A -- ADVANCED SYSTEM SURVIVABILITY EVALUATION TOOL SOL DTRA01-00-R-0040 DUE 072100 POC Barbara Roberson (703) 325-6671 E-MAIL: barbara.roberson@dtra.mil, barbara.roberson@dtra.mil. Development of Department of Defense (DoD) Advanced System Survivability Evaluation Tool (ASSET). The Defense Threat Reduction Agency (DTRA) has a requirement to support the Services in nuclear hardening and survivability issues, analysis, technology, and assurance. As a part of this mission, it is intended to develop and implement ASSET to assist the Services in the evaluation of system response in a nuclear environment. ASSET will provide analysis tools consisting of community accepted codes covering electrical and mechanical responses in nuclear threat environments, along with requisite data, integrated into a web-enabled, object oriented architecture. A Phase I preliminary study has been performed using Re-entry Vehicle/Re-entry Body (RV/RB) modeling in a nuclear exo-atmospheric environment as the test case. A computer architecture that is flexible, standard-based, and open has been selected for ASSET with links to parallel and distributed High Power Computing machines. A candidate list of codes and models has been identified for inclusion in the first implementation of ASSET. The required data sources for modeling a RV and benchmarking the tool have been investigated. This Phase II effort will consist of designing and creating the ASSET architecture, integrating and modifying, as required, the selected codes and collecting, processing and incorporating the required data sources. The ASSET architecture shall allow for conducting nuclear response sensitivity analyses and shall provide a systematic means of identifying the driving uncertainties in component and/or subsystem data. Standard code activities such as testing, benchmarking and validating, assuring security requirements, and developing ASSET related user documentation will be performed. At the end of Phase II, ASSET will incorporate the candidate codes along with the required data and system design models (CAD, etc) to conduct, in concert with appropriate AGT, a robust nuclear hardening and survivability analysis using a baseline RV across all component functional areas and exo-atmospheric environments. After the end of Phase II there will be a final assessment of the tool's capabilities. If successful, it is expected that new component descriptions can be added to ASSET, along with required new material or response data, to evaluate changes to the benchmarked RV or other systems within the valid regime of the code set. A period of performance of approximately 4 years is contemplated, organized into options and decision points. Multiple awards are being contemplated. To be eligible for award contractors must have a top secret facility clearance and contractor personnel must have a top secret security clearance. Requests to obtain a copy of solicitation number DTRA01-00-R-0040 must be e-mailed to barbara.roberson@dtra.mil, and include the company name, point of contact, e-mail address, street address, telephone number, and telefax number. All correspondence issued in regard to this solicitation will be issued electronically; hard copies will not be provided unless absolutely necessary. The estimated date for release of the solicitation is on or about 19 June 2000. Posted 06/01/00 (W-SN460625). (0153)
