title: BIOS-4 as an embodiment of CELSS development conception.
abstract: Any attempt to create LSS for practical applications must take into account the possibility of castastrophic consequences if the problem of LSS reliability and stability is not solved.  An integrated conception of CELSS studies development as a possible way to increase its reliability is considered.  The BIOS-4 facility project is developed in the context of the conception.  Three principles of highly effective experimental CELSS facility design are proposed.  Some details of BIOS-4 design and its exploitation features are presented.
