Control and verification

Management emphasises the importance of reporting all potential problems. The reporting is promoted through simple reporting routines and an efficient follow-up. All reports are assigned actions for follow-up with a responsible person and deadline. The database is used for the followup of actions. 

One of the safety officer s tasks is to assign a risk score to each reported event. The supervisors formerly carried out this scoring, but this routine was abandoned due to a reluctance to use high-risk scores. High-risk events are followed up closely by top management. Results and experiences of 

Problem-solving groups are employed in the development of remedial actions. The aim is to use the knowledge of the personnel directly involved to solve safety problems. 

Information is distributed through periodic summaries of accident statistics, status reports on safety measures, special reports, etc. There are different uses of this information such as input to decisions on remedial actions, evaluation of the effects of these actions, and monitoring of SHE performance. The database also provides mandatory reports on accidents to insurance companies and the authorities. 

The periodic summaries on accident statistics are distributed quarterly. They provide feedback on SHE performance to line management and the SHE organisation. Ymer s quarterly report contains control charts on the accumulated LTl-rate and the TRI-rate since the start of the year, distribution of accidents by accident type, injured part of body, etc. An edited summary of each accident case is also presented. The database helps in the production of standard reports and makes it possible to tailor these to the needs of each department.

The ability to analyze very small samples by NAA opens the possibility of following temporal changes in trace element concentrations in living subjects. Some essential elements such as Mn and Se display a considerable stability of their concentrations in human blood, whereas an element like As may change its concentration by two orders of magnitude as a result of food intake [22]. In addition, NAA is used for the determination of Cu in liver biopsies as a control and verification of the adequate treatment of Wilson disease. 

The VKR-MT is developed for a land-based NPP. Maximum use of the benefits provided by micro fuel elements in a pebble bed form makes it possible to develop a reactor design, in which the core operates for 10 years without reloading and shuffling of fuel, and the refuelling is performed once-at-a-time without opening the reactor vessel cover, through the use of special containers with fresh and spent micro fuel elements and a dedicated micro fuel element hydraulic transport system. From the standpoint of proliferation resistance, such technical feature is equivalent to an option of factory fabricated and fuelled reactor, but essentially simplifies the associated transport operations. The refuelling could be performed by a special team dispatched from a fuel factory and shall involve strict control and verification measures. 

Fuel assembly cutting is performed after the fuel assemblies are withdrawn from the reactor, which could enhance the effectiveness of the IAEA control and verification, since in this way it is possible to measure all fuel elements and exclude the possibility of an undeclared replacement of intermediate rows of fuel elements for fuel elements with fertile material. With this approach, the accounting unit is an individual fuel element and not a fuel assembly ... 

A system hazard analysis (SHA) does the same thing as an SSHA except that it identifies hazards across subsystem boundaries and interfaces. It looks at system-level hazards. An SHA also should list hazard controls and verifications.

FIGURE 13.12 Results of predictive control of for free radical polymerization of Am in semibatch operation. In batch mode, decreases monotonically in time. By computing conditions for isoreactivity (Equation 13.63c) constant during the reaction was achieved. By operating Am flow into the reactor in the flooded regime (Equation 13.63b), a predictable increase in during the semibatch reaction was achieved. Adapted with permission from Kreft T, Reed WF.

In design, the EPC contractor must develop SHE management systems to control and verify compliance with all contractual requirements. They shall be based on the principles and requirements in the quality management standard family ISO 9000. Design reviews, risk and reliability analyses, inspections and tests are examples of control and verification activities. Norskoil s project team participates in some of the activities and carries out independent control and verification activities as well. 

The NORSOK standard S-002 on Working environment reflects these basic SHE management principles. Chapter 4 of the standard lists the various types of control and verification activities that must be performed by the contractor to cover all essential working environment factors. We here find requirements as to coarse and detailed job-safety analysis and as to quantitative risk analysis. In Chapter 5 we find the working environment requirements as to design.

The responsibihties of the plant managers encompass implementation of the safety policy of the operating organization, establishment and perpetuation of a strong safety culture, and control and verification of safety related activities. 

The procedures discussed above satisfy Charlotte Criterion MS-21.1 which calls for the implementation of a formal design change process. They also satisfy Charlotte Criterion DB-2.11 in that they establish a method by which modifications to seismically qualified systems will be reviewed for impact, control, and verification. These procedures also require the establishment and control of specific documentation and require design control for Technical Baseline systems as well as the balance of systems in the facility. Changes are to be reviewed in accordance with RDP 12.03, "Unreviewed Safety Question Initial Screening and Safety Evaluation Procedure".
