# §53.800. Facility licensees for self-reliant-mitigation facilities.

- (a) A commercial nuclear plant is a self-reliant-mitigation facility if the NRC determined as part of its approval of the OL or COL for that plant that its design demonstrates compliance with the criteria in [paragraphs (a)(1)](#a-1) though (a)(5) of this section. A self-reliant-mitigation facility is of a class, based upon the similarity of operating and technical characteristics of the plants in the class, such that its licensee must comply with the requirements of [§§ 53.800 through 53.820](/cfr/10/53.800..53.820.md) in lieu of those in [§§ 53.760 through 53.795](/cfr/10/53.760..53.795.md).
  - (1) The safety performance criteria of §§ [53.210](/cfr/10/53.210.md) and [53.220](/cfr/10/53.220.md) must be met without reliance upon human action for credited event mitigation.
  - (2) The results of the probabilistic risk assessment (PRA), other systematic risk evaluations, or a combination thereof required by [§ 53.450(a)](/cfr/10/53.450.md?p=a) must demonstrate that the evaluation criteria for the events analyzed in accordance with [§ 53.450](/cfr/10/53.450.md) will be met without reliance on human actions to achieve acceptable event mitigation.
  - (3) The functional requirements analysis and function allocation performed under [§ 53.730(d)](/cfr/10/53.730.md?p=d) must demonstrate that functions required for safety are not reliant upon credited human action.
  - (4) The plant response to events analyzed under [§ 53.450](/cfr/10/53.450.md) must rely exclusively on safety features and characteristics that will neither be rendered unavailable by credible human errors of commission or omission nor credibly require manual human operation in response to equipment failures. Compliance with this [paragraph (a)(4)](#a-4) may be achieved through the use of SSCs that function through inherent characteristics or that have engineered protections against human failures.
  - (5) Assessments of credited human actions within the analysis of design-basis accidents (DBAs) and across the range of LBEs other than DBAs do not identify important human actions needed to ensure appropriate defense in depth is provided, as required by [§ 53.250](/cfr/10/53.250.md).
- (b) [Reserved]
