View source for VM reactor

The VM reactor ([[Russian language|Russian:]] '''реактор ВМ''') is type of various series of [[nuclear fission|nuclear]] [[pressurized water reactor]]s (PWR). They were used singly or in pairs to power the [[Soviet Navy]]'s [[submarine]]s. 

It was developed by [http://www.nikiet.ru/ NIKIET].

== Series ==

* The ''VM-A reactor'' was the [[nuclear fission]] [[nuclear reactor|reactor]] used in pairs to power the [[Soviet Navy]]'s Project 658 and 701 ({{sclass2|Hotel|submarine|5}}), Project 659 and 675 ({{sclass2|Echo|submarine|5}}), and Project 627 Кит ({{sclass2|November|submarine|5}}) first-generation submarines. It was a [[pressurized water reactor]] (PWR), using 21%<ref>{{cite web|title=История атомных реакторов / ВМ-А|url=https://www.biblioatom.ru/core-systems/nuclear-reactors/vm-a/|website=www.biblioatom.ru|accessdate=2025-06-27|lang=ru}}</ref> [[enriched uranium|enriched]] [[uranium-235]] fuel to produce {{cvt|70|MW|lk=on}} of power.  This is the reactor that powered {{ship|Soviet submarine|K-19||2}}. 
* The ''VM-4 reactor'' is a nuclear fission reactor using 20% enriched uranium-235 fuel to produce {{cvt|70|-|90|MW}} of power. It is used:
** singly to power the Project 670 Скат and Чайка-Б ({{sclass2|Charlie|submarine|5}}) submarines
** in pairs to power the Project 671 Ёрш and Щука ({{sclass2|Victor|submarine|5}}), Project 667 Мурена, Кальмар, and Дельфин ({{sclass2|Delta|submarine|5}}), and Project 667 Навага, Налим, Груша, and Андромеда ({{sclass2|Yankee|submarine|5}}) second-generation submarines.  
* The ''VM-5 reactor'' was the nuclear fission reactor used in a pair to power the Soviet Navy's Project 661 Анчар - Anchar ({{sclass2|Papa|submarine|5}}) second-generation submarine [[Soviet submarine K-222|K-222]]. It was a pressurized water reactor (PWR) using enriched uranium-235 fuel to produce {{cvt|177|MW}} of power.
