vibratory ground motion for which safety class items are designed to remain functional. [DOE

O 6430.1A]

143.

DESIGN FEATURES. The design features of a nuclear facility specified in the technical safety

requirements that, if altered or modified, would have a significant effect on safe operation. [10

CFR 830.3]

144.

DESIGN LIFE. The time period during which satisfactory performance can be expected for a

specific set of service conditions. [DOE O 5480.EIA] [EH62dd1]

145.

DESIGNEE. A person delegated responsibility or authority by a formal memorandum or letter.

[DOE O 5480.31] [EH62dd1]

146.

DETERMINISTIC METHOD. The technique in which a single estimate of parameters is used

to perform each analysis. To account for uncertainty, several analyses may be conducted with

different parameters. [DOE G 420.1-2]

147.

DETONATION. A violent chemical reaction within a chemical compound or mechanical

mixture involving heat and pressure. A detonation is a reaction that proceeds through the

reacted material toward the unreacted material at a supersonic velocity. The result of the

chemical reaction is the exertion of extremely high pressure on the surrounding medium, forming

a propagating shock wave that is originally of supersonic velocity. When the material is located

on or near the surface of the ground, a detonation is normally characterized by a crater. [DOE

M 440.1-1]

148.

DIRECTOR. Unless otherwise indicated, the Director, Office of Contractor for Employee

DISCRIMINATION or DISCRIMINATORY ACTS. Discharge, demotion, reduction in pay,

coercion, restraint, threats, intimidation, or other similar negative action taken against a
