Page 1 of 1 Comments on the Kairos Power Hermes Test Reactor Construction Permit Draft Environmental Impact Statement Comment Number Draft Environmental Impact Statement Text and Location Comment 1
Page 2-3, Line 19: the offsite discharges would include 16 gpm from the bathrooms and 1 gpm from the decay heat removal system (DHRS).
The 1 gpm from the decay heat removal system is evaporated. If evaporation is included in this discharge summary, the staff may also want to consider the 34 gpm of evaporation from the chilled water system, per ER Figure 2.4-1.
2 Page 3-6, Line 27: The applicant has indicated that the Atlas facility would occupy no more than 30 ac of land on the site, located outside of the approximately 30 ac of land occupied by the Hermes facilities The Atlas facility location, within the Kairos property, has not been chosen yet. No land use conflict is expected. We suggest the language in the DEIS be altered to delete located outside of the approximately 30 ac of land occupied by the Hermes facilities 3
Page 3-13, Line 22: Intermittent use of propane fired heaters for the intermediate coolant located in the primary heat rejection system during maintenance activities This information was deleted from the ER in an enclosure to a letter dated February 18, 2022.
(ML22049B556) 4 Page 3-71, Line 18: A primary heat rejection system capture system for tritium separation from dry air in the cover gas; This information was deleted from the PSAR and the ER in enclosures to a letter dated February 18, 2022 (ML22049B556).
5 Page 3-79, Line 36: Additionally, as an indicator of the low risks from postulated accidents, the MHA dose at the LPZ is also below the annual radiation dose limits for individual members of the public of 100 mrem TEDE under 10 CFR 20.1301(a).
The MHA dose at the LPZ is below the annual dose limit values specified in 10 CFR 20.1301(a).
However, these limits are for annual effluent releases and are not applicable to MHA doses associated with postulated events in this or other applications. We believe the NRC staffs purpose in making this comparison is to demonstrate the fact that even postulated accident doses are below normal-operation limits, but we suggest some clarification.
6 Page 4-9, Line 23: The applicant did not provide cost (internal, external, fuel, waste disposal) information for the construction, operation, or decommissioning of the proposed project.
Financial information was provided as proprietary information in enclosure 4 with the PSAR submission dated September 29, 2021.
