COMPARISONS WITH ANSI N AND ISO Vienna, Austria June 2014 VIENNA INTERNATIONAL CENTRE Presented By R. D. (Donny) Dicharry, President HIGHLIGHTS OF DRAFT ANSI N43.9 Source Production & Equipment Company, Inc. (SPEC) St. Rose, Louisiana USA INTERNATIONAL ATOMIC ENERGY AGENCY RADIATION SAFETY IN INDUSTRIAL RADIOGRAPHY TECHNICAL MEETING ON

Specify quality assurance program requirements for entities that engage in the design, manufacture, testing or repair of industrial gamma radiography equipment and source changers QUALITY ASSURANCE Revise qualification requirements for associated equipment REVISE QUALIFICATION REQUIREMENTS Use clear, objective terms that will facilitate compliance. CLEAR, OBJECTIVE TERMS PRIMARY OBJECTIVES

The ISO 3999 was used as a reference document during the revision; initially ISO and then ISO later in the process. The subcommittee sought to harmonize with ISO-3999 as much as practical. REFERENCE APPROVAL NUCLEAR REGULATORY COMMISSION The NRC has indicated their intention to incorporate this edition into regulation. The Working Group consisted of equal representation from manufacturers, users and regulators.

ANSI N ISO ANSI N43.9 DRAFT COMPARISONS WITH ANSI N AND ISO HIGHLIGHTS OF DRAFT ANSI N43.9 RADIATION SAFETY IN INDUSTRIAL RADIOGRAPHY TECHNICAL MEETING ON This International Standard specifies the performance, design and test requirements of apparatus for gamma radiography with portable, mobile and fixed exposure containers of the various categories defined in Clause 4. The standard includes the qualification requirements for those who engage in the design, fabrication, assembly, testing, repair or modification of industrial gamma radiography equipment or source changers. SCOPE

ANSI N ISO ANSI N43.9 DRAFT COMPARISONS WITH ANSI N AND ISO HIGHLIGHTS OF DRAFT ANSI N43.9 RADIATION SAFETY IN INDUSTRIAL RADIOGRAPHY TECHNICAL MEETING ON Gamma Radiography System. All components necessary to make radiographic exposures, including the exposure device, source assembly, control, and other components associated with positioning the source such as source guide tubes, exposure head, and collimators, if used. DEFINITIONS apparatus for industrial gamma radiography apparatus including an exposure container, a source assembly, and as applicable, a remote control, a projection sheath, an exposure head, and accessories designed to enable radiation emitted by a sealed radioactive source to be used for industrial radiography purposes Industrial Gamma Radiography System: All integral components necessary to perform industrial radiography, including the exposure device, source assembly, and as applicable, associated equipment.

ANSI N ISO ANSI N43.9 DRAFT COMPARISONS WITH ANSI N AND ISO HIGHLIGHTS OF DRAFT ANSI N43.9 RADIATION SAFETY IN INDUSTRIAL RADIOGRAPHY TECHNICAL MEETING ON DEFINITIONS Output Activity: The exposure rate of the sealed source divided by the gamma constant (See table below). The activity of the source shall be determined by measuring its output at 1 m and expressing its activity in curies (becquerels) derived from the following values:

ANSI N ISO ANSI N43.9 DRAFT COMPARISONS WITH ANSI N AND ISO HIGHLIGHTS OF DRAFT ANSI N43.9 RADIATION SAFETY IN INDUSTRIAL RADIOGRAPHY TECHNICAL MEETING ON DEVICE CLASS & CATEGORY Category X: Apparatus for gamma radiography designed for special applications where the unique nature of the special application precludes full compliance with this International Standard, for example: self propelled intra- tubular gamma radiography apparatus (pipe-line crawler); gamma radiography apparatus for underwater use. The exposure container shall comply with this International Standard to the maximum extent possible. Category X: Equipment for industrial gamma radiography designed for special applications where the unique nature of the special application precludes full compliance with ANSI/HPS N43.9, for example, self-propelled industrial gamma radiography equipment (pipe-line crawlers). The industrial gamma radiography equipment shall comply with this standard to the maximum extent possible.

