still being washed ashore at Sandside Bay beach and one particle at a popular tourist beach at Dunnet in 2006. In 2012, a two million becquerel particle was found at Sandside beach, twice as radioactive as any particle previously found. of radiologically contaminated land, and of chemically contaminated land. of high and medium active liquors and of unconditioned intermediate level nuclear waste in store. of sodium, of which are radioactively contaminated from the Prototype Fast Reactor. Historically, much of Dounreay's nuclear waste management was poor. On 18 September 2006, Norman Harrison, acting chief operating officer, predicted that more problems will be encountered from old practices at the site as the decommissioning effort continues. Some parts of the plant are being entered for the first time in 50years. In 2007, UKAEA pleaded guilty to four charges under the Radioactive Substances Act 1960 relating to activities between 1963 and 1984, one of disposing of radioactive waste at a landfill site at the plant between 1963 and 1975, and three of illegally dumping radioactive waste and releasing nuclear fuel particles into the sea, resulting in a fine of £140,000. In 2007 a new decommissioning plan was agreed, with a schedule of 25years and a cost of £2.9billion, a year later revised to 17years at a cost of £2.6billion. Due to the uranium and plutonium held at the site, it is considered a security risk and there is a high police presence. In 2013, the detail design of the major project to decommission the intermediate level waste shaft was completed, and work was to begin later in the year. The work would include the recovery and packaging of over 1,500tonnes of radioactive waste. , the "interim end state" planned date had been brought forward to 2022–2025. In March 2014, firefighters extinguished a small fire in an area used to store low-level nuclear waste. On 7 October 2014, a fire on the PFR site led to a "release of radioactivity via an unauthorised route". The Office for Nuclear Regulation (ONR) concluded that "procedural non-compliances and behavioural practices" led to the fire, and served an improvement notice on Dounreay Site Restoration Limited. In 2015 decommissioning staff expressed a lack of confidence in management at the plant and fear for their safety. In 2016, the task of dismantling the PFR core commenced. Plans were also announced to move about of waste Highly Enriched Uranium to the United
