WASHINGTON (AP) — The House on Thursday approved an election-year bill to revive the mothballed nuclear waste dump at Nevada's Yucca Mountain despite opposition from home-state lawmakers. Supporters say the bill would help solve a nuclear-waste storage problem that has festered for more than three decades. More than 80,000 metric tons of spent fuel from commercial nuclear power plants sit idle in 121 communities across 39 states. The bill would direct the Energy Department to continue a licensing process for Yucca Mountain while also moving forward with a separate plan for a temporary storage site in New Mexico or Texas. The House approved the bill, 340-72, sending the measure to the Senate, where Nevada's two senators have vowed to block it.
