Technical safety equipment

A suitable maintenance strategy should be developed for equipment by considering the criticality and failure mode, and then applying a mixture of the forms of maintenance described above. In particular, the long-term cost of maintenance of an item of equipment should be estimated over the whole life of the project and combined with its capital cost to select both the type of equipment and form of maintenance which gives the best full lifecycle cost on a discounted basis), while of course meeting the technical, safety and environmental specifications. 

From a technical viewpoint, excessive expenditures for safety equipment to solve single safety problems may make the system unduly complex and consequently may cause new safety... 

A technical safety barrier represents technical equipment, whose function it is to arrest the accident/incident evolution so that the next event in the chain will not be realised. The human safety barrier is the suitable people, whose function it is to intervene and arrest the accident/incident evolution so that the next event in the chain will not be realised. The organizational safety barrier is the procedures, rules, guidelines, etc. present, which function to arrest the accident/incident evolution so that the next event in the chain will not be realised. In this thesis the latent conditions and precursors in an unfolding situation are considered to have three possible effects on the safety barriers negative, positive or none at all. 

In addition, prior to SIT departure a special committee performs complex check-up of SIT for purposes of physical protection of nuclear materials (control over technical condition, equipment and fire safety observance of security rules and anti-terrorist preparedness). 

An audit of manufacturing and control processes will include a thorough review of all of the documentation required to demonstrate that a product meets the requirements for its intended use, including requirements for marketing and consumer use, technical design and performance, regulatory and quality assurance, and product safety. Equipment systems will also be inspected. 

Technical safety measures have to assure safe service conditions or, if they are so designed, safety in accidents. The design of a technical system has to consider the right configuration of function units with components made from suitable materials, correctly dimensioned, and equipped with all necessary devices. The design and construction has to consider all relevant design loads. 

This paper first provides a brief description of the U.S. plutonium immobilization using ceramic processing. A systematic approach for identifying and solving possible technical safety issues is introduced in Section 3. Technical and other broad safety issues specifically associated with the ceramic processing for excess plutonium immobilization are summarized in Section 4. A brief conclusion is given in Section 5. It should be emphasized that the results are preliminary, since at this moment the details of the facility and equipment designs are not yet available. 

Based on the pre-conceptual designs of the U.S. ceramic process, a summary of the technical safety issues is given below. It should be emphasized that the results are preliminary and generic because the facility and equipment design details are not yet available. 

The necessary protective measures have to be implemented by safety equipment, which in turn has to be dimensioned on the basis of the expected technical demands. 

Standards. European harmonized standards provide specific technical safety/EMC design, testing and pass/fail rules for components, products, and machines. Standards are the cornerstone of the New Approach, and without them the Single Market could not function. The EU standards, referred to in the directives, provide a presumption of conformity for equipment manufactured in accordance with these standards. Without properly applying EU standards, equipment will not benefit from a presumption of conformity conferred by the use of such standards. 

Safety is a line responsibility that is shared by the operators, facility supervisor, facility manager. Director, and Vice President. The staff is procedurally trained to understand and obey the Technical Safety Requirements (TSRs) of the facility. If plant conditions change such that TSRs are threatened by operations, experiments, equipment failures or external forces, then operations are immediately terminated to minimize the possibilify of a TSR violation and a potential unanalyzed or unsafe condition. The Hot Cell Facility Periodic Maintenance/ Surveillance Operating Procedure (SNL 1997c) requires periodic inspection and checkout of important safety equipment and safety system settings to minimize the chance of "undetected" degradation of safety equipment that could lead to a safety function failure. 

Allowed Outage Time (AOT) is specified in Limiting Conditions for Operation in Technical Specifications as the maximum time for which certain safety equipment can be put out of the operation without the plant is put in a safer operating state. AOT covers one or more modes of plant operation and it is constant versus the plant configurations. In standard technical specifications, AOT is referred to as completion time. 

The surveillance requirements (SR), as stated in section 1, define in detail the periodic surveillance tests and are included within technical specifications (TS) of the NPP. The main purpose of this inclusion is to assure avaQabihty and operahdily of the NPP safety equipment during all modes of operation of the NPP.

