Design revision

Figure 5 provides a blank table (eomplete with design revision seetion) used to perform a design FMEA. It forms a traeeable reeord of the design and its failure modes and assoeiated risks.

The use of RTMs is not limited to the lifetime of a project. They are equally useful for change management, determining the scope of testing to address design revisions. RTMs can also be used to support inspections later by quickly identifying where certain aspects of the system are tested. Traceability is one of the most important ways in which quahty can be built into software, and should always be checked by the auditor during Suppher Audits. 

The Risk Priority Number (RPN) is the pivotal column and set of numbers on the DFMEA worksheet. To calculate the RPN for each failure mode, multiply the scores for severity, occurrence, and detection. The higher the number, the higher the priority should be for design revisions or corrective actions. You can see in our example which failure modes have a higher priority of occurring and, therefore, are candidates for immediate corrective action. 

All field failure data must be reviewed keeping in mind design revisions. When significant design changes are made, then field experience with previous designs should not be considered.

In 1986, a detailed design revision for improving the reactor was made in a joint effort between CCHEN and JEN. During the major modification of the reactor, which ended in 1989, the initial 31 fuel assemblies had to be repaired and only 29 could be reassembled, resulting in a limitation imposed on the reactor power. Due to the limitations in the amount of fuel assemblies available, the operating reactor power was established as 2 MW. 

This chapter will help you design, revise, implement, and evaluate your safety and health training. It also provides information on OSHA requirements for training and tells you where to find further OSHA references and other assistance.

The negative information contained in these documents should be recorded in a comprehensive form (object, materials, fabrication, treatment, operational data, locality, description and cause of failure), evaluated either by corrosion experts or by a failure board, and filed for easy reference by aU design personnel. The reports can either be filed individually or together. Where a number of failure reports on a related subject accumulate, a corrosion failure index dealing with various sections of the problem or various parts of the utility is preferred. Where there is a considerable number of failures of a comparatively restricted and repetitive nature, it is desirable to record such information by electronic data processing. It is important that such information, in accurate form and preferably converted into a useful summary, be distributed as soon as possible to all interested personnel to be used either for design revision or maintenance programming.
