The initial release of Shift in the Virtual Environment for Reactor Applications (VERA) provided users with the ability to perform ex-core calculations. After this release, a task was undertaken to optimize input parameters and output of desired quantities for ex-core calculations. As requested by analysts, this report presents the detailed input and output changes made to VERA to enhance usability. Specifically, some of the major optimizations added were detector and bioshield setup using the VERA common input, updated Shift input defaults, consolidated output, and output of pin importance's. Close interaction between developers, analysts, and users enabled these useful optimization updates, which will be included in the release of VERA 4.1, and some are included in VERA 4.0.1. Under these auspices, this work will continue under the VERA Users Group (VUG).
