15. Start-up Reports
Three months after completion of requisite initial startup and power escalation testing of the reactor, or nine months after initial criticality, a written report is submitted to the chartering or licensing authorities.
The report shall include a summary of the following :
Description of measured values of operating conditions or characteristics obtained and comparison of these values with design predictions or specifications.
Descriptions of major corrective actions taken to obtain satisfactory operation.
Re-evaluation of safety analysis where measured values indicate substantial variance from those values used in the Safety Analysis Report.  
TM on the Draft SG on Operating Experience Feedback for Nuclear Installations, 8-12 Dec. 2014, Vienna, Austria

16. Periodic Operation Reports
Routine semester reports covering the activities of the reactor facility during the previous calendar year are prepared within one month following the end of each semester year. Each annual operating report shall include the following information :
A narrative summary of reactor operating experience including the energy produced by the reactor or the hours the reactor was critical, or both.
The unscheduled shutdowns including, where applicable, corrective action taken to preclude recurrence.
Tabulation of major preventive and corrective maintenance operations having safety significance.
Tabulation of major changes in the reactor facility and procedures.
A summary of the nature and amount of radioactive effluents released or discharged to the environments beyond the effective control of the owner operator.
A summarized result of environmental surveys performed outside the facility.
A summary of exposures received by facility personnel and visitors where such exposures are greater than 25 % of that allowed or recommended.

17. Nuclear Material Reports
This annual routine report regarding to the activity of Nuclear Material Accountancy is made in order to meet the Safeguard agreement to the IAEA.
This report include the following information :
Inventory of nuclear material in each KMP
Inventory change of nuclear material in MBA RI-C
Nuclear material balance closing in MBA RI-C

18. Occurrence Reports
In the case of safety significant occurrence, malfunction of the safety system, violation of safety limits or even an accident shall be reported to the Regulatory Body within no more than 24 hours by telephone/telegraph etc.
Whereas the written report shall be submitted within 14 days.
TM on the Draft SG on Operating Experience Feedback for Nuclear Installations, 8-12 Dec. 2014, Vienna, Austria

19. Other Reports
The below reports shall be submitted in written to the Regulatory Body within 30 days.
Permanent changes in the facility organization.
Significant changes or discovery of errors in the Safety Analysis methods or different performance of the safety.
System previously described in the Safety Analysis Report
TM on the Draft SG on Operating Experience Feedback for Nuclear Installations, 8-12 Dec. 2014, Vienna, Austria

20. Sample report for Core #85
11 malfunction/abnormals which force the reactor to scram or unscheduled shutdown. (4 of it due to electricity supply)
112 abnormals/low level events.
All the above problem can be solve directly by the Center for MPR-GAS.
Apparent causes was found, root cause analysis need to be improved/stressed!

21. Internationally  IRS-RR
Comply with the Incident Reporting System for Research Reactor (IRS-RR) from IAEA.
Center for Multipurpose Reactor act as the local coordinator
Nuclear Regulatory Body (BAPETEN) act as the National coordinator.
Criteria of the reported events:
Unusual events
The important and serious unusual events
The unusual event that is caused by previous similar events

22. get best practices from other member state,
From sharing to using!
Basically we have data/records from the operating experiences (internally or externally).
How it contribute to improve safety of the research reactor operation, particularly, due to aging of MPR-GAS?
How it contribute to improve the research reactor design ?
Related with our agendas:
redesign the TRIGA-MARK 2MW using the MPR-GAS fuel.
Experimental Power Reactor project.
So, we really interested to involve in the improvement of this OE Safety Guide,
get best practices from other member state,
and use it!
