This calculation note analyzes headspace concentrations of hydrogen dependent upon assumed ventilation flow rates provided for tanks 241-C-106 and 241-AY-102. The analyses are based on measured or estimated steady state hydrogen release rates. Tank 241-C-106 is analyzed prior to sluicing; tank 241-AY-102 is analyzed both prior to and after completion of sluicing. Specific analyses, using both best estimated and bounding hydrogen generation rates, include the minimum primary ventilation flow rates required in the tanks to ensure that the steady state hydrogen concentration in the respective tank headspace does not exceed 25% and 100% of the LFL. The headspace hydrogen concentration as a function of time as well as the time required to reach 25% and 100% of LFL upon complete loss of active ventilation, starting from the steady state hydrogen concentration based on a 200 CFM minimum flow rate in tank 241-C-106 and a 100 CFM minimum flow rate in tank241-AY-102. The headspace hydrogen concentration as a function of thee following partial loss of active ventilation (i.e., step changes to l60, l20, 80, and 40 CFM ventilation flow rates) in tank 241-C-106, staffing from a 200 CFM flow rate and the corresponding steady state hydrogen concentration based on the 200 …

I was asked to speak on the subject of ``What do we mean by sustainability and what factors have the most impact on it?`` I am afraid I must admit that if there is a generally accepted definition of sustainability, at least as applied to mankind and terrestrial systems, then I am not aware of it. But I expect you know that, or you would not be having this session. The subject of sustainability is one that interests us all. In fact, I think that it fascinates us all because the concept is one to which we can intimately relate. Sustainability implies eternal life; and throughout history, humankind has sought, sometimes secretly, sometimes openly, eternal life, if not for ourselves at least for our progeny. What I will try to do is (1) briefly discuss some of what has been said about this topic, (2) propose a definition that I believe is workable, and point out some of the issues that derive from it, and then (3) suggest what I think we can all do to ensure the sustainability of the planet. I confess to you at the outset that I am an optimist on this subject, and a technological …
