This document is Part 1 of GB/T 43257 "Safety Test Methods for Radioactive Material Transport Containers". GB/T 43257 has been released The following sections are included.

---Part 1. General provisions;

---Part 6. Heat resistance test.

Introduction

The inherent safety of radioactive material transport containers is a prerequisite for the safety of radioactive material transport and needs to withstand normal transportation conditions and transport Verification of various tests under accident conditions.

GB/T 43257 is aimed at various verification tests of different types of transport containers. It is necessary to clarify the status of the transport containers participating in the test and the detailed tests.

Conditions, test equipment and equipment, test implementation and testing, data processing methods, test qualification evaluation and many other specific contents, as This is an important supplement to the implementation of GB 11806-2019 "Regulations for the Safe Transportation of Radioactive Materials", making relevant test assessments more specific and standardized.

Therefore, the safety test method for radioactive material transport containers specifically guides various types of transport containers to carry out corresponding verification tests for the design of the containers.

It is of great significance in terms of planning, verification and evaluation.

GB/T 43257 is planned to consist of 11 parts.

---Part 1. General principles. The purpose is to clarify whether radioactive material transport containers will withstand normal transport conditions and transport accident conditions. Below are the general requirements for various tests.

---Part 2. Water spray test. The purpose is to standardize and guide radioactive material transport containers to withstand water spray tests under normal transport conditions. Test and assessment.

---Part 3. Accumulation test. The purpose is to standardize and guide radioactive material transport containers to withstand stacking tests under normal transport conditions. Test and assessment.

---Part 4. Drop test. The purpose is to standardize and guide radioactive material transport containers to withstand normal transport conditions and transport accidents.

Tests and assessments such as free fall, penetration and breakdown-tear under certain conditions.

---Part 5. Impact test. The purpose is to standardize and guide the impact test of radioactive material transport containers under transportation accident conditions. Test and assessment.

---Part 6. Heat resistance test. The purpose is to standardize and guide the heat resistance and heat resistance of radioactive material transport containers under transportation accident conditions. Strengthen heat resistance test assessment.

---Part 7. Water immersion test. The purpose is to standardize and guide radioactive material transport containers to withstand water immersion under transport accident conditions. There is no and enhanced water immersion test assessment.

---Part 8. Shielding test. The purpose is to standardize and guide radioactive material transport containers to withstand normal transport conditions and transport accidents. Shielding test after conditioning.

---Part 9. Leak test. The purpose is to standardize and guide radioactive material transport containers to withstand normal transport conditions and transport accidents. Leakage test under conditions.

---Part 10. Vibration test. The purpose is to standardize and guide the vibration test of the vibration effects of radioactive material transport containers Assessment.

---Part 11. Heat transfer test. The purpose is to standardize and guide the transport containers of radioactive items so that the effects of decay heat of the contents cannot be ignored. Heat transfer test assessment.

GB/T 43257.1 provides the sample, test items and sequence, test conditions, and instruments in the safety test method for radioactive material transport containers Basic requirements for equipment, testing and testing, test data processing, test conformity assessment, quality assurance and control, and test reporting. and water spray test, Stacking test, drop test, impact test, heat resistance test, water immersion test, shielding test, leakage test, vibration test, heat transmission test etc., together constitute a test method suitable for evidence collection and performance evaluation of radioactive material transport containers.

The terms and definitions defined in GB 11806 and the following apply to this document.

4 Samples

The specimen consists of the transport container and its contents and meets the following requirements.

a) The transportation container should have complete parts and components, without corrosion, deformation and other defects;

b) The contents to be contained in the transport container should be replaced by simulators with non-toxic, non-corrosive and other dangerous properties. The structure and rationale of the simulators should be The chemical properties should be designed to reflect the properties of the real contents based on the purpose of experimental verification;

c) If necessary, follow the requirements of GB/T 4857.1 for the deformed parts of the transport container that may be most severely damaged and focus on mark;

d) Necessary repairs made on the sample due to the installation of test sensors, test cable routing, and installation of test instruments and equipment.

Processing should be minimized and should not affect the sample test and assessment items.
