In February 2002, Vanguard began a two-year refit at HMNB Devonport. The refit was completed in June 2004 and in October 2005, Vanguard completed her return to service trials (Demonstration and Shakedown Operations) with the firing of an unarmed Trident missile. During this refit, Vanguard was boarded by a pair of anti-nuclear protesters who spent half an hour on board before being challenged. They were charged with damaging a fence which they cut to access the submarine.
In January 2012 radiation was detected in the PWR2 test reactor's coolant water, caused by a microscopic breach in fuel cladding. This discovery led to Vanguard being scheduled to be refuelled in its next "deep maintenance period", due to last 3.5 years from 2015, and contingency measures being applied to other Vanguard and Astute-class submarines, at a cost of £270 million. This was not revealed to the public until 2014.
