SUBJECT:

Experiments (continued)

o. Fueled experiments containing inventories of Iodine 131 through 135 greater than 1.5 Curies or Strontium 90 greater than 5 millicuries shall be in irradiation containers that satisfy the requirements of specification 3.6.i or be vented to the exhaust stack system through HEPA and charcoal filters which are continuously monitored for an increase in radiation levels.

p. Each non-fueled experiment shall be limited such that the inventory of Iodine 131 is not greater than 150 Curies.

q. Non-fueled experiments that are intended to produce Iodine 131 shall be processed in hot cells that are vented to the exhaust stack system through charcoal filters which are continuously monitored for an increase in radiation levels.

Bases

a. Specification 3.6.a restricts the generation of hazardous materials to levels that can be handled safely and easily. Analysis of fueled experiments containing a greater inventory of fission products has not been completed, and therefore their use is not permitted.

b. Specification 3.6.b is intended to reduce the likelihood of accidental voiding in the core or water annulus surrounding the center test hole by restricting materials which could generate or accumulate gases or vapors.

c. The limitation on experiment materials imposed by specification 3.5.c assures that the limits of Appendix B of 10 CFR 20 are not exceeded in the event of an experiment failure.

d. Specification 3.6.d is intended to reduce the likelihood of damage to reactor or pool components resulting from detonation of explosive materials.

e. Specification 3.6.e is intended to limit the experiments that can be moved in the center test hole while the reactor is operating, to those that will not introduce reactivity transients more severe than one that can be controlled without initiating safety system action (Ref. Add. 5 to HSR).

ATTACHMENT 10 TECHNICAL SPECIFICATION UNIVERSITY OF MISSOURI RESEARCH REACTOR FACILITY Number 3.6 Page 5 of 5 Date Amendment No.

SUBJECT:

Experiments (continued)

f. Specifications 3.6.f and 3.6.g provide guidance for experiment safety analysis to assure that anticipated transients will not result in radioactivity release and that experiments will not jeopardize the safe operation of the reactor.

g. Specification 3.6.h is intended to reduce the likelihood of reactivity transients due to accidental voiding in the reactor or the failure of an experiment from internal or external heat generation.

h. Specification 3.6.i is intended to reduce the likelihood of damage to the reactor and/or radioactivity releases from experiment failure.

i. Specification 3.6.j provides assurance that no chemical reaction will take place to adversely affect the reactor or its components.

j. Specification 3.6.k provides assurance that the integrity of the beamports will be maintained for all loop-type experiments.

k. Specification 3.6.1 assures that corrosive materials which are chemically incompatible with reactor components, highly flammable materials and toxic materials are adequately controlled and that this information is dissem-inated to all reactor users.

1. The extremely low temperatures of the cryogenic liquids present structural problems which enhance the potential of an experiment failure. Specifica-tion 3.6.m provides for the proper review of proposed experiments con-taining or using cryogenic materials.

in. Specifications 3.6.p and 3.6.q provide assurance that the processing of Iodine 131 can be performed safely and that equipment necessary for accident mitigation has been installed.

SUBJECT:

Iodine 131 Processing Hot Cells Applicability This specification shall apply to the limiting conditions of operation on the equipment needed to safely process Iodine 13 1.

Objective The objective of this specification is to reasonably assure that the health and safety of the staff and public is not endangered as a result of processing Iodine 131.

Specification

a. The facility ventilation exhaust system shall be operable when processing Iodine 131 in the Iodine 131 processing hot cells.

b. The facility ventilation exhaust system shall maintain the Iodine 131 processing hot cells at a negative pressure with respect to the surrounding areas when processing Iodine 131.

c. Processing of Iodine 131 shall not be performed in the Iodine 131 processing hot cells unless the following minimum number of radiation monitoring channels are operable.

Radiation Monitoring Channel Number

1. Stack Radiation Monitor I

2. Iodine- 131 Processing Hot Cells Radiation Monitor I Exception: When the required radiation monitoring channel becomes inoperable, then portable instruments may be substituted for the normally installed monitor in specification 3.11 .c.2 within one (1) hour of discovery for a period not to exceed one (1) week.

SUBJECT:

Iodine 131 Processing Hot Cells (continued)

d. At least three (3) charcoal filter banks having an efficiency of 99% or greater shall be operable when processing Iodine 131 in the Iodine 131 processing hot cells.

Bases

a. Operation of the facility ventilation exhaust system when processing Iodine 131 in the Iodine 131 processing hot cells ensures proper dilution of effluents to prevent exceeding the limits of 10 CFR 20 Appendix B.

b. Maintaining the Iodine 131 processing hot cells at a negative pressure with respect to the surrounding areas ensures safety for the facility staff.

c. The radiation monitors provide information to operating personnel regarding routine release of radioactivity and any impending or existing danger from radiation. Their operation will provide sufficient time to take the necessary steps to prevent the spread of radioactivity to the surroundings.

d. The potential radiation dose to staff and individuals at the Emergency Planning Zone boundary and beyond have been calculated following an accidental release of Iodine 131 activity. These calculations are based on the facility ventilation exhaust system directing all Iodine 131 processing hot cell effluents through charcoal filtration with an efficiency of 99% or greater prior to being released through the facility exhaust stack.

Obiective The objective of this specification is to reasonably assure proper operation of the equipment needed to safely process Iodine 131.

