Summary

The Secretary must send Congress a yearly report with the President’s budget that explains how the Spallation Neutron Source Project is doing. The report must say which project milestones were met, compare real costs to the estimates, and note any changes in cost or schedule. The law also defines key names: SING (the new major instrument package), SNS power upgrade (the power improvements in the Department’s 20-year plan), SNS second target station (the second target in that 20-year plan), Spallation Neutron Source Facility (the finished user research facility at Oak Ridge National Laboratory), and Spallation Neutron Source Project (Department Project 99–E–334 at Oak Ridge). The Secretary must also make an operational plan to use the Facility fully for materials, nanoscience, and other Office of Science work. The plan must cover a fair, peer-reviewed user program with technical help for outside researchers, ongoing instrument development, and schedules and costs, as much as possible, for full operations, instruments (including SING), the power upgrade, and the second target station. Funding is authorized as follows: $1,411,700,000 total for the life of the Project ($1,192,700,000 for construction and $219,000,000 for other costs); SING gets $75,000,000 for each of fiscal years 2007 through 2009; the SNS power upgrade gets $160,000,000 (available until spent); and if the Department’s heavy water supply is too low, $12,000,000 is authorized for fiscal year 2007.

(b)Spallation Neutron Source Project

(1)In general

The Secretary shall submit to Congress, as part of the annual budget request of the President submitted to Congress, a report on progress on the Spallation Neutron Source Project.

(2)Contents

The report shall include for the Project—

(A)a description of the achievement of milestones;

(B)a comparison of actual costs to estimated costs; and

(C)any changes in estimated Project costs or schedule.

(c)Spallation Neutron Source Facility plan

(1)In general

The Secretary shall develop an operational plan for the Spallation Neutron Source Facility that ensures that the Facility is employed to the full capability of the Facility in support of the study of advanced materials, nanoscience, and other missions of the Office of Science of the Department.

(2)Plan

The operational plan shall—

(A)include a plan for the operation of an effective scientific user program that—

(i)is based on peer review of proposals submitted for use of the Facility;

(ii)includes scientific and technical support to ensure that external users, including researchers based at institutions of higher education, are able to make full use of a variety of high quality scientific instruments; and

(iii)phases in systems upgrades to ensure that the Facility remains at the forefront of international scientific endeavors in the field of the Facility throughout the operating life of the Facility;

(B)include an ongoing program to develop new instruments that builds on the high performance neutron source and that allows neutron scattering techniques to be applied to a growing range of scientific problems and disciplines; and

(C)address the status of and, to the maximum extent practicable, costs and schedules for—

(i)full user mode operations of the Facility;

(ii)instrumentation built at the Facility during the operating phase through full use of the experimental hall, including the SING;

(iii)the SNS power upgrade; and

(iv)the SNS second target station.

(d)Authorization of appropriations

(1)Spallation Neutron Source Project

There is authorized to be appropriated to carry out the Spallation Neutron Source Project for the lifetime of the Project $1,411,700,000 for total project costs, of which—

(A)$1,192,700,000 shall be used for the costs of construction; and

(B)$219,000,000 shall be used for other Project costs.
