Higher Burnup Workshop Schedules and What Constitutes a Quality Submittal July 30, 2020

• ATF Project Plan developed to meet timelines

• ATF, including HBU/IE, has a New Paradigm high priority for the NRC and and the industry, however, applications will receive the Cooperation same level of review

• Early and frequent communication is key

• NRC will be performing multiple parallel reviews Expectations,

• To allocate resources appropriately, NRC would like to:

- Communicate our expectations Schedules for submittals

- Discuss submittal and review

& schedules Timeliness - Discuss the amendment technology matrix

- Remain apprised of submittals and know how many licensees are expected to adopt

• Assertions or technical assumptions made in submittals need to be General supported by a safety and/or Expectations technical basis to ensure an for Quality efficient and timely review.

Submittals

• Need for continuous engagement

• Code/method suite validation

- NRC SRP guidance remains applicable

- Take note of past submittals and learn from them

• Criticality experiments Expectations

• Radiochemical assays for Quality

• Physics tests measurements

- Reassess and update uncertainty Part 50 quantification Submittals

• Spent Fuel Pool

- Exemptions and Criticality Safety

• Fuel Fragmentation, Relocation, and Dispersal (FFRD) Strategy must be addressed for HBU

• In October 2019, NRC examined critical path for in-reactor HBU/IE submittals to support industrys 2023 goal:

- Anticipated NRC review times:

Schedules

• 16 - 18 months Topical Reports (TR) and

• 12 months License Amendment Requests (LAR)

Timeliness for - Assumption: 18 month technology Part 50 launch date lead time Submittals - Submittal Time Frame:

• TRs - November 2020/January 2021

• LARs - June 2022 (?)

• Identification of facility changes and safety basis

• Criticality Safety

- Revision to criticality safety analyses or methodology Expectations - Updates to criticality code validation report for Quality

- Update to justification of minimum Part 70 margin of subcriticality Submittals

• Updates to the Integrated Safety Analysis including changes in items relied on for safety or accident sequences.

• Any impact on other technical or program areas identified in NUREG 1520.

• Criticality safety

- Adequate subcriticality safety margin for optimum moderation of proposed contents

- Adequate critical experiments and radiochemical assay measurements Expectations for criticality and depletion code validation for Quality

- May incorporate the use of sensitivity Part 71 / uncertainty analyses to show that existing critical experiments are Submittals for applicable for validating criticality calculation methodology Fresh Fuel

• Configuration control

- Adequate materials properties for ATF cladding materials

- Evaluate potential reconfiguration of the assemblies.

• In August 2019, NRC developed critical path for the front end of the fuel cycle to support Schedules industry's 2023 goal with IE:

and - Enrichment Facility LAR - August 2021 Timeliness for - UF6 transportation package -

Part 70 and 71 August 2021 Submittals - Fabrication Facility LAR -

October 2021

- Fresh fuel transportation package -

February 2022

• Radiation shielding

- Revised isotopic depletion and Expectations radiation dose analyses /

for Quality verified and validated code analyses Part 71 and Part 72

• Heat removal Submittals for - Revised decay heat analyses /

verified and validated code Spent Fuel analyses per current staff guidance

• Age-related phenomena

• HBU and IE are two technologies that are part of a host of ATF technologies License

• Matrix of possible license Amendment amendment technology Technology combinations.

Matrix ATF Type ATF Credit HBU Phase IE Cr-Coated Yes 1 No Cr-Coated No 2 Yes

• Most common?

• Timelines and subject matter of Industry- topical reports and license Anticipated amendment requests Submittals

• How many licensee are expected to adopt?
