A video, allegedly showing North Koreans working inside the facility, will be shown to members of the Congress.
The officials said the pictures of the site, code-named Al Kibar by the Syrians, played a crucial role in Israel's decision to bomb the facility.
According to sources quoted in the US press, the video will also show that the design of the Syrian reactor core is the same as the North Korean reactor at Yongbyong.
Syria's ambassador to the United Nations has denied that his country had assistance from North Korea.
"We said it many times in the past. There (was) no Syrian-North Korean cooperation whatsoever in Syria...we deny those rumours" Syrian Ambassador Bashar Jaafari said.
There was a news blackout for weeks after the Israeli attack in September.
When news came to light of the possible nuclear reactor, the US and Israel refused to comment, with officials saying they feared that the Syrians would retaliate against Israel.
