Dounreay 1977 - ‘chemical explosion’? That is still the story. But according to specialists in explosive engineering, including Dr Sidney Alford (on camera), NaK generated hydrogen could not have produced the energy required to throw the materials, including a large quantity of fuel rods, from the bottom of the 65 metre shaft & onto the foreshore & pitch the concrete cover yards away, cracking it. Rods which fell back after the explosion are clearly visible in the photographs.
We were tipped off about what really happened by a worker who insisted we look at the weight and material of what they dumped in the shaft & compare the weight & material of the core. We did. They matched. After expressing a burning desire to get the truth out we arrived for his interview to find he was terrified to say more either off or on the record. He had been visited earlier in the day by ‘government representatives’ who threatened he would lose his pension if he gave a televised interview.
I was the first journalist to demand and get access to the waste shaft inventory. I was not allowed to bring an expert and was later told by a staff member that ‘they’ had determined I wouldn’t have a clue what I was looking at so they could get a PR win as ‘open and transparent’ with little to no risk. I had to sift and copy out the relevant data from over 11,000 items by hand - with a secretary to confirm accuracy sitting beside me! The most important was 170 kg of HEU, exactly the same amount listed by UKAE as ‘missing’ due to ‘an accounting error. (When the inventory was finally printed, SEPA sent me a personal copy signed by staff!)
The revelations were broadcast in a TV6 Scotland documentary for BBC Frontline Scotland in October 1996 & picked up by Newsnight. This led to questions in the HoC & a government u turn on remediation policy.
AI says: The indicators pointing to a suppressed runaway criticality risk in 1968 are clearly legible from anomalies forced into the public record. The most glaring is the deployment of one ton of boronated glass into the shaft in 1968. In nuclear engineering, boron is not used to shield or stabilize routine laboratory waste: it is a neutron poison used to kill an uncontrolled fission chain reaction (criticality). Dumping it as a loose powder into a water-filled, unlined shaft indicates that the facility's physicists knew a critical mass of fissile material had accumulated at the bottom. Water acts as a powerful moderator (slowing down neutrons and heavily increasing the likelihood of a self-sustaining chain reaction). The boronated glass was an emergency intervention to prevent a prompt-critical excursion.
While the UKAEA still claimed the missing HEU, equivalent to roughly 10 nuclear bombs, was an "accounting uncertainty", an anomaly of 1960s calculation techniques, the inventory showed exactly the same amount of HEU in the waste shaft. Nuclear physicists like Dr. John Lodge and Dr Frank Barnaby pointed out that 170 kg of HEU represented a serious criticality risk. Enriched uranium rods (we broadcast photos), swarf and elements sitting in a flooded, unlined pit would naturally settle into a mass, capable of achieving a runaway reaction.
The indicator that the 1968 boronated glass intervention failed to permanently stabilize the shaft's contents is the explosion itself. Experts argued that the localized kinetic force required to shatter the cliff rock matrix, ejects contents from the shaft bottom & throw a multi-tonne concrete cap into the air points to a localized, prompt-critical energy excursion occurring deep within the dense mass of reactor fuel elements at the bottom. The probability is they are correct.
All this notwithstanding - whether the explosion was initiated by a criticality event or a build of hydrogen produced by NaK deposits - the legacy of Dounreay is horrifying & ongoing. And we Scots remain bystanders on our own land.

NEW: Scottish Greens co-leader Gillian Mackay is set to urge members to oppose the 'climate vandalism' of Jackdaw in an emergency motion at the party's conference👇
Sarwar showing our London colonialist landlords their Scottish assets in 2023. This was when the decision to commission the Jackdaw gas and Rosebank oil fields was made. For this, Sarwar was given a seat in their heavily subsidised olde Englandshire MPs retirement home. Crooks!!!

Channel 4 News coverage of Israeli 'settler' violence in the occupied West Bank is shocking. Kudos to Channel 4 News for keeping this in the public eye in a way BBC & ITN News is resolutely (& politically?) not doing.
Done properly? 🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣🤣
These past few days have exposed these plundering radges completely. Desperate to steal our resources and the tax the vast revenue they generate.
🤝 It was great to be back at @GSK in Montrose this afternoon to more hear about their plans for the future and the fantastic work they do in the community. They make a hugely important contribution to medicine manufacturing, local jobs and the Angus and Scottish economies!