Specification

a. An operability test of the facility ventilation exhaust system shall be performed monthly.

b. The ability of the facility ventilation exhaust system to maintain the Iodine 131 processing hot cells at a negative pressure with respect to the surrounding areas shall be performed prior to any process (channel check).

c. The radiation monitors as required by specification 3.11 .c shall be calibrated on a semi-annual basis.

d. The radiation monitors as required by specification 3.11 .c shall be checked for operability with a radiation source at monthly intervals.

e. The efficiency of the Iodine 131 processing hot cells charcoal filter banks shall be verified biennially. It shall be verified that the charcoal filter banks have a removal efficiency of 99% or greater for iodine.

Bases

a. Experience has shown that monthly tests of the facility ventilation exhaust system are sufficient to assure proper operation.

Fueled experiments containing inventories of Iodine 131 through 135 greater than 1.5 Curies or Strontium 90 greater than 5 millicuries shall be in irradiation containers that satisfy the requirements of specification 3.6.i or be vented to the exhaust stack system through HEPA and charcoal filters which are continuously monitored for an increase in radiation levels.

p. Each non-fueled experiment shall be limited such that the inventory of Iodine 131 is not greater than 150 Curies.

q. Non-fueled experiments that are intended to produce Iodine 131 shall be processed in hot cells that are vented to the exhaust stack system through charcoal filters which are continuously monitored for an increase in radiation levels.

Bases

a. Specification 3.6.a restricts the generation of hazardous materials to levels that can be handled safely and easily. Analysis of fueled experiments containing a greater inventory of fission products has not been completed, and therefore their use is not permitted.

b. Specification 3.6.b is intended to reduce the likelihood of accidental voiding in the core or water annulus surrounding the center test hole by restricting materials which could generate or accumulate gases or vapors.

c. The limitation on experiment materials imposed by specification 3.5.c assures that the limits of Appendix B of 10 CFR 20 are not exceeded in the event of an experiment failure.

d. Specification 3.6.d is intended to reduce the likelihood of damage to reactor or pool components resulting from detonation of explosive materials.

e. Specification 3.6.e is intended to limit the experiments that can be moved in the center test hole while the reactor is operating, to those that will not introduce reactivity transients more severe than one that can be controlled without initiating safety system action (Ref. Add. 5 to HSR).

Experiments (continued)

f. Specifications 3.6.f and 3.6.g provide guidance for experiment safety analysis to assure that anticipated transients will not result in radioactivity release and that experiments will not jeopardize the safe operation of the reactor.

g. Specification 3.6.h is intended to reduce the likelihood of reactivity transients due to accidental voiding in the reactor or the failure of an experiment from internal or external heat generation.

h. Specification 3.6.i is intended to reduce the likelihood of damage to the reactor and/or radioactivity releases from experiment failure.

i. Specification 3.6.j provides assurance that no chemical reaction will take place to adversely affect the reactor or its components.

j. Specification 3.6.k provides assurance that the integrity of the beamports will be maintained for all loop-type experiments.

k. Specification 3.6.1 assures that corrosive materials which are chemically incompatible with reactor components, highly flammable materials and toxic materials are adequately controlled and that this information is dissem-inated to all reactor users.

1. The extremely low temperatures of the cryogenic liquids present structural problems which enhance the potential of an experiment failure. Specifica-tion 3.6.m provides for the proper review of proposed experiments con-taining or using cryogenic materials.

m. Specifications 3.6.p and 3.6.q provide assurance that the processing of Iodine 131 can be performed safely and that equipment necessary for accident mitigation has been installed.

Iodine 131 Processing Hot Cells Applicability This specification shall apply to the limiting conditions of operation on the equipment needed to safely process Iodine 131.

Obiective The objective of this specification is to reasonably assure that the health and safety of the staff and public is not endangered as a result of processing Iodine 131.

Specification

a. The facility ventilation exhaust system shall be operable when processing Iodine 131 in the Iodine 131 processing hot cells.

b. The facility ventilation exhaust system shall maintain the Iodine 131 processing hot cells at a negative pressure with respect to the surrounding areas when processing Iodine 131.

c. Processing of Iodine 131 shall not be performed in the Iodine 131 processing hot cells unless the following minimum number of radiation monitoring channels are operable.

Radiation Monitoring Channel Number

1. Stack Radiation Monitor I

2. Iodine-131 Processing Hot Cells Radiation Monitor I Exception: When the required radiation monitoring channel becomes inoperable, then portable instruments may be substituted for the normally installed monitor in specification 3.1 1.c.2 within one (1) hour of discovery for a period not to exceed one (1) week.

Iodine 131 Processing Hot Cells (continued)

d. At least three (3) charcoal filter banks having an efficiency of 99% or greater shall be operable when processing Iodine 131 in the Iodine 13 1 processing hot cells.

Bases

a. Operation of the facility ventilation exhaust system when processing Iodine 131 in the Iodine 131 processing hot cells ensures proper dilution of effluents to prevent exceeding the limits of 10 CFR 20 Appendix B.

b. Maintaining the Iodine 131 processing hot cells at a negative pressure with respect to the surrounding areas ensures safety for the facility staff.

c. The radiation monitors provide information to operating personnel regarding routine release of radioactivity and any impending or existing danger from radiation. Their operation will provide sufficient time to take the necessary steps to prevent the spread of radioactivity to the surroundings.

d. The potential radiation dose to staff and individuals at the Emergency Planning Zone boundary and beyond have been calculated following an accidental release of Iodine 131 activity. These calculations are based on the facility ventilation exhaust system directing all Iodine 131 processing hot cell effluents through charcoal filtration with an efficiency of 99% or greater prior to being released through the facility exhaust stack.
