| need for unilateral
approval of international shipments; B(M) refers to the need for multilateral
approval of international shipments. There is no distinction made
in how packages with these designations may be used in domestic transportation.
To determine their distinction for international transportation, see
DOT regulations in Title 49, CFR, Part 173. A Type B package approved
before September 6, 1983, was designated only as Type B. Limitations
on its use are specified in Title 10, CFR, §71.19.

This definition applies only to shipments of LLRW shipped to a Texas
LLRW disposal facility.

of this subsection in effect on or after June 30, 1983 (see Title
10, CFR, Part 71, revised as of January 1, 1983), and constructed
before July 1, 1985; a special form encapsulation designed in accordance
with the requirements of this subsection in effect on or after March
31, 1996 (see Title 10, CFR, Part 71, revised as of January 1, 1996),
and constructed before April 1, 1998; and
(D) special form material that was successfully tested
before September 10, 2015, in accordance with the requirements of
Title 10, CFR, §71.75(d) in effect before September 10, 2015
may continue to be used. Any other special form encapsulation must
meet the specifications of this definition.
(42) Specific activity of a radionuclide--The radioactivity
of the radionuclide per unit mass of that nuclide. The specific activity
of a material in which the radionuclide is essentially uniformly distributed
is the radioactivity per unit mass of the material.
(43) Spent nuclear fuel or spent fuel--Fuel that has
been withdrawn from a nuclear reactor following irradiation, has undergone
at least one year's decay since being used as a source of energy in
a power reactor, and has not been chemically separated into its constituent
elements by reprocessing. Spent fuel includes the special nuclear
material, byproduct material, source material, and other radioactive
materials associated with fuel assemblies.
(44) Surface contaminated object (SCO)--A solid object
that is not itself classed as radioactive material, but which has
radioactive material distributed on any of its surfaces. A SCO shall
be in one of the following two groups with surface activity not exceeding
the following limits:
(A) SCO-I--A solid object on which:
(i) the non-fixed contamination on the accessible surface
averaged over 300 square centimeters (cm2 )
(or the area of the surface if less than 300 cm2 )

(iii) the non-fixed contamination plus the fixed contamination
on the inaccessible surface averaged over 300 cm2 (or
