FACTBOX: Efforts to dismantle N.Korean nuclear program

(Reuters) - North Korea agreed in weekend talks with the United States to fully account for and disable its nuclear programs by the end of this year, negotiators said.

The announcement is the latest step in the implementation of a "six-party" deal agreed on February 13.

North Korea, which tested a nuclear bomb last year, promised the United States, South Korea, Russia, China and Japan that it would give up its nuclear facilities and technology in exchange for a range of economic and diplomatic benefits.

Following are details of the deal, and progress on implementation:

FEBRUARY AGREEMENT

First phase:

-- North Korea to shut down and seal its Yongbyon nuclear complex, including 5 Megawatt reactor and plutonium reprocessing plant, within 60 days.

-- International Atomic Energy Agency (IAEA) inspectors to be allowed back to Yongbyon within the 60 days to ensure North Korea's ability to produce weapons-grade plutonium is disabled.

-- South Korea, China, the United States and Russia -- but not Japan -- to provide 50,000 tons of heavy fuel oil or an equivalent value of economic or humanitarian aid in return.

-- The steps do not involve the provision of 2,000 Megawatts of electricity generating capacity that South Korea pledged in a September 2005 deal reached by the six countries, before North Korea conducted its surprise nuclear test. This part of the deal is reserved for after North Korea has completely denuclearized.

Path to full denuclearization:

-- North Korea to complete measures to "disable" its nuclear programs in exchange for 950,000 tons of fuel oil, or the equivalent value in aid, from the four countries.

-- The measures include providing a complete list of all nuclear programs, including inventory of a plutonium stockpile. Washington believes North Korea may have enough nuclear fuel to make more than eight or nine atomic weapons, and also a hitherto undeclared uranium-based nuclear program.

-- All nuclear facilities, including reactors and reprocessing facilities, to be put beyond use.

Improving ties:

-- Under separate bilateral forum, United States begins process to remove North Korea from list of state sponsors of terrorism and lift trade sanctions.
