Content:
design approval, but is not intended to be included in the DCD (e.g., proprietary information), should be submitted as a separate report that is referenced in the appropriate section of the DCD. This information should be minimized because it may need to be resubmitted to the staff as part of a combined license application. 2. Treatment of Proprietary and Safeguards Information Because of the requirement of the Office of the Federal Register that all information incorporated into the design certification rule be publicly available, proprietary and safeguards information that is withheld from public disclosure cannot be included in the DCD. However, this information is part of the NRC staff's bases for its safety findings for the design, and the NRC considers this information to be a requirement for facilities that reference the design certification rule. Therefore, the proprietary and safeguards information that is withheld from public disclosure, or its equivalent, must be resubmitted as part of a COL application. The maximum use of publically available information in the application is strongly recommended to facilitate resolution of issues for future COL applicants and licensees. For example, upon close examination by the evolutionary plant designers, significant portions of proprietary information were able to be reclassified as non-proprietary. Also, for one design, the SSAR and DCD were prepared using publically available safeguards information. After determining what material cannot be included in the DCD, and to ensure that it is clear what is required as part of a COL application, the applicant should clearly indicate in the DCD any deletions of proprietary or safeguards information. The DCD should refer to the appropriate location of the proprietary or safeguards information residing in any separate, external documents. 3. Probabilistic Risk Assessment (PRA) Information For the evolutionary design reviews, industry requested deletion of certain design
