SEOUL—Satellite imagery suggests recent flooding in North Korea may have damaged pump houses connected to the country’s main nuclear facility, a U.S.-based think-tank said on Thursday.

Analysts at 38 North, a website that monitors North Korea, said commercial satellite imagery from August 6-11 showed how vulnerable the Yongbyon Nuclear Scientific Research Center’s nuclear reactor cooling systems are to extreme weather events.
