This report documents the second phase of the Remote Operated Vehicle with CO{sub 2} Blasting (ROVCO{sub 2}) Program. The ROVCO{sub 2} Program`s goal is to develop and demonstrate a tool to improve the productivity of concrete floor decontamination. The second phase integrated non-developmental subsystems on to the ROVCO{sub 2} system and performed quantitative decontamination effectiveness, productivity, and reliability testings. The report documents these development activities and the analysis of cost and performance. The results show that the ROVCO{sub 2} system is an efficient decontamination tool.
