20.09.2013

Introduction SINAP has a irradiation program to get i-data for

material used in molten salt reactors. Metal and graphite ASTM standards will be used in all the material

properties measurement. Irradiation temperature is 650℃ Max dose for metal is 2.5×1019 n/cm2（ E >

0.1MeV） Max dose for graphite is 5×1020 n/cm2（ E >

0.1MeV）

Metal irradiation program Total samples = 136 Samples for irradiation = 46

Properties ASTMHardness ASTM E18-12, E10-12Fatigue ASTM E606/E606M-12

Graphite irradiation program Total samples = 312 Samples for irradiation = 94 + 94

Properties ASTM no. of samplesThermal diffusivity ASTM C714 16+16

Specific heat capacity ASTM E1269 16+16Bulk Density ASTM C559 16+16

Young's modulus ASTMC769 16+16Flexural strength ASTM C651 16+16Tensile strength ASTM D3967 30+30

Compressive strength ASTM C695 16+16CTE ASTM E228 16+16

Tensile strength Tensile strength sample size in ASTM is

too big for our irradiation program D3967 is for rock tensile strength Underestimate graphite tensile strength More experiment and

analytical/numerical studies. New ASTM standard for graphite tensile

strength?

DYM or SYM Gas cooled reactor: gas has no

mechanical effect on graphite. May not be true for molten salt reactor. 3 ways to do graphite irradiation

experiment for molten salt reactorsA. Not consider molten salt at allB. Graphite samples in a container with molten

salt and irradiate together.C. Force molten salt into graphite samples

before irradiation experiment.

Standard requires no liquid inside the samples!

After irradiation experiment to measure DYM at what temperature? High DYM at room temperature Virgin DYM at high temperature

Virgin graphite with molten salt

Virgin graphite without molten salt

Some thoughts ASTM Standards mainly for nuclear

graphite in gas cooled reactor. Nuclear graphite in molten salt reactor

may need NEW ASTM standards???

Thank you!
