Accidents creditable

In the current Paks procedure dealing with primary break accident, credit is given to the closure of the main loop isolation valves. The following considerations apply ... 

Subsidies represent an often hidden financial benefit that is given to particular energy sources by government institutions in the form of tax credits, research and development (R rD) funding, limits on liability for certain kinds of accidents, military spending to protect Middle East oil supply lines, below-market leasing fees for use of public lands, and other... 

Abel takes the credit for explaining that the accidents with nitrocellulose occurred as the result of incomplete removal of readily decomposable products, i.e. they were due to inadequate purification ( stabilization ) of the guncotton.

The accident was thoroughly investigated including, to the Navy s credit, the systemic factors as well as the technical failures and deficiencies. Deep sea photography, recovered artifacts, and an evaluation of the Thresher design and operational... 

Most accident analyses stop at this point, particularly in that era. To their credit, however, the investigation continued and looked at why the technical deficiencies existed, that is, the management and systemic factors involved in the loss. They found deficient specifications, deficient shipbuilding practices, deficient maintenance practices, inadequate documentation of construction and maintenance actions, and deficient operational procedures. With respect to documentation, there appeared to be incomplete or no records of the work that had been done on the submarine and the critical materials and processes used. 

To its credit, the accident investigation board went beyond the usual chain-of-events model and instead interpreted the acddent in terms of a complex and flawed process ... 

The partition of iodine between liquid and gas phases is enhanced by the alkalinity of the solution. The spray system should be designed so that the spray solution is within material compatibility constraints. Iodine scrubbing credit is given for spray solutions whose chemistry, including any additives, has been demonstrated to be effective for iodine absorption and retention under post-accident conditions. 

Clearly enough, credit factors depend on the considered accident frequencies and release probabilities. In current analysis typical values considered in the bulk transport of chemicals were used (Cozzani et al. 2004). Table 4 reports the UPI a UHI for the bulk transport options. 

Hydrogen powered cars are assessed similarly to transport units. In fact for a mobile unit, credit factors of releases caused by crash accidents can be considered at least an order of magnitude more probable than operative failures. Overall indices for a single vehicle are reported in Table 4. The analysis of both the potential index (PI) and the hazard index (HI) immediately reveals that the innovative technology of metal hydrides yields safer storages by the application of the moderation principle of inherent safety (CCPS, 1996). 

LOPA is a simplified risk assessment to determine if there are sufficient IPLs against an accident scenario. As illustrated in Fig. 1, many types of protection layers can be considered against an unwanted accident. The thickness of the arrows represented in Fig. 1 indicates the frequency of the specified consequence for the initiating event. The results of LOPA can be used for the decision-making for numerical criteria and the number of IPL credits althou LOPA does not suggest which IPLs to add or which design to choose [William G. Bridges. 2001]. 

Time-loss analysis is a special-purpose technique used to evaluate accident responses. System Safety Development Center courses that teach the technique credit the National Transportation Safety Board (specifically Driver and Benner) with developing and reporting the technique. 

In addition, make sure all dates of employment, traffic violations, and accident data (if any) match state motor vehicle records (MVRs) and pre-employment screening reports (from any credit-reporting agency used by the organization). 

The origin of the Domino Theory is credited to Herbert W. Heinrich, circa 1931, who worked for Travelers Insurance. Mr. Heinrich nndertook an analysis of 75,000 accident reports by companies insnred with Travelers. This resulted in the research report titled The Origins of Accidents, which concluded that 88 percent of all accidents are caused by the unsafe acts of persons, 10 percent by unsafe physical conditions, and 2 percent are Acts of God. His analysis of 50,000 accidents showed that, in the average case, an accident resulting in the occurrence of a lost-time work injury was preceded by 329 similar accidents caused by the same unsafe act or mechanical exposure, 300 of which produced no injury and 29 resulted in minor injuries. This is sometimes referred to as Heinrich s Law. Mr. Heinrich then defined the five factors in the accident sequence, which he identified as the Domino Theory. Heinrich s work is the basis for the theory of behavior-based safety, which holds that as many as 95 percent of all workplace incidents are caused by unsafe acts. See also Accident Chain Behavior-Based Safety. 

The assessment of severe accidents should account for the full design capabilities of the plant, including the use of some safety and non-safety systems beyond their originally intended function to return the potential severe accident to a controlled state and/or to mitigate its consequences. If credit is taken for extraordinary use of systems, there should be a reasonable basis to assume they can and will be used as analysed. 

The aluminum cladding of the fiiel assemblies are credited to some degree in the analyses of all postulated accidents for providing confinement of radionuclides and fissile material contained in the fuel assemblies in a manner which minimizes their release to the K-, L-, and P-Reactor Disassembly Basins. Should the aluminum cladding be breached fissile material may precipitate onto the basin fioors or be carried into the filtration systems potentially forming a critical masses. Also, the basin water radioactivity level may rise to unacceptable levels and pose increased consequence to the workers, public, and environment should the water leak to the environment or an uncontrolled area.
