Following the Zernovkan 1st Special Forces Regiments clearing of a small portion of Akzova, army engineers have begun construction on a contrete structure, nicknamed the sarcophagus, that will cover the main reactor building of the Akzova Nuclear Power Plant. Workers will only be able to be around the plant for 30 minutes at a time, due to the risk of Acute Radiation Syndrome (ARS), workers are not allowed to remain at the plant for a span of time longer than the 30 minute limit.
