What does PWR stand for?

Explanation:
PWR refers to a reactor design where the primary coolant is kept under high pressure to prevent boiling in the core, so heat is carried away by the water to a secondary loop where steam is generated for the turbine. This arrangement—high-pressure primary coolant and an indirect steam generation via a steam generator—is what characterizes a Pressurized Water Reactor. The other phrases aren’t standard reactor types and don’t describe this key feature of keeping the primary coolant under pressure to avoid boiling.
