The phrase "accidental operation" is correct and usable in written English.
It can be used to describe an action or event that occurs unintentionally or by mistake, often in the context of machinery or processes.
Example: "The machine malfunctioned due to an accidental operation by the technician, leading to unexpected results."
Alternatives: "unintentional action" or "inadvertent operation."
Both HEU and LEU fuels behave similarly in the normal operation, while higher temperatures are obtained for the accidental operation in the case of the LEU fuel.
Design proposals for both connections are presented, together with the results of finite element mechanical analyses which demonstrate the feasibility to support the blanket and shield modules during normal and accidental operation conditions.
In contrast, the WL system is intended to fail in a predictable and irreversible manner under accident conditions and render the entire system inoperable before an accidental operation of the SL system.
Usability of this fuel in low-power research reactors was demonstrated for both normal daily and accidental operation conditions even if the power of the reactor touches 142 kW during the design basis accident simulation.
To investigate the thermo-mechanical behavior of the current WCCB blanket design version under normal operation and accidental operation scenarios (e.g. in-box loss of coolant accident (LOCA)), the finite element thermo-mechanical analyses of a full blanket module were performed by using ANSYS Multiphysics code.
The likelihood that the WL system will fail to deactivate the entire system before the SL system fails (i.e., degrades into a configuration that could allow an accidental operation of the entire system) is referred to as probability of loss of assured safety (PLOAS).
The fuel proved to be usable in both normal daily and accidental operations.
Although load scheduling and power allocation already work well during normal operation, accidental faults or hostile damage may trigger a situation requiring robust recovery to normal operation.
Structural analyses is carried out to assess the stress distribution in the fiber reinforced plastic insulator, the alumina insulator and the integrated HVB for different load cases like operational orientation (horizontal), normal operation and accidental case.
This paper discusses the details of the process design, and process flow diagrams of the both the helium cooling systems, their operational states with reference to the ITER machine operational states, and performance & behavior of the helium systems during normal operation and accidental conditions.
The deterministic analysis has achieved the following results: the Ignitor machine, both during routine operation and accidental sequences, presents a negligible environmental impact and radiological risk.
