tivities under this paragraph, to support 
and accelerate the decontamination of rel-
evant facilities managed by the Depart-
ment. 
(3) CLIMATE AND EARTH MODELING.—As part 
of the activities described in paragraph (1), the Di-
rector, in collaboration with the Advanced Scientific 
Computing Research program described in section 
606, shall carry out research to develop, evaluate, 
and use high-resolution regional climate, global cli-
mate, and Earth models to inform decisions on re-
ducing the impacts of a changing climate. Such 
modeling shall include, among other critical ele-
ments, greenhouse gas emissions, land use, and 
interaction among human and Earth systems. 
SEC. 606. ADVANCED SCIENTIFIC COMPUTING RESEARCH 
PROGRAM.

the Department. 
(c) RESEARCH TO SUPPORT ENERGY APPLICA-
TIONS.— 
(1) IN GENERAL.—As part of the activities au-
thorized under subsection (a), the program shall 
support research in high-performance computing and 
networking relevant to energy applications including 
modeling, simulation, and advanced data analytics 
for basic and applied energy research programs car-
ried out by the Secretary. 
(2) REPORT.—Not later than 1 year after the 
date of enactment of this Act, the Secretary shall 
transmit to the Congress a plan to integrate and le-
verage the expertise and capabilities of the program 
described in subsection (a), as well as other relevant 
computational and networking research programs 
and resources supported by the Federal Government,
