Water loss in operating an HDR faciUty may result from either increased storage within the body of the reservoir or diffusion into the rock body beyond the periphery of the reservoir (38). When a reservoir is created, the joints which are opened immediately fill with water. Micropores or microcracks may fill much more slowly, however. Figure 11 shows water consumption during an extended pressurization experiment at the HDR faciUty operated by the Los Alamos National Laboratory at Fenton Hill, New Mexico. As the microcracks within the reservoir become saturated, the water consumption at a set pressure declines. It does not go to zero because diffusion at the reservoir boundary can never be completely elirninated. Of course, if a reservoir joint should intersect a natural open fault, water losses may be high under any conditions. 

Bolton s opinion was bolstered in June 2005 by Senator Richard Lu-gar s survey of 85 non-proliferation and national security analysts from the United States and other nations. It was designed in part to characterize the risks related to the terrorist use of CBRN. The survey revealed that experts believe the probability of an attack somewhere in the world with a CBRN weapon was 50% over the next five years and 70% over the next ten. An attack with a radiological weapon was seen as the most probable with the likelihood of an attack with a nuclear or biological weapon considered about half as plausible [37]. The average probability of a nuclear attack in the next ten years was nearly 30%, with experts almost evenly divided between terrorist acquisitions of a working nuclear weapon versus self-construction [37]. The average risk estimate over ten years for major chemical and biological attacks was 20%. Senator Lu-gar concluded The bottom line is this for the foreseeable future, the United States and other nations will face an existential threat from the intersection of terrorism and weapons of mass destruction. ...

Gradnate edncation and research is generally not designed to prepare stndents to address real-world issnes in technology, especially national secnrity related concerns. Stndents fields of stndy tend to be narrow with limited exposnre to research and issnes in other scientific disciplines. The research that is envisioned as most beneficial to national secnrity is often interdisciplinary—an intersection of chemistry, biology, physics, engineering, and materials science. Gradrrate... 

This nebulous region, where science, politics, and agendas intersect, is exactly the territory occupied by the recent U.S. National Assessment of the Potential Consequences of Climate Variability and Change (hereafter the USNA).1 In this chapter, I examine the USNA, demonstrate that the models that serve as its basis are inconsistent with observations, and conclude that it... 

Similar anomalies over buried ore deposits have been reported by other Chinese workers (see Chapter 13). Using a gold-film detector, workers at the Chinese National Non-ferrous Metals Corporation (CNNC) analysed Hg in soil gas and near-surface atmosphere at the Naking Pb-Zn mine, where stratabound ores occur in fractures in Permo-Carboniferous strata. The region is covered by about 30m of allochthonous overburden. Mercury anomalies of up to three times background occur in both soil gas and near-surface atmosphere above a fault that intersects the ore (Fig. 12-23). These are coincident with higher-contrast Hg soil anomalies, but corresponding Pb and Zn data are not available.

It is important that safety professionals acquire a working knowledge of the ADA as well as key areas in which the ADA and safety function may intersect in order to be able to recognize when the ADA may be applicable to the situation. Safety professionals should be able to recognize when a potentially qualified individual is requesting an accommodation and appropriately address the situation in order to comply with the ADA. As noted by Mr. David Fram, director of ADA and EEO Services from the National Employment Law Institute, in his 2010 presentation, utilization of the simple question How can I help you as the initial response can open the doors to communications between the safety professional and employee, as well as starting down the right path to ensure compliance with the ADA. ...
