II. Background

The NRC is seeking public input on the major issues associated with its proposed policy and expectations on the secure uses of CsCl sources. As a first step, the NRC has prepared a draft policy statement, published June 29, 2010 (75 FR 37483), to address issues related to the safety and security of the International Atomic Energy Agency (IAEA) Category 1 and 2 CsCl sources.[1] The intent of this document is to foster discussion about the draft policy issues in the public meeting and to solicit comments on the draft policy statement.

Following the publication of the draft policy statement, additional information became available on security of radioactive sources. The Energy Policy Act of 2005 (Pub. L.109-58) named 12 Federal agencies and 2 State organizations to the interagency Radiation Source Protection and Security Task Force (Task Force) and named the NRC Chairman (or a designee) as its chairperson. The Task Force was charged with evaluating and providing recommendations to the President and Congress relating to the security of radiation sources in the United States from potential terrorist threats, including acts of sabotage, theft, or use of a radiological source in a radiological dispersal device. The first Task Force report was submitted in August 2006 (see​reading-rm/​doc-collections/​congress-docs/​correspondence/​2006/​president-08-15-2006.pdf). On August 11, 2010, the NRC transmitted to the President and Congress with the second report documenting the efforts of the interagency Task Force. The second report included 11 recommendations to improve source security in the U.S. (see​security/​byproduct/​2010-task-force-report.pdf).

III. Issues Paper on the Draft Policy Statement on the Protection of Cesium-137 Chloride Sources

The objective of the public meeting is to solicit stakeholder comments on the policy issues that are presented in the draft policy statement. The following format is used in the presentation of the issues. Each issue is assigned a number, a description of the policy issue, a list of panel presentations with subjects for volunteers to address in short overview-type presentations, and a list of questions for discussion by the general public. These issues, questions and factors are not meant to be a complete or final list, but are intended to initiate discussion. Interested stakeholders are welcome to recommend additions, deletions, or modifications to the key issues. The Commission will consider all public feedback when issuing the final policy statement. Meeting participants and commenters are encouraged to read the proceedings of the previous public meeting held in 2008 and the written comments that the NRC received. The documents are available at​materials/​miau/​licensing.html#cesium.

Issues for Discussion

Issue 1: The safety and security of risk significant sources is an essential part of the NRC's mission. Licensees have the primary responsibility to securely manage and to protect sources in their possession from misuse, theft, and radiological sabotage.

Panel presentations:

  • Outline of current security and control requirements.
  • Overview of security inspection findings by the NRC Regional offices.
  • Agreement State perspectives.

Participant deliberations:

  • What is the status and history of the current security requirements and programs to reduce the potential vulnerability of IAEA Category 1 and 2 sources?
  • What issues have licensees experienced when implementing the requirements?
  • What is the status of the NRC and Agreement State inspections designed to verify implementation of the requirements?

Issue 2: Adequate protection of public health and safety is maintained if CsCl sources are managed in accordance with the security requirements of the NRC and the Agreement States. The NRC monitors the threat environment and maintains awareness of international and domestic security efforts. In the event that changes in the threat environment necessitate regulatory action, the NRC is ready to issue additional security requirements to apply appropriate limitations for the use of CsCl in its current form.

Panel presentations:

  • Status of proposed 10 CFR Part 37 rulemaking, Federal Register Notice, June 15, 2010. (75 FR 33902)
  • Licensees perspective of security requirements for CsCl sources.
  • An overview of NRC's threat assessment process.
  • Overview of the Federal Bureau of Investigation (FBI) outreach efforts.

Participant deliberations:

  • Is security of CsCl sources adequately addressed by the current requirements?
  • Should CsCl sources receive special consideration?
  • How would the proposed Part 37 change the licensees' current/existing security measures for CsCl?
  • How do the FBI outreach efforts affect the protection measures in place for CsCl sources?
  • If needed, what additional cooperative efforts could be undertaken Start Printed Page 60151to enhance security or minimize the risk?

Issue 3: Could hardware improvements be made that would further mitigate or minimize the radiological consequences?

Panel presentations:

  • Irradiator manufacturers' presentation on safety features.
  • Overview of the Department of Energy (DOE)/National Nuclear Security Administration (NNSA) voluntary security enhancement program.
  • Licensee perspective of design changes.

Participant deliberations:

  • What is the status of current CsCl designs regarding security enhancements?
  • What are the benefits of the DOE/NNSA voluntary security enhancements and table-top exercises?
  • Are other isotopes being considered for the future production of existing designs?
  • Are new concepts being considered for new designs?

Issue 4: The development and use of alternative forms of cesium-137, while not required for adequate protection, is prudent and the NRC intends to monitor these developments closely.

Panel presentations:

  • Overview of feasible alternatives from the irradiator manufacturers' perspective and from the users' perspective.
  • Source manufacturers' presentation on new initiatives.
  • Dispersibility considerations.

Participant deliberations:

  • Are manufacturers currently considering the use of other forms of cesium (other than CsCl)? If yes, what alternatives are viable?
  • What is the status of new developments?
  • How can the effectiveness of new alternatives regarding solubility and dispersibility be measured?

○ What are the physical/chemical parameters?

○ How can risk reduction be quantified?

  • How to formalize solubility and dispersibility parameters?

Issue 5: CsCl enables three specific classes of applications that benefit society:

(a) Blood irradiation;

(b) Bio-medical and industrial research; and

(c) Calibration of instrumentation and dosimetry.

Panel presentations:

  • Equipment needs of the blood irradiation industry.
  • Conduct of bio-medical research in view of cesium-137 irradiation.
  • Issues in calibration technology in view of cesium-137 sources.
  • Status of alternative technologies.

Participant deliberations:

  • What impact does the Draft Policy Statement pose for each of these applications?
  • What is the licensees' experience in complying with the current security requirements in view of the three fields of applications?
  • What technological changes are anticipated in these applications regarding the use of cesium-137 sources?

Issue 6: The NRC recognizes that currently there is no disposal capability for commercial CsCl sources. The NRC considers it imperative to develop a pathway for the long-term storage and disposal of these sources whether or not there are alternatives developed.

Panel presentations:

  • Update from DOE on development of Environmental Impact Statement for a disposal facility.
  • Licensees' perspective on storage and disposal of CsCl sources.
  • Disposal of CsCl sources through DOE's Off-Site Recovery Program or Conference of Radiation Control Program Directors.

Participant deliberations:

  • What are the major issues for licensees (users of CsCl sources) regarding disposal of their sources?
  • What options are available?
  • What are the (security and cost) impacts of the current regulatory environment on licensees?

IV. Solicitation for Stakeholder Input
