 * Ukraine rebels ‘building dirty bomb’ with Russian scientists - Maxim Tucker, The Times, August 1 2015
 * ''Rebels in Ukraine are working to develop a radioactive dirty bomb with the help of Russian nuclear scientists, according to a Ukrainian security service dossier obtained by The Times.
 * ''The report draws on hacked emails between rebels and intercepted radio communications, as well as a field agent’s findings. It claims that Russian specialists have withdrawn radioactive industrial waste from a secure bunker at the Donetsk state chemical plant and moved it to a rebel military base, where it can be combined with explosives to create a devastatingly effective weapon.

 * According to Anatolii Sharii, makes as much sense as inviting engineers from Mercedes to make a bicycle from waste garbage. But there is a nuclear waste disposal site close to an ammunition and mining explosives factory in Donetsk regularly shelled by Ukraine by half-ton Tochka U munitions. DPR asked OSCE to inspect for environmental dangers due to shelling. In the end, attempts of Ukraine to render Donetsk not inhabitable is presented by Ukrainian press  as dirty bomb attempt  by rebels.

February, 8
A very powerful explosion (videos available) was reported in Donetsk on 8 February. Later it was said  that a chemical plant  in Donetsk  was hit by Tochka U  missile (fragments shown by Basurin). Preliminary information is that nobody was killed in that explosion. Investigators were on the scene next morning, but the area was further shelled by Ukraine; thus fragments were found and shown next morning. The plant traditionally produced explosives for mining and defense, and utilized old munitions, according to old Ukrainian sources. DPR sources say that the plant is currently producing paints and dry mixes.

 * ''Wonder why this same spot has been shelled so many times? Ballastic missiles, Tochka U and recently a thermobaric device? It is because this is where the Ukrainian government housed a depostitory of used nuclear waste.....SO...In effect Kiev is trying its hardest to detonate what is known as a DIRTY NUCLEAR BOMB.....

 * ''The radiation background level could have grown in Donetsk due to the powerful explosion in the State Factory of Chemical Products, because a nuclear waste depository is situated there, claimed executive director of the state enterprise East Ukrainian Ecological University Dmitriy Averin according to OstrovV website.
 * ''“It is not reliably known what exactly happened there (at the chemical works in Donetsk. – ed.). This is the third explosion occurring in its territory. It is there that one of the nuclear waste depositories of the Ministry of Defense of Ukraine is situated”, – the expert remarked, having added that there is a chance of destruction of this depository.
 * ''Averin also said that no one is monitoring the environment in the “occupied territories”, as he put it, that is why people might know nothing about the contamination.
 * ''Fortunately, he is mistaken, but he could have unintentionally revealed the purpose of Ukrainian Army repeated attempts to turn the area of the chemical plant in Donetsk into a replica of the Moon surface.

Chemical reaction
2NH4NO3 → 2N2 + O2 + 4H2O + 236 kJ (1.47 kJ/g; while TNT is 4.2 kJ/g)

2750 tons NH4NO3 is roughly 965 tons TNT (and only part of it was involved in the second bang).
