Applicable Regulatory Requirements and Guidance Documents

The NRC staff is reviewing the SHINE operating license application, which describes the SHINE irradiation facility, including the irradiation units, and radioisotope production facility, using the applicable regulations, as well as the guidance contained in NUREG-1537, Part 1, Guidelines for Preparing and Reviewing Applications for the Licensing of Non-Power Reactors, Format and Content, issued February 1996 (ADAMS Accession No. ML042430055), and NUREG-1537, Part 2, Guidelines for Preparing and Reviewing Applications for the Licensing of Non-Power Reactors, Standard Review Plan and Acceptance Criteria, issued February 1996 (ADAMS Accession No. ML042430048). The NRC staff is also using the Final Interim Staff Guidance

[ISG] Augmenting NUREG-1537, Part 1, Guidelines for Preparing and Reviewing Applications for the Licensing of Non-Power Reactors: Format and Content, for Licensing Radioisotope Production Facilities and Aqueous Homogeneous Reactors, dated October 17, 2012 (ADAMS Accession No. ML12156A069), and Final Interim Staff Guidance Augmenting NUREG-1537, Part 2, Guidelines for Preparing and Reviewing Applications for the Licensing of Non-Power Reactors: Standard Review Plan and Acceptance Criteria, for Licensing Radioisotope Production Facilities and Aqueous Homogeneous Reactors, dated October 17, 2012 (ADAMS

Enclosure 2

Accession No. ML12156A075). As applicable, additional guidance cited in SHINEs FSAR or referenced in NUREG-1537, Parts 1 and 2, or the ISG Augmenting NUREG-1537, Parts 1 and 2, has been utilized in the review of the SHINE operating license application.

For the purposes of this review, the term reactor, as it appears in NUREG-1537, the ISG Augmenting NUREG-1537, and other relevant guidance can be interpreted to refer to SHINEs irradiation unit, irradiation facility, or radioisotope production facility, as appropriate within the context of the application and corresponding with the technology described by SHINE in its application. Similarly, for the purposes of this review, the term reactor fuel, as it appears in the relevant guidance listed above, may be interpreted to refer to SHINEs target solution.

Chapter 4 - Irradiation Unit and Radioisotope Production Facility Description

The following regulatory requirement is applicable to RAIs 4a-15 through 4a-18:

Paragraph (b)(2) of Section 50.34, Contents of applications; technical information, of 10 CFR Part 50 requires, in part, that an FSAR include a description and analysis of the structures, systems, and components of the facility, with emphasis upon performance requirements, the bases, and the evaluations required to show that safety functions will be accomplished. The description shall be sufficient to permit understanding of the system designs and their relationship to safety evaluations.

RAI 4a-15The referenced embrittlement studies, The Effects of Neutron Radiation on Structural Materials, and Radiation Effects Design Handbook: Section 7, used for evaluating radiation damage in the SHINE target solution vessel (TSV) and the subcritical assembly support structure (SASS) use neutron fluence above 1 megaelectron volt (MeV) as a measure for radiation damage. However, the implicit correlation between fluence and displacement per atom in the radiation effects data may not be the same as the actual SHINE neutron spectrum because of the 14.1 MeV neutron source used in the SHINE irradiation units.

Provide a complete energy spectrum of neutrons expected in the limiting areas of the SHINE TSV and the SASS, including expected relative populations of thermal and fast neutrons that will contribute to radiation damage. The limiting areas depend on a combination of limiting local stresses during normal conditions and design basis events and the local radiation fluence. Provide spectrum diagrams, including comparison(s) to prototypical light water reactor spectrums, and accompanying descriptions demonstrating that the expected energy spectrums would not result in radiation damage, as supported by the referenced embrittlement studies.

This information is necessary for the NRC staff to determine the relevancy of the embrittlement studies used by SHINE to predict radiation damage in the SHINE TSV and SASS. Further, this information is necessary for the NRC staff to find that SHINE has included adequate descriptions and analyses of the structures, systems, and components of the facility to show that safety functions will be accomplished, consistent with the requirements of 10 CFR 50.34(b)(2).

RAI 4a-16In SHINE FSAR Section 4a2.4.1.1, Design Considerations, SHINE states, in part, the following:

Radiation effects and corrosion testing has been performed at Oak Ridge National Laboratory (ORNL) to determine the characteristics of stainless steel for TSV relevant conditions. The results of the radiation effects testing, corrosion testing, and literature data were used as input for the final TSV design.

