H.R. 5391 would direct the Domestic Nuclear Detection Office in the Department of Homeland Security (DHS) to improve the documentation and evaluation of research and development projects. The department is currently carrying out activities similar to those required by the bill, and CBO estimates that implementing H.R. 5391 would not significantly affect DHS spending.
Because enacting the legislation would not affect direct spending or revenues, pay-as-you-go procedures do not apply. CBO estimates that enacting H.R. 5391 would not increase net direct spending or on-budget deficits in any of the four consecutive 10-year periods beginning in 2027.
H.R. 5391 contains no intergovernmental or private-sector mandates as defined in the Unfunded Mandates Reform Act and would not affect the budgets of state, local, or tribal governments.
