Abstract [en]

Light optical and electron microscopy have been used to study both laboratory-scale and full-scale hot isostatically pressed (HIPed) copper as employed for encapsulation of spent nuclear fuel elements. This work includes the development of computing models for predicting the optimal conditions for HIPing copper and other possible encapsulation materials such as lead and alumina. Mechanical testing of HIPed samples has also been carried out. The current method of using hydrogen to reduce oxides at powder surfaces prior to HIPing is questioned on the basis that metallography reveals definite signs of hydrogen embrittlement. An alternative method of reduction is to use CO/CO//2 mixtures instead of hydrogen, and it is suggested that this approach could be strongly advantageous in future
