Abstract : It is proposed to fill the empty channels surrounding the active core of the X pile with thorium carbonate. Three rings of the carbonate would be put around the pile. The inner ring would be not less than 30 cm. from the nearest uranium. The thorium would serve two purposes: the escaping neutrons would produce U233 in it and it would protect the concrete by decreasing the neutron flux. The estimated yield of U233 is .012 gm/1000 kw day and the thorium would absorb about 50% of the escaping neutrons.
