WASHINGTON -- Yucca Mountain amendments are complicating Senate debate on a nuclear cooperation agreement between the United States and India.

A bill carrying out the agreement would allow U.S. companies to sell nuclear reactors and nuclear fuel to India for the first time in decades while requiring the South Asian nation to work with the United States on nonproliferation matters.

Sen. Harry Reid, D-Nev., supports the bill but is trying to add an amendment requiring an affirmative vote from Congress in the event that spent fuel from India might be shipped or stored in the United States.

The government has designated Yucca Mountain in Nevada as a repository site for U.S. nuclear waste. Bush administration officials have said the Nevada site may someday play a role in the Global Nuclear Energy Partnership, an international fuel reprocessing initiative.

Reid's amendment irked Sen. Larry Craig, R-Idaho, when it surfaced last week, Senate aides said.

Craig proposed a counter-amendment directing the Energy Secretary to start shipping nuclear waste to Yucca Mountain "as soon as practicable."

Both amendments were on a schedule for debate proposed Tuesday by Majority Leader Bill Frist, R-Tenn. Amendments from Sens. Russ Feingold, D-Wisc., Byron Dorgan, D-N.D., and Barbara Boxer, D-Calif., also were announced.

But the India bill was put on the back burner when Frist and Reid, the Senate minority leader, could not agree on a schedule for the bill. Reid said the bill probably will be considered after the election.

Reid said his amendment is the same as one that was put on the India bill in the House by Rep. Shelley Berkley, D-Nev. The provision was accepted by the Bush administration, according to Richard Urey, Berkley chief of staff.

A second Reid amendment would require an annual report to Congress on how India manages its nuclear waste.

According to the Nuclear Energy Institute, India has generated 5,000 metric tons of used nuclear fuel in its reactors.
