Nuclear plant safety security

To assure the safety and physical security of nuclear materials, the security of data, and the organization of security, restricted-pass access, and the intrafacility regime, the plant has an operating Safety and Documentation Group, which is an independent structural unit.

Various network attacks by external agencies are quite common and have been covered at length in the previous chapter. Nuclear plants are always the major targets. So, nuclear power plant I C systems are generally kept isolated from external communication systems. Also the network deployed for safety and safety-related systems must be very well secured utilizing various techniques discussed in the previous chapter, such as zone conduit methods. Possible major attacks could be from ...

Armenia is particularly sensitive to its energy security because it faced a crippling energy crisis between 1992 and 1995 as a result of the collapse of former markets in the Soviet Union. The severity of the crisis was compounded by a decision in March of 1989 to shut down the Armenian nuclear power plant due to pressure from environmental groups and safety concerns following the 1988 earthquake. Instability in the power grid resulted in over utilization of hydro resources, particularly Lake Sevan. 

Safety has always been discussed in various fields. The opposite of safety is danger. In general, the security for an industrial equipment/process/plant, even in the case of those rated as perfectly safe, is rarely felt to be perfect by the common man. A good example of such a situation is nuclear power stations. Although nuclear power stations are considered to be technologically perfect in almost all aspects, the installation of a new plant is not easily accepted by the residents in and around the site. This is because the residents do not feel perfectly secure instead, they are anxious about the occurrence of a serious accident, even though the chances of such an occurrence are rather small. 

In many countries, concerns about safety, short-term economics and supply of uranium are likely to be outweighed by the desire to acquire a relatively non-polluting and secure source of power. China, for example, plans to build 30 new plants by 2050, generating as much as 300 gigawatts10 of power. In certain European countries, such as France and Finland, nuclear energy is a lot more popular than it is in the U.S. 

These demanding goals are likely to be achievable only with systems of relatively low power compared to the lOOOMWe plants commonly used today, with the added benefit of greater security, safety, and public acceptance of the expanded use of nuclear power within developing countries. 

A review of the physical protection of nuclear power plants is typically not included in the PSR because of the sensitivity of this subject and the confidentiality aspect. The security arrangements should prevent unauthorized actions that could jeopardize safety and their effectiveness should be periodically reviewed. 

In either process (10 CFR 50 or 10 CFR 52), before a nuclear power plant can be built and operated, approval must be obtained from the NRC. In both licensing processes, the NRC oversees the construction and operation of a facility throughout its lifetime to ensure regulatory compliance with the NRC s mission of protecting public health and safety, the environment, and the common defense and security. 

The Price-Anderson Act of 1957 (Public Law 85-256) limited the liability of the nuclear industry in the event of a nuclear accident in the United States. Because of the safety uncertainty posed by the nuclear industry in the United States, private insurance companies were unwilling to fully underwrite a nuclear power plant. The lack of financial security would have hindered the development of the nuclear industry. The federal government intervened with this amendment to the AEA of 1954.

Detailed discussions at component level starting from sensors, safety field bus, safe logic solvers, and final control elements are a unique addition to the book. The book also covers the security aspects of various networks, viz. firewalls and zone-conduit to name a few, which is also another unique feature of the book. The book also covers application of SIS in various plants covering fossil fuel power stations, nuclear power stations, oil and gas sector such as upstream, midstream, refinery, and petrochemicals. There have been supplementary data and information on statistical approaches, embedded controls, and cost impact and life cycle cost analysis to take care of advancement in technology and systematic approach toward the problem.
