SEC. 208. MODIFICATIONS TO SPECIAL RULES FOR NUCLEAR DECOMMISSIONING 
              COSTS.

    (a) Repeal of Limitation on Deposits Into Fund Based on Cost of 
Service; Contributions After Funding Period.--Subsection (b) of section 
468A is amended to read as follows:
    ``(b) Limitation on Amounts Paid Into Fund.--
            ``(1) In general.--The amount which a taxpayer may pay into 
        the Fund for any taxable year shall not exceed the ruling 
        amount applicable to such taxable year.
            ``(2) Contributions after funding period.--Notwithstanding 
        any other provision of this section, a taxpayer may pay into 
        the Fund in any taxable year after the last taxable year to 
        which the ruling amount applies. Payments may not be made under 
        the preceding sentence to the extent such payments would cause 
        the assets of the Fund to exceed the nuclear decommissioning 
        costs allocable to the taxpayer's current or former interest in 
        the nuclear power plant to which the Fund relates. The 
        limitation under the preceding sentence shall be determined by 
        taking into account a reasonable rate of inflation for the 
        nuclear decommissioning costs and a reasonable after-tax rate 
        of return on the assets of the Fund until such assets are 
        anticipated to be expended.''.
    (b) Clarification of Treatment of Fund Transfers.--Subsection (e) 
of section 468A is amended by adding at the end the following new 
paragraph:
            ``(8) Treatment of fund transfers.--If, in connection with 
        the transfer of the taxpayer's interest in a nuclear power 
        plant, the taxpayer transfers the Fund with respect to such 
        power plant to the transferee of such interest and the 
        transferee elects to continue the application of this section 
        to such Fund--
                    ``(A) the transfer of such Fund shall not cause 
                such Fund to be disqualified from the application of 
                this section, and

                from such Fund, or be includible in gross income, by 
                reason of such transfer.''.
    (c) Treatment of Certain Decommissioning Costs.--
            (1) In general.--Section 468A is amended by redesignating 
        subsections (f) and (g) as subsections (g) and (h), 
        respectively, and by inserting after subsection (e) the 
        following new subsection:
    ``(f) Transfers Into Qualified Funds.--
            ``(1) In general.--Notwithstanding subsection (b), any 
        taxpayer maintaining a Fund to which this section applies with 
        respect to a nuclear power plant may transfer into such Fund up 
        to an amount equal to the excess of the total nuclear 
        decommissioning costs with respect to such nuclear power plant

                life (within the meaning of subsection (d)(2)(A)) of 
                the nuclear power plant beginning with the taxable year

                deduction was previously allowed or a corresponding 
                amount was not included in gross income. For purposes

                transfer shall be treated as being from previously 
                deducted or excluded amounts to the extent thereof.

                        or loss shall be recognized on any transfer 
                        permitted by this subsection.

                        transfer permitted by this subsection, the 
                        amount of the deduction shall be the adjusted 
                        basis of such property.

        apply to any transfer unless the taxpayer requests from the 
        Secretary a new schedule of ruling amounts in connection with

        other provision of law, the taxpayer's basis in any Fund to 
        which this section applies shall not be increased by reason of 
        any transfer permitted by this subsection.''.
            (2) New ruling amount to take into account total costs.--
        Subparagraph (A) of section 468A(d)(2) is amended to read as 
        follows:
                    ``(A) fund the total nuclear decommissioning costs 
                with respect to such power plant over the estimated 
                useful life of such power plant, and''.
    (d) Effective Date.--The amendments made by this section shall 
apply to taxable years beginning after December 31, 2003.
