Darrell and Drew

Below is question 9.3-1 for the Hermes 2 General Audit.The NRC staff would like to have a discussion regarding this question when Kairos is ready. Kairos is welcome to post an answer to this question on the Kairos electronic reading room, but no written answers are requested by the NRC staff at this time.

PSAR Section RequestRequest/Question Number 9.3, Pebble 9.3-1 Table 3.6-1, Structures, Systems, and Handling and Components, of the Hermes 2 preliminary safety Storage System analysis report (PSAR) identifies safety-related Full Core Offload and Spent Fuel Storage Rack and Spent Fuel Air Cooled Storage Rack structures, systems, and components (SSCs) that are associated with Section 9.3, Pebble Handling and Storage System. However, the remainder of the PSAR, including Section 9.3, does not contain any discussion of these SSCs.

1. Please clarify the role of these SSCs in the Pebble Handling and Storage System.

2. Identify and discuss the materials of construction and codes and standards to be used to design and construct these safety-related SSCs.

If you have any questions or need clarifications on the questions before the discussion, please do not hesitate to contact me. This email will be added to ADAMS and will be made public.
