Chicago Pile-1 Chicago Pile-1 Chicago Pile-1 (CP-1) was the world's first nuclear reactor. On 2 December 1942, the first human-made self-sustaining nuclear chain reaction was initiated in CP-1, during an experiment led by Enrico Fermi. The reactor's development was part of the Manhattan Project, the Allied effort to create atomic bombs during World War II. It was built by the Metallurgical Laboratory at the University of Chicago, under the west viewing stands of the original Stagg Field. Fermi described the apparatus as "a crude pile of black bricks and wooden timbers". The reactor was assembled in November 1942, by a team that
Enrico Fermi Nuclear Generating Station take six years. The cost is estimated at as much as $10 billion. CEO Anthony Earley said that DTE's analysis "so far shows that nuclear power will, over the long term, be the most cost-effective baseload option for our customers, ... We expect nuclear to remain the low-cost option, but we will continue to evaluate nuclear against other resources and will commit to proceeding with construction only at the right time and at the right cost". In March 2009, a coalition of citizen groups asked federal regulators to reject plans for Fermi 3, contending that it would pose a range
