SUBJECT:
HUMAN FACTORS ENGINEERING ISSUES RELATED TO AP600 OPERATOR WORKSTATIONS AND COMPUTERIZED PROCEDURE SYSTEM
Dear Mr. Liparulo:
This is to document that the Human Factors Assessment Branch, as part of its continuing rt. view of AP600 inspectior,s, tests, analyses, and acceptance criteria (ITAAC), has identified two policy.
levelissues; one related to operator workstations and the other related to the use of the computerized procedure system.
Conceming the operator workstation:;, the Desig1 Description for Hurnan Factors Engineering (3.2) contained in the AP600 certified design material (CDM), revision 3, states that the main contrcl room includes two reactor operator workstations and one senior reactor operator workstation, and the remote shutdown room includes one reactor operator workstation. The staff has concluded that this level of detail, specified in the design description and ITAAC, is premature for the level of design description provided in the latest revision of the AP600 standard safety analysis report (SSAR), Specifically, the information provided in the SSAR is for an implementation plan and does not describe the design of the contiol room o remote shuidown room but rather presents a methodology for designing the facilities. Thus, there is insuffici~t technical ba:ls to allow the staff to make a safety det6rmination that two reactor operator v.orkstations and one senior reactor operator workstation in the main control room and one operator workstation in the remote shutdown room will provide for safe operation of the AP600 plant under all required conditions of operation. Unless the CDM design description and associated ITAAC is revised to eliminate specifying tiie number of workstations, the staff cannot accept the Westinghouse Human Factors Engineering ITAAC.
Conceming the use of the computerized procecure system, the staff continues to conclude that retorence to such a system in the SSAR is unacceptable. The staff sent a letter on the subject to West;nghouse on June 13,1997. The letter stated the reasons for the staff conclusions and options that Westinghouse had for correcting the problem. From subsequent conversations with Westinghouse, the staff understands that Westinghouse has decided to add a clarification to the SSAR. If Westinghouse inter)ds to use this option the staff believes that Westinghouse must make it clear in their SSAR that the computerized procedure system is not part of the AP600 design scope that the Nuclear Regulatory Commission is being asked to approve.
