USA’s Hanford nuclear site could suffer the same fate as Russia’s Mayak – or worse

Comment from Dtlt 21 Dec 19, TRUMP IS CUTTING THE BUDGET TO MONITOR AND TRY TO CLEAN THE HANFORD MESS IN HALF
Massive Nuclear Explosion similar to Kyrshtym by Mayak Can Happen at Hanford if the site is not Monitored and tanks not taken care of.

A Ten Thousand Gallon Tank at Mayak Exploded from Heat Decay. The Heat Deacy was from Strontium 90, Cesium 137, Cobalt 60 and Plutonium Stored in the Underground Tank. The explosion was equivalent to 100 tons of TNT. There are 55 million gallons of the same Radionuclide Mix stored at Hanford, in UnderGround Tanks. They used nitic acid to extract radionuclides at hanford as they did at Kyahym, by Mayak. The nitrates mixed with heat decaying rand hydrogen gas generating radionuclides are very much like the explosive brew that went off in Kyshtym in 1957 and there are 55 million gallons of the explosive brew at Hanford. The heat decay, heat emitting Radionuclides and Hydrogen gas generating explosive mix and the nitrates in the brew are very much at risk for a massive catastrophic chemical-radionuclide explosion . The Kyshtym disaster was a radioactive contamination accident that occurred on 29 September 1957 at Mayak, a plutonium production site in Russia for nuclear weapons and nuclear fuel reprocessing plant of the Soviet Union.

If the exlplosive stew becomes too concentrated and hot, the same thing will Happen there, contaminating a Great Portion of the Pacific NW USA and southe western Canada.

In 1957 the cooling system in one of the tanks containing about 70–80 tons of liquid radioactive waste failed and was not repaired. The temperature in it started to rise, resulting in evaporation and a chemical explosion of the dried waste, consisting mainly of ammonium nitrate and acetates (see ammonium nitrate/fuel oil bomb). The explosion, on 29 September 1957, estimated to have a force of about 70–100 tons of TNT,[10] threw the 160-ton concrete lid into the air.[8] There were no immediate casualties as a result of the explosion, but it released an estimated 20 MCi (800 PBq) of radioactivity. Most of this contamination settled out near the site of the accident and contributed to the pollution of the Techa River, but a plume containing 2 MCi (80 PBq) of radionuclides spread out over hundreds of kilometers. Previously contaminated areas within the affected area include the Techa river, which had previously received 2.75 MCi (100 PBq) of deliberately dumped waste, and Lake Karachay, which had received 120 MCi (4,000 PBq).
In the next 10 to 11 hours, the radioactive cloud moved towards the north-east, reaching 300–350 km (190–220 mi) from the accident. The fallout of the cloud resulted in a long-term contamination of an area of more than 800 to 20,000 km2 (310 to 7,720 sq mi), depending on what contamination level is considered significant, primarily with caesium-137 and strontium-90. This area is usually referred to as the East-Ural Radioactive Trace EURT
