Part 4/10:
Samples taken from these crusts and their surrounding areas revealed dominant presence of calcium and titanium, with peaks reaching up to 8% and 6.5%, respectively. The high calcium content is notable, possibly originating from calcium-rich deposits or reactions involving calcium-bearing materials within the reactor environment.
Other elements detected include phosphorus, silicon, copper, nitrogen, and small quantities of iron. The coexistence of phosphorus and calcium suggests the formation of phosphates, which are common high-temperature corrosion products or reaction byproducts. The detection of titanium indicates its role either as a structural component or as part of reaction crusts formed under operational conditions.
