70 -- AYDIN DISPLAY GENERATOR UPGRADE SOL RS-AED-95-351 POC Mary Jo Mattia, Contracting Officer, 301/415-7315/, Penelope Kinney, Contract Specialist, 301/415-6576 The U.S. Nuclear Regulatory Commission (NRC) intends to enter into a sole source contract with Aydin Controls, Inc. to acquire replacement display generation systems for the Babcock & Wilcox (B&W) and General Electric BWR/4 full scope nuclear plant simulators. An option will be included for a replacement display generation system for the General Electric BWR/6 simulator. The upgraded system must be compatible with existing simulator graphical display software. An Aydin 7402 workstation with specifically matched components running a modified version of the Unix operating system is required for both simulators. The existing simulator graphical display software was specifically written to interface with Aydin display generators and is proprietary as are modifications which have been made to the operating system which controls the workstation. This workstation is compatible with Aydin's display generation software currently being used by the NRC Technical Training Center (TTC) in Chattanooga, Tennessee. The simulators are used by the TTC for full scope nuclear simulator training. Aydin Controls, Inc. is the only company that can deliver a product compatible with existing software because the Aydin display generator is proprietary. The period of performance is 24 months. This is not a request for proposal, since no solicitation will be issued. See Numbered Note 22. (0165)
