There are several other items to consider when pro­curing a computer system for the automation of a nuclear power plant. The specification should provide for ap­propriate vendor action on each item

(a) Acceptance Tests. The complex nature of a com­puter control system demands a close and continuing check on its operability. A thorough set of checkout programs should be run at the factory and again after delivery to the site to disclose any faults that might have occurred in transit. These tests must encompass all the requirements of the specification and will be time consuming and tedious

(b) Installation. It is impractical in a full-size power plant to require the control-system manufacturer to install his equipment. He will, however, be expected to supervise the placement of cabinets, interconnecting cables, and the running of final acceptance tests

(c) Training. There has been, to date, no surplus of experienced process programmers. The quality of program­ming and maintenance training that the system manu­facturer offers will depend on the availability of his personnel. It is advisable to leave the training schedule open to negotiation, within specified limits, to make best use of the teacher’s time. However, the specification should include a request for outlines of the training courses.

(d) Appendixes. A list of control-system inputs and outputs can be appended to the specification to aid the bidder in sizing the equipment required. A rough layout of the control console will also help him visualize the display configuration and perhaps offer suggestions for improve­ment A floor plan will aid in placing components and in determining the lengths of interconnecting cables.
