Semiscale Test S-02-8 mini-topical for standard problem five

Test S-02-8 of the Semiscale Mod-1 blowdown heat transfer test series (Group 2) was conducted to supply data for the U.S. Nuclear Regulatory Commission (NRC) Standard Problem Five. To assure the credibility of the data and thus ensure the validity of Standard Problem Five, an analysis of the results of Test S-02-8 was performed and is presented. This analysis consisted of investigations of system hydraulic and core thermal data. The credibility of the system hydraulic data was investigated through comparisons of the data with data and calculations from related sources (Test S-02-7 and RELAP4) and, when necessary, through explanation of physical events. The credibility of the core thermal data was based on a thorough analysis of physical events. The results of these investigations substantiate the validity of Test S-02-8 data
