CARLSBAD, N.M. (AP) — U.S. nuclear regulators have hosted their final public hearing on a proposal to build a multibillion-dollar complex in southern New Mexico to store spent nuclear fuel from commercial power plants around the country. And there’s still disagreement about whether granting a license to Holtec International would be a good thing. The Nuclear Regulatory Commission heard from supporters and critics during Wednesday's meeting. The commission's draft environmental review says the project would have minimal environmental effects. A study on the project’s impact on human safety is pending. That will require another round of public comment.
