Nuclear talks of Iran with the six world powers known as P5+1, involving Russia, China, France, Britain, U.S. and Germany, are set Tuesday (Oct. 15) in Geneva, Switzerland, according to Press TV Iran.

Sources, associated to the Iranian-negotiating team, said Tehran is targeting a win-win situation that will alleviate "the logical concerns" of all the countries involved as it hopes for "tangible results."

In an interview with Hamidreza Emadi, director of Press TV's newsroom, Sunday, the report said Tehran will uphold 10 principles and will put a firm foot forward in abiding by these principles for the nuclear talks Tuesday.

The principles include a strong objection against enrichment and shipment of uranium beyond Tehran's soil. If P5+1 insist on uranium enrichment and shipment beyond the Iranian soil, it will be the end game for the nuclear talks and no more negotiations will be entertained in the future.

Iranian diplomats were quoted saying that "recognition of the right to enrichment on Iranian soil is an end game" and not a prerequisite as in the past.

However, Tehran expressed its openness for negotiations over its nuclear energy program declaring that the nuclear talk should be "serious" and "purposeful." It said it expects the same attitude from Russia, China, France, Britain, U.S. and Germany.

The nuclear talk Tuesday is going to be the very first negotiation since President Hassan Rouhani took office in August. Rouhani vowed to be open for constructive talks discussing the dispute over Iran's nuclear power system.

The U.S., Israel and the European Union had repeatedly accused Iran for utilizing its nuclear energy program for non-civilian objectives. Hence, they call for Tehran to be under sanctions which Tehran deemed as illegal.

Iran had always denied the accusation arguing time and again that it upholds the Non-Proliferation Treaty and its membership of the International Atomic Energy Agency. Being a signatory and member for both organizations, Iran defends that the only right they practice is the right to use nuclear technology for peaceful purposes such as energy and medical use.

Meanwhile, U.S. Secretary of State John Kerry expressed optimism that the nuclear talk opens diplomacy over Iran's nuclear program and Israel's security needs.

In a press conference via satellite from the American Israel Public Affairs Committee summit in California, Kerry said, "I want you to know that our eyes are open, too. While we seek a peaceful resolution to Iran's nuclear program, words must be matched with actions. In any engagement with Iran, we are mindful of Israel's security needs."
