ASTM D7301 - 11(2015)

Overview

ASTM D7301 - 11(2015) is a critical standard specification that outlines the requirements for nuclear graphite suitable for components subjected to low neutron irradiation doses. This standard is essential for ensuring the integrity and performance of materials used in nuclear applications, particularly in environments where exposure to neutron radiation is a concern.

Key Requirements

The standard specifies various properties and testing methods to evaluate the suitability of nuclear graphite. Key requirements include:

• Material Composition: The graphite must meet specific compositional criteria to ensure it can withstand low neutron irradiation.
• Mechanical Properties: The standard outlines the necessary mechanical properties, such as tensile strength and modulus of elasticity, which are critical for structural integrity.
• Thermal Properties: Thermal conductivity and thermal expansion characteristics are defined to ensure effective heat transfer and stability under operational conditions.
• Radiation Resistance: The ability of the graphite to maintain its properties post-irradiation is a key focus, ensuring long-term performance in nuclear environments.

Implementation Benefits
