Some of the scuttlebutt we used to hear in the navy was that the navy went out on a limb in a humanitarian effort to help the Soviets with reactor safety issues during the cold war. I do not how factual this is but that was the buzz back then.

Twenty die on Russian boat
 

At least 20 people died Saturday when a fire safety system malfunctioned on a Russian submarine (Akula class). freon gas, used to stop fires, killed twenty one persons on board. The boat returned to base on it's own power.

wild bill

Foolish design
 

Freon is bad stuff it displaces Oxygen in your lungs and you are a dead man - you can not purge your lungs from it - that is one foolish design - we freak when we have a minor leak from one of our systems.

that was the Akula II that Russia was lending to India, right?

Already has been posted here:

also it got more information about the incident :yep:

As I posted somewhere else there is much safer extinguishing agents available.

Freon was commonly used as a referigerant in air conditioning systems. Its use was banned in the US when fears of it depleting the ozone layer were expressed. Freon was never used as an extinguishing agent to my knowledge. In fact I believe the article may have misspoke mistaking Freon for Halon.

A more common agent was Halon, its use has also been banned for 'new' installations. It was in common use for computer rooms where the use of water would be catastrophic. However it had real safety issues as you can see from this accident.

As I said its use is now banned and it is to be removed from any existing installations if you spend 10 cents on remodeling. The alternatives while safer are more expensive.

Here is a lengthy article on the subject http://www.halcyon.com/NAFED/HTML/Halonalt.html

Actually, it is probably Freon according to Romanov (Fire at Sea). They apparently bought the stuff from Japan, and they presumably used the stock (yeah, if you are the Russian Navy, you would be spending your very finite rubles on more expensive fire-fighting gas...)

Poor guys. People who served in our navy say that most accidents usually happen on the test runs before a vessel comes into comission. Especially on subs - because even in normal situation a lot depends on discipline and skills of crew, but when unfit ship in sea is overcrowded with civilian personnel who doesn't have much notion of sea ways and sub service - beware for the trouble...
As for Freon - our industry doesen't produce it since they've signed an agreement for Environment Care - but there is a lot of it in stock and an agreement doesn't forbid to use previously produced Freon. And as Nerpa is of the old design - probably they've decided not to change the project and to use the system with the stocked gas.
Sad anyway...

Inquiry panel rules accident cause as human error
 

In this article today:

Didn't take long to lay the blame.

To be fair, if this is true, this Grobov deserves more than seven years.

Manslaughter, 20 guys
20 more injured
Sabotage to equipment
Harmed Russian prestige and pride (incalculable national security interest) - since the world compartmentalizes Western accidents and generalizes Russian ones).

Roasting him alive in a cerematorium is too kind a punishment ... if he did it, of course.
