Irradiating PtCl2 in a reactor core poses risks, particularly if aluminum (Al) is used as a container, as it can corrode when in contact with water at high temperatures, such as 300°C. The neutron flux could activate the Al, potentially leading to chemical reactions between chlorine and aluminum. If the aluminum cladding breaches, it could result in hazardous chemical reactions. To mitigate these risks, it is advisable to use a hermetically sealed stainless steel capsule for containment. Proper reactor type selection and operational conditions are crucial for safety.
