NUREG-1537, Part 2 - NRC

CONDUCTOFOPsnEPAIoNS
* The applicant should have plans for receiving fuel, handling and performing
quality assurance checks on the new fuel, and loading fuel using a critical
expeinment.
* The critical mass (number of fuel elements) should be approximately
known and should be exactly determined by a systematic approach to a
critical experiment.
* Neutron detectors of high sensitivity and reliability may be used to
supplement the operational instrumentation during subcritical neutron
multiplication measurements.
* Measurements should be planned to measure operational reactor physics
parameters, such as shutdown reactivity (to confirm shutdown margin),
reactivity feedback coefficients, differential and integral control rod worths,
power level monitors, scram and interlock functions, fuel heat removal, and
related thermal-hydraulic parameters.
* Measured and predicted reactor physics parameters should be compared
and the results of the comparisons should be evaluated against
preestablished acceptance criteria.
* The control rods should be calibrated and excess reactivity should be
loaded systematically, in order to obtain accurate values..
* Thermal powerofthe reactor should be calibrated acceptably and
accurately to ensure compliance with the licensed power level limits and
any other license conditions, such as pulse characteristics.
* Area and effluent radiation surveys should be conducted to confirm
predictions of the radiological status of the facility.
* All instruments and components should be tested before routine operations
begin.
* Other systems dissed in the startup plan should be tested and found to
be operational before routine operations begin. - -
Revew Procedues
The reviewer should compare the startup plan submitted by the applicant with
startup reports, tecbhical specifications, other license conditions, startup plans, and
final reports from other similar reactor facilities. The reviewer should verify that
key facility parameters and conditions that are calculated and used in the
