US nuclear reactor shielding.

08-09-10, 06:16 PM

The containment vessel consists of a verticle containment vessel of 5.5 meter diameter, between two water-tight bulkheads. The control rod drive is situated in a cupola which rests above the reactor chamber. The chamber can withstand a pressure of 15+ atmospheres.

The secondary shielding consists of concrete, lead, and polethyleane positioned toward the top of the containment area. Water, by its nature, contains any nuclear escape to the surrounding area.

A pre-stressed concrete wall of 122 cm surrounds the lower portion of containment. This wall rests upon a HTS cushion. A section of 15.2 cm lead obsorbs the gamma radiation. 15.2 cm of polethyleane is used to slow neutrons. Any space between lead plates is filled with lead wool.

Yes, and?

Also, all that clearly refers to a specific type of reactor, the setup would probably be different for different reactor types.

Just trying to spread the information. Julian Assange has opened the gin's bottle.

The primary shielding is provided by a water tank, which encapsulates the pressure vessel, surrounded by lead.

Yes, we know how google works, thank you.

Did you know that the NR-1 had no aft reactor shielding. Radiation containment was provided by a ballast tank filled with 12 feet of water since due to the small size of the NR-1 full shielding would have destabilized the submarine.

Did you know that any part of the submarine reactor which is below water is considered safe for the general public? See my original post.

Is that secret info?

It isn't of course but it shows how foolish some can be.
