DUBAI - Iran said on Tuesday it had delivered two batches of domestically made nuclear fuel to a research reactor in an apparent attempt to trumpet nuclear advances before negotiations with six world powers on Wednesday.

If confirmed, Iran's ability to run the reactor with its own fuel would remove the basis for a mooted deal under which Iran would send enriched uranium abroad in exchange for such fuel, reducing its stockpile of potential atom bomb material.

"In their latest efforts, experts from Iran's Atomic Energy Organization succeeded in delivering two domestically-made nuclear fuel plates to the Tehran research reactor," state television reported on its website. "One of the two plates was loaded to the reactor," the report added.
