Here is what the House and Senate Reports says about nuclear thermal propulsion:

Quote from: page 61 of the House Report
Nuclear thermal propulsion technology.—The recommendation includes no less than $35,000,000 for nuclear propulsion technologies for space transportation and exploration. NASA shall provide a report to the Committee within 180 days of enactment of this Act on ongoing nuclear propulsion research, how NASA intends to employ this technology to support various exploration programs, and a comparison of nuclear propulsion and use to other forms of propulsion, in terms of speed and ease of construction.

Quote from: page 105 of the Senate Report
Nuclear Propulsion.—NASA is continuing its work to develop the foundational technologies and advance low enriched uranium nuclear thermal propulsion systems that can provide significantly faster trip times for crewed missions than non-nuclear options. The Committee provides $28,900,000 above the request for ongoing nuclear thermal propulsion technologies for space transportation and exploration. NASA shall update its report to the Committee within 180 days of enactment of this act on ongoing nuclear thermal propulsion research and how the research into this technology supports NASA’s exploration programs

There is also wording related to inter-stellar propulsion research in the House Report:

Rep Culberson uses part of his 2 min on H flr to spprt approps bill to say NASA will develop interstellar prop for the 2069 mission he wants

Quote from: page 61 of the House Report
Interstellar propulsion research.—Current NASA propulsion investments include advancements in chemical, solar electric, and nuclear thermal propulsion. However, even in their ultimate theoretically achievable implementations, none of these could approach cruise velocities of one-tenth the speed of light (0.1c), nor could any other fission-based approach (including nuclear electric or pulsed fission). The Committee encourages NASA to study and develop propulsion concepts that could enable an interstellar scientific probe with the capability of achieving a cruise velocity of 0.1c. These efforts shall be centered on enabling such a mission to Alpha Centauri, which can be launched by the one-hundredth anniversary, 2069, of the Apollo 11 moon landing. Propulsion concepts may include, but are not limited to fusion-based implementations (including antimatter-catalyzed fusion and the Bussard interstellar ramjet); matter-antimatter annihilation reactions; multiple forms of beamed energy approaches; and immense ‘sails’ that intercept solar photons or the solar wind. At the present time, none of these are beyond technology readiness level (TRL) 1 or 2. The NASA Innovative Advanced Concepts (NIAC) program is currently funding concept studies of directed energy propulsion for wafer-sized spacecraft that in principle could achieve velocities exceeding 0.1c and an electric sail that intercepts solar wind protons. Over the past few years NIAC has also funded mission-level concept studies of two fusion based propulsion concepts. Therefore, within one year of enactment of this Act, NASA shall submit an interstellar propulsion technology assessment report with a draft conceptual roadmap, which may include an overview of potential advance propulsion concepts for such an interstellar mission, including technical challenges, technology readiness level assessments, risks, and potential nearterm milestones and funding requirements.
