Title: BAGPIPE Containment Data and Phenomenology Report

Technical Report ·
DOI:https://doi.org/10.2172/802590· OSTI ID:802590

The BAGPIPE sub-critical experiment was executed on September 26, 1998, at about 13:07 hours. A steel and fibercrete containment barrier had been built at the entrance to the U1a.101b drift at the Nevada Test Site to form the BAGPIPE zero-room. The invert of the zero-room was covered with concrete and the ribs and back were covered with about 15 cm of fibercrete. The face was left uncovered to facilitate gas bleed-off into the alluvial formation. The volume of the room was approximately 3894 ft{sup 3}. Four small experimental packages were detonated. The LLNL containment goal for the BAGPIPE experiment was to confine all special nuclear material (SNM) to the zero-room and the alluvium surrounding the zero-room. The experiment and containment objectives are discussed more fully in the BAGPIPE Containment Prospectus and the associated addendum. Alpha-particle radiation detectors outside the BAGPIPE zero-room remained at pre-shot background levels after the experiment. A large number of swipes were taken around the BAGPIPE primary containment barrier and in the diagnostics room. No evidence that any SNM was released into the tunnel complex was found and the BAGPIPE containment was considered successful.
