( REQUEST FOR ADDITIONAL INFORMATION

! UNIVERSITY OF ILLINOIS AT URBANA-CHAMPAIGN ADVANCED TRIGA REACTOR DOCKET NO. 50-151

1. Please describe the current configuration of fuel in the facility. Where will fuel be stored

and what steps (either administrative or facility modification) will be taken to ensure that the reactor will not be operated.

, 2. TS 1.0, Definitions. Can a situation arise where the reactor is not secured and therefore l in operation? The definition of reactor secured includes the condition no work is in progress involving fuel. It is not clear from the definition that fuel movement within the l

l reactor pool or bulk shielding facility would not be considered operation with a need to meet all of the associated TS requirements. Many licensees have a second TS l definition where the reactor is secured when there is either insufficient moderator l available in the reactor to attain criticality (or the reactor core is subcritical to some l value) or there is insufficient fissile material present in the reactor core to attain criticality (or the reactor core is suberitical to some value) under optimum available conditions of l moderation and reflection.

3. TS 4.2.c. You are proposing to maintain a requirement for inspection of control rods.

l Will they be needed to maintain stored fuel in a subcritical condition?

4. Storage of fuel in the bulk shielding facility is different from the conduct of subcritical experiments or operation of the subcritical assembly. Please propose separate TSs that contain the requirements for storage of fuel in the bulk shielding facility and associated surveillance requiroments (also consider reference to TS 3.9 in TS 4.5).

5. TS 4.5. This TS refers to radiation monitoring equipment required by Section 3.4 of the TS. However, it appears that the radiation monitoring equipment in TS 3.4 is only required if the reactor is operating. Do you plan to keep this equipment operable during j fuel storage? If not, please justify.

l

6. TS 4.7 d. You have proposed a fuelinspection requirement where all elements would be inspected over a 10-year interval with approximately 10 percent of the elements being inspected each year. If deterioration or distortion is noted, you proposed moving the element to other storage. Please discuss the need to accelerate inspections to require inspection of all elements if deterioration or distortion is found during the routine inspection. Your proposed TS is worded such that only the elements in the subcritical assembly, not the poo!, are inspected over a 10-year period. Would it be simpler to say that fuel in wet storage will be inspected? What do you mean when you say an element will be removed to other storage?

7. TS 5.1 c. If reactor fuel is to be stored on the grid plate, how will this TS be applied?

l 8. TS 5.4. The TS states that the emergency cooling system will be capable of spraying j water over the fuel elements for an indefinite period is there any need for the system to i be operable at this time? How long afte the last shutdown of the reactor was the

system needed be to operable?

9. TS 6.1.2. This TS refers to minimum staffing at the Nuclear Reactor Laboratory. Is this the minimum staff assigned to the facility? Staffing normally refers to the minimum 4

i

L*,

l* 4.

l'.'

2 people that must be present in the facility. Please clarify. Your proposed TS refers to 1 ANSI /ANS-15.4. Are you referring to the 1988 version of the standard or will the i reference change as the standard is updated to the most current version that will be in effect? _ With your proposed changes to TS 6.1.2 a., it is not clear when the Reactor Health Physicist must be present at the reactor. For example, is the Reactor Health Physicist present when fuel movement occurs? Please clarify. You state that the person on call should be able to respond to the facility within approximately one hour.

What is the upper limit to this response?

10.- TS 6.2.3. This TS refers to reactor operations. Please propose wording that reflects the permanent shutdown status of the facility.
