REQUEST FOR ADDITIONAL INFORMATION 6-CONCERNING REACTOR SAFEGUARDS BRANCH REVIEW

)

0F CHAPTER 1, AMENDMENT NO. 12

)

0F-COMBUSTION ENGINEERING SYSTEM 80+ DESIGN, CESSAR-DC PROJECT NO. 675 500.1 There is no indication in this chapter of wherein the Severe Accident Policy and the unresolved generic issues will be addressed.

500.2 Section 1.2-2. indicates that the descriptions of the Nuclear Power Module (NPM) and the Interfaces are sufficient for evaluation of the essentially complete plant. Neither Table 1.2-1, the CESSAR scope for NPM, nor Table 1.2-2, the matrix of Interface sections, includes the security system. Yet:

(a) Section 13.6 of NUREG-0800 includes review of the layout of the plant and other design features and equipment arrangements intended to provide protection of vital equipment against acts of radiological sabotage.

(b) The physical barrier guidance in Regulatory Guide 5.65 should be considered during design of structures that contain equipment designated as vital equipment.

(c) A protected source of power for security lighting and access control systems should be considered during design of on-site electric power systems.

(See NUREG/CR-1327 Security Lighting Planning Document for Nuclear Fixed Site Facilities.)

500.3 Table 1.8-8, the list of applicable Regulatory Guides addressed in the System 80+ design, does not include RG 5.65.
