QUALIFICATION LEVELS

VI-2100 GENERAL REQUIREMENTS

There are five qualification levels: Trainee, Level I,

Level II, Level III, and NDE Instructor. The skills and

by this Division, for their control and administration.

VI-3110 EXPERIENCE

The written practice shall specify the experience

requirements for each qualification level in accordance

with ANSI/ASNT CP-189 and the additional experience

that may be required for special visual examination

applications, such as in-vessel visual examination.

VI-3120 TRAINING

The written practice shall specify the training require-

ments for each qualification level in accordance withANSI/ASNT CP-189 and the additional training that

may be required for special visual examination applica-

tions, such as in-vessel visual examination.

VI-3130 EXAMINATIONS

The written practice shall specify the examination

requirements for each qualification level in accordance

with ANSI/ASNT CP-189.

visual examination defined in IWA-2211, IWA-2212,

and IWA-2213, or related experience in the applicable

method such as the following:

(1) for VT-1, experience as a weld examiner, AWS

CWI or AWS CAWI;

(2) for VT-1, experience in performing surface

examinations;

(3) for VT-2, experience in pressure tests;

(4) for VT-2, plant walkdown experience, such as

that gained by licensed and nonlicensed operators, local

leak rate personnel, system engineers, quality control

personnel, and nondestructive examination personnel;

(5) for VT-3, installation, maintenance, or exami-

nation of pumps, valves, or supports;

(6) for VT-1 and VT-3, experience in installation,

maintenance, or examination of RPV internals, or other

remote visual examination;

(7) for Level III, documented visual training or

examination activities; administration or development

of VT-1, VT-2, or VT-3 visual examination training

or examination programs; or experience as defined in

(1) through (6) above.

(b) Experience shall be documented by specific tasks

and disciplines, e.g., 10 hr VT-3 visual examination

of supports.

(c) No more than 50% of the required experience

for VT-1 visual examination shall be in surface exami-nation.

VI-4200 TRAINING

Visual examination personnel shall successfully com-

plete the training program outlined in Supplement 1.

312

Training received in other NDE disciplines or academic

training courses covering the topics in Supplement 1

may be credited toward certification. The hours of

training shall be in accordance with ANSI/ASNT
