# §45J. Credit for production from advanced nuclear power facilities

- (a) **General rule—** For purposes of [section 38](/usc/26/38.md), the advanced nuclear power facility production credit of any [taxpayer](/usc/26/1313.md?p=b) for any taxable year is equal to the product of—
  - (1) 1.8 cents, multiplied by
  - (2) the kilowatt hours of electricity—
    - (A) [produced](/usc/26/864.md?p=a) by the [taxpayer](/usc/26/1313.md?p=b) at an advanced nuclear power facility during the 8-year period beginning on the date the facility was originally placed in service, and
    - (B) sold by the [taxpayer](/usc/26/1313.md?p=b) to an [unrelated person](/usc/26/971.md?p=f) during the taxable year.
- (b) **National limitation—**
  - (1) **In general—** The amount of credit which would (but for this subsection and [subsection (c)](#c)) be allowed with respect to any facility for any taxable year shall not exceed the amount which bears the same ratio to such amount of credit as—
    - (A) the national megawatt capacity limitation allocated to the facility, bears to
    - (B) the total megawatt nameplate capacity of such facility.
  - (2) **Amount of national limitation—** The aggregate amount of national megawatt capacity limitation allocated by the Secretary under [paragraph (3)](#b-3) shall not exceed 6,000 megawatts.
  - (3) **Allocation of limitation—** The Secretary shall allocate the national megawatt capacity limitation in such manner as the Secretary may prescribe.
  - (4) **Regulations—** Not later than 6 months after the date of the enactment of or any amendment to this section, the Secretary shall prescribe such regulations as may be necessary or appropriate to carry out the purposes of this subsection. Such regulations shall provide a certification process under which the Secretary, after consultation with the Secretary of Energy, shall approve and allocate the national megawatt capacity limitation.
  - (5) **Allocation of unutilized limitation—**
    - (A) **In general—** Any unutilized national megawatt capacity limitation shall be allocated by the Secretary under [paragraph (3)](#b-3) as rapidly as is practicable after December 31, 2020—
      - (i) first to facilities placed in service on or before such date to the extent that such facilities did not receive an allocation equal to their full nameplate capacity, and
      - (ii) then to facilities placed in service after such date in the order in which such facilities are placed in service.
    - (B) **Unutilized national megawatt capacity limitation—** The term “unutilized national megawatt capacity limitation” means the excess (if any) of—
      - (i) 6,000 megawatts, over
      - (ii) the aggregate amount of national megawatt capacity limitation allocated by the Secretary before January 1, 2021, reduced by any amount of such limitation which was allocated to a facility which was not placed in service before such date.
    - (C) **Coordination with other provisions—** In the case of any unutilized national megawatt capacity limitation allocated by the Secretary pursuant to this paragraph—
      - (i) such allocation shall be treated for purposes of this section in the same manner as an allocation of national megawatt capacity limitation, and
      - (ii) [subsection (d)(1)(B)](#d-1-B) shall not apply to any facility which receives such allocation.
- (c) **Other limitations—**
  - (1) **Annual limitation—** The amount of the credit allowable under [subsection (a)](#a) (after the application of [subsection (b)](#b)) for any taxable year with respect to any facility shall not exceed an amount which bears the same ratio to $125,000,000 as—
    - (A) the national megawatt capacity limitation allocated under [subsection (b)](#b) to the facility, bears to
    - (B) 1,000.
  - (2) **Phaseout of credit—**
    - (A) **In general—** The amount of the credit determined under [subsection (a)](#a) shall be reduced by an amount which bears the same ratio to the amount of the credit (determined without regard to this paragraph) as—
      - (i) the amount by which the reference price (as defined in [section 45(e)(2)(C)](/usc/26/45.md?p=e-2-C)) for the calendar year in which the sale occurs exceeds 8 cents, bears to
      - (ii) 3 cents.
    - (B) **Phaseout adjustment based on inflation—** The 8 cent amount in [subparagraph (A)](#c-2-A) shall be adjusted by multiplying such amount by the inflation adjustment factor (as defined in [section 45(e)(2)(B)](/usc/26/45.md?p=e-2-B)) for the calendar year in which the sale occurs. If any amount as increased under the preceding sentence is not a multiple of 0.1 cent, such amount shall be rounded to the nearest multiple of 0.1 cent.

    the eligible project [partner](/usc/26/761.md?p=b) specified in such election, and not the qualified public entity, shall be treated as the [taxpayer](/usc/26/1313.md?p=b) for purposes of this title with respect to such credit (or such portion thereof).

  - (3) **Special rules—**
    - (A) **Application to partnerships—** In the case of a credit under [subsection (a)](#a) which is determined at the [partnership](/usc/26/761.md?p=a) level—
