nuclear reactors have waste disposal problems. reactors produce nuclear waste products emit dangerous radiation. because kill people touch them, cannot thrown away ordinary garbage. currently, many nuclear wastes stored in special cooling pools @ nuclear reactors.
united states plans move nuclear waste remote underground dump year 2010.