However, SHINE does not describe the types and results of the corrosion and irradiation testing performed by ORNL. Further, SHINE does not adequately demonstrate within the FSAR how the TSV and SASS will fulfill their design basis requirements over their intended lifetimes. Therefore:

a) Identify the types and results of the corrosion and irradiation testing performed at ORNL on the TSV and SASS materials and how these test results have been used to demonstrate the adequacy of the TSV and SASS components over the components intended design lifetimes.

Provide relevant references to studies and reports used to support the evaluation of the adequacy of these components.

b) Demonstrate that the design requirements will be maintained over the intended operating lifetimes of the TSV and SASS by evaluating the potential effects of material degradation due to the operating environment (i.e., operating temperature, cooling water chemistry, and radiation damage).

This information is necessary for the NRC staff to determine that SHINE has included adequate descriptions and analyses of the structures, systems, and components of the facility to show that safety functions will be accomplished, consistent with the requirements of 10 CFR 50.34(b)(2).

RAI 4a-17SHINE FSAR Figure 4a2.7-1, Target Solution Vessel Heat Transfer Surfaces, shows that cooling channel 3 (CC3) provides forced water to cool the TSV outer wall. FSAR Chapter 4a2.7.3.1, General Characteristics, states, in part, that (CC3) is the annular gap between the TSV and the SASS inner baffle. FSAR Figure 4a2.7-1 shows a gap/area between the SASS inner baffle and the SASS inner wall that could create stagnant water flow zones that may subsequently lead to degradation (e.g., cracking) of the inner baffle and inner wall components.

However, the SHINE FSAR does not describe the impacts of such potential degradation on the ability of the primary closed loop cooling system (PCLS) and SASS to fulfill their design requirements over the intended service life.

Therefore, confirm whether stagnate flow zones are created in the area between the SASS inner baffle and SASS inner wall that may lead to degradation (e.g.,

cracking) of either component. If stagnate flow zones are created, demonstrate that the PCLS and SASS design requirements continue to be met over the intended service life of those components.

This information is necessary for the NRC staff to determine that SHINE has included adequate descriptions and analyses of the structures, systems, and components of the facility to show that safety functions will be accomplished, consistent with the requirements of 10 CFR 50.34(b)(2).

RAI 4a-18Paragraph (b)(6)(iv) of 10 CFR 50.34 requires that an applicants FSAR include information regarding the [p]lans for conduct of normal operations, including maintenance, surveillance, and periodic testing of structures, systems, and components.

Section 4a2.4.1.5, Chemical Interactions and Neutron Damage, of the SHINE FSAR states, in part, the following:

The TSV, TSV dump tank, TOGS, and associated components act as the PSB and are safety-related. Surveillance and inspection capabilities for these structures, systems, and components (SSCs) are provided in order to assess mechanical integrity and verify corrosion rates are acceptable. The surveillance and inspection program ensures the integrity of the PSB components is not degraded below acceptable limits due to radiation damage, chemical damage, erosion, pressure pulses, or other deterioration.

However, SHINE does not describe the surveillance, testing, and inspection program(s) that will be implemented to monitor the integrity of the TSV and SASS over the design life.

Provide descriptions of the following aspects of surveillance, testing, and inspection program(s) that will be in place to monitor the integrity of the TSV and SASS over the design life:

Surveillance Program: Describe the objectives of the surveillance program, identify the locations within the TSV containing surveillance specimens, and provide the bases for choosing these locations. Then, describe the surveillance program planned at each TSV surveillance location. This description should include the following information:

o Type, size, number, and purpose of each unique specimen-type o Extraction and testing periodicity for each unique specimen type

Testing and evaluation to be performed for each unique specimen type and the associated standards that will be used to govern the testing and evaluation.

Inspection Program: Describe the objectives of the inspection programs for the TSV and SASS, identify the planned inspection locations within the TSV and SASS, and provide the bases for choosing these locations. Then, describe the inspection program planned at each TSV and SASS location.

This description should include the following information:

o Inspection method(s) and associated periodicity o Inspection coverage (i.e., surface area or volume) o Applicable codes and standards governing the inspection methods and the interpretation of inspection results 5

o Accessibility constraints or challenges that may limit inspection coverage

The intended use of results from both the surveillance and inspection programs to update the initial programs, if necessary, should also be described.

This information is necessary for the NRC staff to determine that SHINE has the appropriate program(s) in place to monitor the integrity of the TSV and SASS consistent with the requirements of 10 CFR 50.34(b)(6)(iv).
