  • Best practices in the utilization and dissemination of operating experience at nuclear power plants

    Background Few events occur today that reveal a completely new cause or failure mechanism. Although not clear during an event, most investigations find that internal or external industry operating experience (OE) was available which, if used effectively, could have prevented the event. In fact, a station manager provided the following comments concerning a recent event at his station: “This event ...

  • Best practices in identifying, reporting and screening operating experience at nuclear power plants

    Background Operating experience is a valuable source of information for learning and in the process improving the safety and reliability of nuclear power plants. One of the main elements of this process is the collection of event information in a systematic way that conforms with agreed reporting thresholds. The reported information than needs to be screened to ensure that all significant matters ...

  • Experiences in the construction and operation of a nuclear desalination demonstration plant: Part II

    A hybrid desalination plant consisting of 1800 m³/day Seawater Reverse Osmosis (SWRO) and 4500 m³/day Multi-stage Flash (MSF) distillation units, is being set up at Kalpakkam, near the Madras Atomic Power Station (MAPS). The construction of both these units has resulted in many challenges, imposing severe constraints as they are being retrofitted to the existing power plant. The steam supply ...

  • Wind Energy Production Estimates: Moving Beyond Time Averages

    No need to be a statistician to see that averages are often useful to compare different things. And yet, they often fall short as a true measure of performance. For instance, we use averages to compare the current weather against the climate normals or to get a sense of how our favorite sport team or player is doing. Team (player) statistics are a concise way of combining the scores from many ...

  • Incident in the Forsmark 1 nuclear power plant in 2006: analysis of communication issues between the plant and the operating company of the power grid

    Previous studies of the Forsmark incident from 25 July 2006 emphasised a need to improve integration and communication between the nuclear plants and the operating company of the power grid. This paper aims to better understand why communication issues occurred and what improvements are needed. For these purposes, communication issues were analysed in the context of knowledge management, more ...

  • Some advantages of nuclear fuel in spherical form for nuclear power plants

    This paper presents the pre-eminent features of a new generation of nuclear reactors in comparison with existing generations, such as safety operation, non-release of radioactive materials into the environment under any conditions, non-proliferation of nuclear weapons, and suitability for developing countries. The paper also presents some results on the physical features related to fuel burn-up, ...

  • Preventing the loss of knowledge in nuclear power plants

    Preventing the loss of nuclear knowledge has become an important concern for the atomic energy industry. A great number of nuclear workers are getting close to the retirement age and there are not enough young qualified people to replace them. It is necessary to identify the key skills to replace senior engineers, managers and experienced workers. This paper proposes a matrix for capturing the ...

  • Reflections on regulatory oversight of nuclear power plants

    A regulatory body acts as a representative for society to ensure that the operation of nuclear facilities do not introduce any undue threats. Typical regulatory tasks include the definition of safety requirements, the inspections needed to ensure that they are adhered to and the imposing of sanctions if violations are detected. Regulatory oversight is anchored in national legislation, which is ...

  • Countering security risks to nuclear power plants

    Between 1972 and 2007, altogether 17 major terror attacks or acts of sabotage were carried out against Nuclear Power Plants (NPPs). None of them resulted in an uncontrolled radioactive release. In order to reduce the security risk to NPPs due to terrorists in the future, preemptive measures are necessary to identify their motivation, incentives, and operational and logistical capabilities to ...

  • BBA emergency pump units for a nuclear power plant

    Following the Fukushima nuclear disaster in 2011, safety regulations at many nuclear plants have been considerably tightened, this has led to an increased demand for fire fighting pump systems. These systems must comply with extremely strict requirements and regulations. Working closely together with the Belgian distributor Rental Pumps, BBA Pumps has recently completed one of the most demanding ...

  • Completion of Belene Nuclear Power Plant: project perspectives

    The development of Belene NPP began with site selection in the 1970s, site characterisation in 1980–1981, and a decision to proceed in 1981. Construction was suspended for financial reasons in 1991. Now the state authorities have taken steps to continue the project. Despite the lengthy study period and the subsequent legislative changes, the evaluations indicate that Belene is a suitable NPP ...

  • New decommissioning system for nuclear power plants in Japan

    The subject matter of this paper discusses the new decommissioning system for nuclear power plants in Japan, including the system for the disposal of demolition waste and the decommissioning cost allowance system. The Nuclear Regulations Law, established in 1957, ordering that decommissioning be carried out, it was naturally impossible to set proper safety regulations. While the present safety ...

  • Quick response to assist nuclear power plant

    A US nuclear plant and their engineering contractor were faced with an unexpected challenge in the course of design work regarding installation of an emergency steam dump sparger in the plant’s Low Pressure (LP) condenser. During pre-outage reviews of the planned installation, it was found that an existing partition plate running nearly the length of the condenser was obstructing access. ...

  • Safety assessment for the deficient operation data in the gas-cooled nuclear power plants for hydrogen production

    The probabilistic safety assessment (PSA) is investigated in the case of the operational data shortage which is characteristic of the passive system in gas-cooled nuclear power plants (NPPs). Therefore, it is difficult to make a quantification of the PSA. One of the solutions is to compare the passive system and the active system. Using this comparison, one can find the priority of the passive ...
