Late Time Containment.
Abstract
Major contributions in the Late Time Containment research effort are summarized. Test design activity showed that cavity venting into a tunnel could effectively lower cavity pressure on a fast time scale and that a reasonable, fast-turn-around horizontal line of sight system could be developed for satellite testing. Analysis of past experience has led to a containment summary report for Mighty Epic and much of the data for a Diablo Hawk report. A study of cavity pressure measurements confirms that complex processes are involved probably including some form of cavity gas leakage at late time. LOS flow modeling and calculations based on new techniques are in reasonable agreement with the limited data available. Flow calculations of PI test configurations probably indicate that the neglect of the pipe wall in the calculations was detrimental. An analysis of grout sphere experiments by SRII shows that strong evidence for rapid stress relaxation exists in the data. Finally, several miscellaneous activities are detailed. (Author)
