California Code, Revenue and Taxation Code - RTC § 24690

(a) The provisions of Section 468A of the Internal Revenue Code, relating to special rules for nuclear decommissioning costs, shall be applicable, except as otherwise provided.

(b) The deduction allowed for the 1987 taxable year may include contributions to a fund that are required to bring the balance in that fund up to the balance it would have contained if allowable contributions had been made for the 1985 and 1986 taxable years.

(c) The provisions of Section 468A(e)(2) of the Internal Revenue Code, which impose a tax upon the gross income of the Nuclear Decommissioning Reserve Fund, shall be modified for purposes of this part to provide that a tax shall be imposed upon the gross income of that fund for any taxable year at a rate equal to the rate in effect for that taxable year under Section 23501. The income tax imposed upon the gross income of the fund by this section is in lieu of any other tax imposed by this part or Part 10 (commencing with Section 17001) upon or measured by that income.