Personal Mastery. Process safety is based on identifying process-related risks in advance and preventing accidents. Performance in this area is regularly reviewed using internal audits and official inspections. Technical safety systems and procedures, up-to-date protective equipment, and access to the appropriate safety data sheets are all used to ensure a high standard of health and safety ... 

Due to uncertain data, it is frequently not justified to view data obtained from quantitative analysis on the expected frequency or (he occurrence probability of undesired effects in systems as certain absolute quantities. In this case as well, relative comparison of different event progressions or technical constructions frequently provides valuable information. This also holds true when quantitative safety analysis is not applied to entire systems but only to specific safety equipment for the purpose of comparing various implementation alternatives,... 

European directives are an important instrument of the New Approach in the field of technical harmonisation and standardisation. They are intended to remove the technical barriers by harmonising product regulations and conformity evaluations. No specifications but only essential requirements restricted to the protection of health and safety of users and the protection of environment, are laid down in the New Approach directives. Up to 2000 some 20 directives have come into force. The directives cover products where safety aspects are relevant such as lifts, pressure equipment, explosion-proof materials, toys and personal safety equipment. 

The audit activities often find deficiencies in the completion of maintenance activities and missing links between equipment and the safety barriers (Ratnayake et al 2012). It is essential to know the links and interconnections between maintenance and technical safety disciplines. The safety analyses and identification of safety functions should be transferred to the maintenance engineers in order to classify specific equipment accordingly. Results of safety-related analyses performed by technical safety engineers should be prioritized over results of maintenance criticality analyses. Clear links should be established in order to ensure that one discipline s output can be used as input for other disciplines. The mandatory Performance Standards (PS) required by the PSA may be seen as a potential major link between safety and maintenance disciplines (Fig. 9). 

The information that was used for this simulation is generic data. That is to say, the information about the process unit is limited to an instrument count and the instruments were modeled with generic equipment models. This is the coarsest application of the Platypus software that we term the generic analysis . A detailed analysis is also possible. In that case, the total length of pipework, the number of connections to a vessel, the SIL level of technical safety barriers may be modeled to represent the unit as closely as possible. Historic failure data of the plant can also be implemented. This is possible because Platypus allows for the adaptation of the generic models on each level of detail of the model. This makes it very flexible but the workload associated with modeling an entire process plant (which may literally consist of thousands of pieces of equipment) may not be very practical. In addition, it may be hard to find relevant data. 

The implementation phase (5) is crucial to costs and on time commissioning of technical building equipment and the whole building. In this phase such fire safety services as construction supervision, quality assurance (51-53) and fire safety engineering methods (52-62) can dramatically reduce construction costs, enables the flexible use of the building and ensure the realization of planed life and fire safety. 

The miner s representatives right to pay for walk-around duties under the Mine Act covers inspections and investigations involving the enforcement of safety and health standards. Miners also can play a large role in technical consultations, equipment demonstrations, and discussions on research under the Mine Act and participate in these activities. 

Paperwork is both a Uxil and a torment in all commissioning. During mechanical completion specialized paperwork relating to units of equipment or components is needed, for technical, safety, contractual and legal purposes. 

During an outage, safety equipment may or may not be available, but almost certainly will depend on human interaction for its initiation. Administrative barriers like Technical Specification may be vague or non existent. The operating support fi om instrumentation to proeedures and training may be inadequate. The disturbances to normal operation are typically more Sequent than for the power operation and caused by different initiators, mainly human interaction. 

When handling such contaminated SFs care must be taken not to breathe in gaseous or dusty decomposition products. In case this cannot be achieved by technical safety measures like good ventilation, personal protective equipment must be worn. This personal protective equipment needs to include items of protection for the eyes, body and breathing. 

In situ pretreatment methods are limited due to a restricted accessibility to equipment because it is often not possible, too expensive, or too harmful to install complex technical devices and additionally necessary safety equipment.
