Drawings and documents

All design installation drawings and documentation including calculations. 

The water pipes have no connection. Paradoxically, they end in the above mentioned ventilation outlets, and can only have been installed after the removal of the ventilators installed there. There are, of course, shower rooms in these buildings, but in a very different location (see Fig. 17). The shower installations once in existence there, however, have been entirely dismantled. Since the doors to these rooms are open, any visitor may examine this peculiar construction. The original German drawings and documents of this building do not indicate that these pipes were installed during the German occupation, which means that they were probably installed after the war for an unknown reason. 

Identify, obtain, copy and organize the necessary drawings and documents for the review, for each team member (drawings and documents to be obtained from the Project Manager). 

Supply required accurate/up-to-date drawings and documents to the Team Leader (Table 6 provides a listing of ideal data requirements for a facility or system review during the design phase of the project). 

The construction documentation package comprises the instrument installation specification, drawings, and documentation listed in Appendix 23E, Instrument Installation Specification. During this phase and thereafter, it is important that the drawing register for the manufacturing process is maintained on-site and that only the latest revisions of drawings are used. 

The detailed specifications for the process streams and the equipment are set. All of the drawings and documents required by construction contractors and equipment vendors are prepared. Another cost estimate determines whether to proceed with a request to the business and legal departments to call for bids for plant construction. Construction cost estimates present another decision to proceed with the project. 

Documentation can be divided into drawings and documents, some of which are listed in Appendix E. 

Contracts were awarded in March 2000, and preliminary EDPs were drafted by the technology providers in June 2000. Each EDP includes drawings and documentation, a preliminary hazards analysis, and projected life-cycle costs and schedules for the technology package to be implemented at a particular site. The final EDPs were released in December 2000. Experimental tests to support the EDPs were begun in June 2000, but some had not been completed when this report was prepared. Einal reports are expected to be published in mid-2001. 

Gathering and analysis of the design drawings and documents. This activity is frequently difficult because of the incomplete availability of documents. It is therefore sometimes necessary to reconstruct layout or other information by inspection. 

The next step is the Design Qualification (DQ), in which the purchase is justified and the design (when it is custom-made) of the equipment is approved, including drawings and documentation. It is important to prepare the first edition of the URS before agreement with the supplier and to finalise it in connection with the DQ at the latest. 

HAZOP study for procedure This is normally a detailed method and should be properly defined. This study is usually carried out by a well-balanced team from different disciplines. The information required includes but is not limited to procedure definitions, up-to-date P IDs, and other relevant drawings and documents. Also the aim of the study (depth of study and major area of interest such as HSE, accident, etc.) needs to be well defined before starting a step-by-step procedure. Each stage/step and action is examined with the guide word to identify meaningful deviation for analysis for hazard identification. In the case of a HAZOP study for procedure, human error is an important factor. 

Full CHAZOP The main procedure is to study the system with the help of guide words and questiormaire, discussed in Clause 1.5.4 in detail. The designer presents the required information to the team in the form of various drawings and documents so that the study can be carried out. As before, such a complete... 

Drawings and documents that should be included in the design study, with particular reference to ... 

Ihe early attempts to keep track of parts, drawings and documents centred around a list of components, the drawings using to manufacture and the documents written to maintain, all written down at the time of design and manufacture. These were known as Build Specifications and Spares lists and were the only source of information available. Still in existence today, they prove to be very valuable in identifying parts and drawing, on many of BR s older rolling stock and infrastructure. 

As a result of BR s extensive telecommunications network, access to the mainframe is possible almost anywhere in the country. The PADS system has approximately 3,000 users in over 250 locations and now contains over 1 million records and 4 million cross references. This allows users to locate the correct part, drawing and document required to carry out a specific task quickly and easily, at the touch of a button. 

Drawing and document control is discussed in Section 5.5 of this report. 

The criteria for determining the adequacy of the SRS drawing and document control program for restart are described below. 

WSRC has established a formal program for drawing and document control as discussed below. 

The CACMP (Reference 1) contains a broadly defined scope that includes control of documentation associated with reactor systems important to safety, documentation for other reactor systems, structures and equipment important to long-term satisfactory performance, and documentation for the reactor control room simulator. The scope also contains a table that lists the 25 K-Reactor systems important to safety and denotes the 6 initial systems to be evaluated as part of the Technical Baseline Program. The criterion to describe the scope of the program and identify the types of drawings and documents to be controlled is met. 

The RRD CMPP also contains a task for the self-evaluation of the document control program. Including user compliance. While not an explicit restart criterion, this performance feedback loop gives added assurance that the drawing and document control program can be made to function as designed. 

Based on the above evaluation, the DOE staff concludes that WSRC has established a formal program for the control of drawings and documents that satisfies the restart criteria. 

In the case of missing drawings and documentation, the functional diagram preparation is recommended as an efficient aid in repair work. vs. the traditional draftsman approach.
