[en] The goals and main results of FISRE-project (Fire Safety Research) from the years 1999-2002 are reported in the presentation. The project has been organized into three subprojects the titles of which cover: (1) effect of smoke and heat on electronics; (2) modelling of fire scenarios for SPA; and (3) active fire protection equipment. Critical heating times of metal case equipment have been measured and modelled. A universal design curve was proposed for risk analysis. Exposing real and mock-up circuitry to smoke acute effects of smoke and humidity were studied on insulation resistance of electronics used in programmable automation. Relevant physical parameters of smoke and electrical performance of circuitry were measured online. A quantitative calculation model for smoke exposure, deposition on surfaces, and required protective layer performance is proposed. A new practical method for measuring of emissivity of metal surfaces was proposed, and tested by experiments. A Monte Carlo calculation platform PFS is presented for the distribution of the probability of the next target loss time in a cable tunnel in a NPP. Preliminary results using realistic distributions of the input parameters are shown. Use of database is widened for general fire scenarios. A new time lag model for smoke detectors is proposed. Modelling of active fire protection devices was started. Data collection and reduction work for extracting reliability data of fire detection and sprinkler systems in both nuclear and non-nuclear installations was carried out and preliminary analyses performed. Finally, applications of new performance based fire safety engineering are demonstrated by describing some recently constructed buildings. (author)
