By June 2004 Iraqi authorities had begun rebuilding facilities at the Tuwaitha research center once used by Saddam Hussein to pursue nuclear-weapons ambitions. The reconstruction under way at Tuwaitha, despite its potential for generating controversy, was no secret. The effort involved cleaning out, repairing, painting, and refurnishing office and laboratory buildings at the site. The intention is to create space to house research and development efforts by Iraq’s newly reconstituted Ministry of Science and Technology. Those research efforts will focus on agriculture, water, petrochemical and other projects. The cost of reconstruction was estimated at about 30-million dollars. The Coalition Provisional Authority is not financing the rebuilding.It is being paid for by the Development Fund for Iraq, established by the United Nations. The United States has been a major donor to the fund and it is managed by the Coalition Provisional Authority. While it is unclear whether Iraqi scientists will be able to conduct nuclear research at Tuwaitha again, there has been radioactive contamination at the site and radioactive materials once stored there are missing.
