Judge's initial brief from government ministers was to "hold and fold" the UKAEA before shutting it down, at a potential loss of 2,800 jobs. Judge proposed an alternative plan, where the business would be built up, internationalised and then privatised. The agency's main business was decommissioning old British nuclear sites; Judge pushed for similar contracts on sites in the former Soviet Union and pursued partnerships in countries such as Korea. She also lobbied the Tony Blair government to end its opposition to nuclear power. These activities publicised the work of the agency amid an increase in positive sentiment towards nuclear power in the mid-'00s, with governments commissioning new reactors in order to meet carbon emission targets. She describes her time with UKAEA as "like spinning straw into gold", referring to her initial brief to close down the agency. In 2010, she was appointed Commander of the Order of the British Empire (CBE) for services to the Nuclear and Financial Services Industries.
