ions establish more specific criteria for accomplishing such changes. ( d ) ( 1 ) The licensee shall maintain records of changes in the facility, of changes in procedures, and of tests and experiments made pursuant to paragraph (c) of this section. These records must include a written evaluation which provides the bases for the determination that the change, test, or experiment does not require a license amendment pursuant to paragraph (c)(2) of this section. ( 2 ) The licensee shall submit, as specified in § 50.4 or § 52.3 of this chapter , as applicable, a report containing a brief description of any changes, tests, and experiments, including a summary of the evaluation of each. A report must be submitted at intervals not to exceed 24 months. For combined licenses, the report must be submitted at intervals not to exceed 6 months during the period from the date of application for a combined license to the date the Commission makes its findings under 10 CFR 52.103(g) . ( 3 ) The records of changes in the facility must be maintained until the termination of an operating license issued under this part, a combined license issued under part 52 of this chapter , or the termination of a license issued under 10 CFR part 54 , whichever is later. Records of changes in procedures and records of tests and experiments must be maintained for a period of 5 years.
