BRUSSELS, July 20 (Reuters) - Cash-strapped European Union governments will not have to provide fresh money in order to fill a 1.4 billion euro ($1.81 billion) funding gap in a project to commercialise nuclear fusion -- the process that powers the sun.
Increased complexity and rising construction costs have seen the price tag for the International Thermonuclear Experimental Reactor (ITER) project rise to 16 billion euros ($20.76 billion), while the EU's share has more than doubled.
