Exactly.

Some "pipe bomb" . . . .From AP:Per BATFE, it was a ". . . galvanized pipe that contained suspicious residue." Given the mindset of some of these "security personnel" (think the drones of the TSA for one example), this could have been ANY organic substance or even metal filings. And not very much of it, at that.

"An" answer? Definitely! There's not much you can't do by some means of explosion.

I will make sure and research then cite all my one-off posts just for you, Richard Dean Anderson.

Where English is "quiet" obviously a challenge for you, I apologize for using big words. Let's try again . . . although I do understand the left's allergic reaction to logic, so I don't have much hope for you. Your boy WaterDragon leaped to accuse the media of racism because the name wasn't given in the initial reports. This is normal; breaking stories have bits and pieces of facts which come out over time. According to the second wave of reports, the "bomb" had "residues" in it. A day goes by and now it has NOTHING explosive in it. So, what do we have here? A piece of pipe, capped, with some residue in it. It was not worth the time involved to address WaterDragon's feeble attempt at sarcasm where it is so obviously irrational. Hope you enjoyed your shower - did Mommy let you wash your little duckies, too?

"containment wasnt on the reactor because they were cycling fuel to make weapons grade plutonium"You don't know what you're talking about."they also used carbon as a moderator"Wrong again, Chernobyl was graphite-moderated.

Yes and no. The design was horrible. Due to the fact they wanted to use natural uranium, heavy water and graphite were used to moderate. Due to the design there was a the large positive void coefficient, which basically means that when the reactor gets hotter, the reaction rate increases and vice versa. Normally this ok (like in CADNU reactors), when the void coefficient is small and positive. In the old RBMK designs, it was very positive, and thus the increase in reactivity was too great for the response to mitigate the event (Control rods took 20 seconds to drop). However, the event occurred because they were running a dangerous test with an inexperienced staff, while the reactor had high poison concentrations. Control rods were removed beyond what should have been allowed. A scram after the test rapidly inserted the poorly designed control rods and between some breaking, jamming and the initial reactivity jump, the reactor increased in reactivity, the core melted and boiled off all the water. The steam created exploded the reactor top. The heat from the reactor and air through the broken room caused the graphite to ignite and burn.
