A safe containing radioactive material at the Dabaa nuclear power plant was seized while another safe containing radioactive material was broken open and part of its contents taken, the newspaper said.
The government has alerted security authorities and asked that specialised teams help in the search for the stolen material, al-Ahram reported.
More than a dozen people were wounded last week when military police tried to disperse hundreds of Egyptian protesters demanding the relocation of the Dabaa plant, which is still under construction.
Plant staff have refused to go to the site because of the deterioration in the security situation there, al-Ahram said.
About 500 Egyptians rallied in front of the plant last week to demand that the project be terminated, with some saying they had lost their land on the plant`s site.
Soldiers and the protesters hurled stones at each other and exchanged gunfire after the protesters demolished a wall surrounding the site, a security source and witnesses said.
