.W SM NG TC N 3.1 20555 Gexjj MASSACHUSETTS INSTITUTE OF TEGN0 LOGY DOCKET NO. 50-20 AMENOMENT TO FACILITY OPERATING LICENSE Amendment No. 17 License No. R-37 1.
The Nuclear Regulatory Comission (the Comissien) has found that:
A.
The application for amendment by Massachusetts Institute of Tech-nology (the license) dated Marcn 13, 1980, as supplemented tn October 10, 1980 co@ lies with the standards and requirements of the Atomic Energy Act of 1954, as amenced (the Act) and the Comission's rules and regulations set forth in 10 CFR Chapter I; B.
The facility will operate in conformity with the application, the provisions of the Act, and the rules and rgilations of the Commission, C.
There is reasonable assurance (i) that the activitie authorizec by this amendment can be conducted without endangering tha health and safety of the public, and (ii) that such activities will be conducted in cogliance with the Comission's regulations, D.
The issuance of this amendment will not be inimical to the comon defense and security or to the health and safety of the public; E.
The receipt, possession and use of the byproduct as authorized by this amendment will be in accordance with the Comission's regulations in 10 CFR Part 30, including 10 CFR Section 30.33 ;
F.
The issuance of this amendment is in accordance with 10 CFR Part 51 of the Comission's regulations and all applicable requirements have been satisfied; and G.
Publication of notice of this amendment is not required since it does not involve a significant hazards consideration nor amendment of a license of the type described in 10 CFR Section 2.106(a)(2).
2.
Accordingly, Paragraphs 2.B.(3) and 2.C.(2) of the Facility Operating License No. R-37 are hereby revised in their entirety to read as follows:
2.B.(3)
Pursuant to the Act and 10 CFR Part 30, " Rules of General Applicability to Licensing of Byproduct Materials", to possess and use a 150-curie antimony-beryllium sealed neutron sot.rce in connection with operation of the reactor; and to receive possess, use, and transfer byproduct materials activated in reactors other than the MIT reactor (for use in the hot cells)that are in solid form and have atomic numoers 3 through 33. The total inventory of this byproduct material shall not exceed 1,000,000 curies at any one time, and 4
so; 2110 74
e
. 2.C.(2) Technical Soecifications The Technical Specifications contained in Acpendix A, as revised througn Amt. :dment No.17, are hereby incorp-orated in the license.
The licensee shall operate the facility in accordance alth the Technical Specifications.
3.
This license amendment is effective as of the date of its issuance.

Whenever the hot cells are used the following shall be provided:
a.
no experiments shall be conducted in the het cells and on-going experiments shall be terminated when the contair. ment building and/or hot cell ventilation systens are shut down.
b.
the hot cell blower shall be interlocked with the containment building exhaust system bicwer. The hot cell bicwer shall auto-matically shut off when the main ventilation system bl wer or danpers are shut down.
c.
in event of a fire in the hot cell, the hot cell blowa shall be automatically shut off and an alarm snall sound in the hot cell area and the control rocm.
d.
a visual alarm in the hot cell area shall activate when the contain-ment building exhaust system is shutdown.
7.
Byproduct materials will be limited to atomic nunters 3 through 83 to solid form only. Additional qualifications are:
a.
a.
Total inventory of materials from other sources would not exceed 1,000,000 curi es.
b.
Inventory for any one sample or specimen would be limited to 10,000 curies.
c.
Each sample or specimen would be limited to a radiation flux of 1000 rads /hr., at one meter from an unshielded source.

the pressure relief system filters.
The monitors located in the exhaust stack are to cetermine whether any hign level release has actually taken
]
place.
Both the plenum gasecus and plenum particulate monitors have independent redundant systems. Two monitors in the ventilaticn exnaust stack back up one another, and hence, adequate protection will still be present if one monitor shculd fail.
When the containment ventilation system is shutdown, the exhaust for ventilating gases and particulates from the hot cell is lost, accordingly, experiments in the het cells shculd not be initiated or should be terminated until the containment ventilation system is operable as required.
In event of fire in the hot cells it is necessary to contain the fire within the hot cells.
In this event the hot cell blower that exhausts the at:rosphere from the hot cells shall be shutdown. The hot cell fire alarms sha.1 be connected to the Containment Building Fire Alarm System. An automatic fire extinguishing system in the hot cell shall be activated if the te@erature rises above a predetermined setpoint.
When the ccntainment building exhaust system is shutdown, it is necessary to alert any operators involved in the hot cell operations that those operations must be terminated until the containment bicwers are once more operable.
Accordingly, visual alarms will be located in the hot cell area.
At least one operating floor monitor is needed to insure that the general radiation levels in the occupied area around the reactor are within the limiting values established by 10 CFR 20.
