Claim 10:
11. A perforating gun assembly comprising:
a fluid-disabled detonator positioned in the perforating gun assembly, the fluid-disabled detonator comprising:
a shell comprising a closed end, an open end, a hollow interior extending between the closed end and the open end, and one or more fluid ports extending through a wall of the shell into the hollow interior;
a non-mass explosive body disposed within the hollow interior, the non-mass explosive body comprising a head portion, a skirt portion opposite the head portion, a varying diameter bore extending along a longitudinal axis of the non-mass explosive body, a transverse bore intersecting the varying diameter bore, and a primary explosive embedded in a portion of the body, wherein each of the varying diameter bore and the transverse bore is in fluid communication with the one or more fluid ports;
a main explosive load disposed within the hollow interior between the closed end of the shell and the non-mass explosive body;
a cylindrical plug positioned at the open end of the shell and at least partially disposed in the hollow interior of the shell; and
a printed circuit board secured to a first portion of the cylindrical plug and disposed in the hollow interior of the shell,

wherein, in the event of unintentional leakage of a fluid into the perforating gun assembly, the one or more fluid ports facilitate communication of the fluid into the shell, and wherein the one or more fluid ports in combination with the varying diameter bore and the transverse bore are configured to introduce the fluid into the non-mass explosive body to disable the detonator.
