Pavlovsk Bay is the home port of several PM-124 class (PM-80, PM-125, PM-133) service ships. These ships hold 1,680 spent fuel assemblies, including 118 damaged fuel assemblies on the PM-80. The PM-133, also known as TNT-16, was contaminated during rescue efforts that followed the 10 August 1985 incident during which the reactor of K-314, an Echo II (Project 675) SSN, caught fire and vented radiation in Chazhma Bay.[6,7,8] Two technical support ships also operate at the facility, the TNT-5 and TNT-27.[8,9,10]
