This is Westinghouse's eVinci microreactor, a X MWe transportable unit using heat pipes for passive cooling, designed for 8+ years without refueling.

Pros: Compact and mobile for remote/off-grid use; reduces emissions vs. diesel; low maintenance with few moving parts; enhanced safety (no water/pressure risks); quick setup; reliable baseload power.

Cons: High upfront cost ($90-120M initially); produces more nuclear waste per energy output; HALEU fuel raises proliferation concerns; potential security risks from dispersed units; regulatory hurdles delay deployment.
