nuclearReactorType, S5W reactor design]

Target entity: S5W reactor design
Context triple: [HMS Dreadnought, nuclearReactorType, S5W reactor design]

• A. S2W nuclear reactor
  The S2W nuclear reactor was an early U.S. Navy pressurized water reactor design that powered the world’s first operational nuclear-powered submarine, USS Nautilus.
• B. System 80 nuclear reactor design
  The System 80 nuclear reactor design is a standardized pressurized water reactor model known for its advanced safety features and use in commercial power plants, originally created by Combustion Engineering.
• C. SRS L Reactor
  SRS L Reactor is a former production nuclear reactor at the Savannah River Site in South Carolina that was used primarily for generating materials for nuclear weapons.
• D. ZEEP reactor
  The ZEEP reactor was a small Canadian research nuclear reactor that played a key role in early nuclear physics experiments and the development of Canada's nuclear energy program.
• E. IBR-2 reactor
  The IBR-2 reactor is a fast pulsed research nuclear reactor used primarily for neutron scattering experiments in condensed matter physics and materials science.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

Generate a one-sentence description of the target entity. 
You are given a context triple in the form (subject, predicate, object), where the object is the target entity.
