Description
To clarify the reasons of softening of standard NRM fuel pins in the course of nitriding in nitrogen or oxy-nitriding in hydrogen flow which includes oxygen and nitrogen impurities there was performed anneals of carbide and graphite fuel pins with high content of uranium (∼38 % (mass)) in weak nitrogen flow under the pressure of ∼19 MPa. It was shown that softening influence of fuel pins nitriding caused by increase of porosity in generative carbonitride material and by occurring of cracks and stresses in this material. (author)
