Subject:
Response to Inspection Request Regarding Reactor Instrumentation of the MIT Research Reactor Docket No. 50-20, License No. R-37.
Gentlemen:
l During an NRC inspection of the MIT Research Reactor on 11-14 June,1996, it i
l was requested that an update and proposed schedule be made for certain instrumentation items which are scheduled to be replaced. This schedule is as follows:
1.
Area Radiation Monitoring System. An order was placed with the vendor for these units on 25 June 1996. The vendor has stated that the units will be delivered within ninety days of the date of order placement. It is anticipated that these units will be installed within an additional ninety days of receipt, or by 31 December,1996, if receipt of the units is timely.
In the interim, three new radiation monitors with control room remote indication have been installed and are fully functional. Two monitor the reactor floor and the other the primary chemistry room.
I l
2.
Effluent Monitors. Work has begun on fabrication of new meter faces to match instrument calibrations. The instruments will be installed once the calibration data is verified to be accurate. Installation will probably be possible by 31 March 1997.
3.
Nuclear Instrumentation. Three units were purchased and received from the vendor in spring of 1996. One unit was installed and tested, but showed problems in instrument response. These problems are being resolved with the vendor. It is not possible to give an accurate schedule until the problems are fully resolved. Because these units will eventually replace our current instruments in the MITR-II nuclear safety system, rushing their installation would not be in the best interest of reactor safety. 'lhe current nuclear gQQ}Q safety system is functioning properly and reliably.