ANSI N ISO ANSI N43.9 DRAFT COMPARISONS WITH ANSI N AND ISO HIGHLIGHTS OF DRAFT ANSI N43.9 RADIATION SAFETY IN INDUSTRIAL RADIOGRAPHY TECHNICAL MEETING ON GENERAL DESIGN REQUIREMENTS Exposure devices shall be designed with due regard for the conditions which may be encountered during use. (Corrosion, water, mud, sand, or other foreign matter.) Apparatus for industrial gamma radiography shall be designed for the conditions likely to be encountered in use. NOTE If feasible, a test for continued operation under environmental conditions of moisture, mud, sand and other foreign materials, will be developed and will be issued as an addendum. Radiography equipment shall be designed for the conditions likely to be encountered in use when the equipment is used and maintained in accordance with the manufacturer’s instructions. The design of the equipment shall minimize the effect of the environmental conditions of moisture, sand, mud, and other foreign matter that the equipment is likely to encounter during use.

ANSI N ISO ANSI N43.9 DRAFT COMPARISONS WITH ANSI N AND ISO HIGHLIGHTS OF DRAFT ANSI N43.9 RADIATION SAFETY IN INDUSTRIAL RADIOGRAPHY TECHNICAL MEETING ON GENERAL DESIGN REQUIREMENTS Wherever depleted uranium is used for shielding…. the source tunnel through the depleted uranium shall…. limit abrasion, corrosion and consequential deformation. Inspection and maintenance For Category II exposure devices that contain a depleted uranium shield the instructions shall include an inspection of the exposure device source path for wear- through to the shield in accordance with Appendix A.

ANSI N ISO ANSI N43.9 DRAFT COMPARISONS WITH ANSI N AND ISO HIGHLIGHTS OF DRAFT ANSI N43.9 RADIATION SAFETY IN INDUSTRIAL RADIOGRAPHY TECHNICAL MEETING ON GENERAL DESIGN REQUIREMENTS Limitation of abrasion shall be demonstrated by satisfactory performance of a test consisting of the examination of the simulated source assembly, to demonstrate that there is no abrasion of the source tunnel which could lead to contamination by depleted uranium. Use a swab to wipe the interior surface of the exposure device source path (S-Tube) Test the first swab for DU contamination. If the wipe test indicates DU contamination an inspection (e.g., visual inspection, eddy current, etc.) of the interior of the exposure device source path shall be performed. If the inspection indicates that the exposure device source path (S-Tube) is worn through to the DU shield the exposure device shall be removed from service.

ANSI N ISO ANSI N43.9 DRAFT COMPARISONS WITH ANSI N AND ISO HIGHLIGHTS OF DRAFT ANSI N43.9 RADIATION SAFETY IN INDUSTRIAL RADIOGRAPHY TECHNICAL MEETING ON TESTS Vibration-resistance test The purpose of the test is to determine the natural frequencies which are characteristic of the exposure container and to study the change in these natural frequencies in order to determine if the exposure container is able to withstand vibrations experienced during transportation.

ANSI N ISO ANSI N43.9 DRAFT COMPARISONS WITH ANSI N AND ISO HIGHLIGHTS OF DRAFT ANSI N43.9 RADIATION SAFETY IN INDUSTRIAL RADIOGRAPHY TECHNICAL MEETING ON ACCOMPANYING DOCUMENTS Certificates of the manufacturer With each apparatus, the manufacturer shall provide a certificate of conformity to show compliance with this International Standard

ANSI N ISO ANSI N43.9 DRAFT COMPARISONS WITH ANSI N AND ISO HIGHLIGHTS OF DRAFT ANSI N43.9 RADIATION SAFETY IN INDUSTRIAL RADIOGRAPHY TECHNICAL MEETING ON QUALITY ASSURANCE PROGRAM A quality-assurance programme, such as that specified in ISO 9000, ISO 9001 or ISO 9004 or the IAEA regulations STI-PUB 998 for the design, manufacture, testing, transport, inspection and documentation of all apparatus for industrial gamma radiography, shall be established. Those who engage in the design, fabrication, assembly, testing, repair or modification of radiography equipment or source changers shall operate under the control of a quality assurance (QA) program. The QA program shall include the requirements of 10 CFR Part 71 Subpart H, ISO 9001 or similar elements. Compliance with the QA program shall be certified by an independent entity.
