[0050] A fuel transfer simulator according to at least one example embodiment provides the advantage of facilitating the training process for personnel or groups of personnel performing fuel transfer operations. For example, it is important that new personnel be able to undergo training and team development on the complex processes associated with working in a multi-process facility so that they have sufficient experience to safely perform such processes. For example, SROs often first meet their fuel transfer teams when they assemble on-site during an outage. Ideally, they will have the opportunity to conduct team development at an off-site facility prior to an outage. A fuel transfer simulator system according to at least one example embodiment provides the advantage of a portable platform for conducting such training and team development.

[0051] An example refueling operation training solution includes using a full-size replica of the relevant portion of a BWR plant for training. Personnel can use the full-size replica to train by performing refueling operations as if they were in the actual BWR plant. However, such replicas are expensive and very large. Thus, it may be impractical to build such replicas in more than a limited amount at a limited number of locations. Thus, personnel wishing to train to perform refueling operations may need to travel to one of a limited number of geographic locations to use the full-size replica for training.

[0052] However, the fuel transfer simulator system according to at least one example embodiment provides the advantages of (i) being usable by personnel of all experience levels without risking damage to training facilities and mock-ups, and (ii) being portable so that the refueling operation training solution can be brought to a location convenient to personnel seeking training, instead of requiring personnel to travel significant distances for training.

[0053] A fuel transfer simulator system according to at least one example embodiment provides the advantage of supporting a safe and relatively compact method for allowing multiple users to practice BWR facility fuel transfer operations together.

[0054] The fuel movement simulator system, according to at least one example embodiment, provides the benefit of reducing overall fuel movement time by acclimating fuel movers (e.g., personnel moving fuel) to the process prior to beginning work within the reactor. Thus, the average fuel movement time may be reduced by reducing the time required for a reactor service technician (RST), with or without a senior reactor operator (SRO), to acclimate to the fuel movement process.

[0055] While a number of example embodiments have been disclosed herein, it should be understood that other variations are possible, and such variations should not be considered a departure from the spirit and scope of the present disclosure, and all such modifications obvious to those skilled in the art are intended to be included within the scope of the following claims.
