Request for Additional Information-Application Dated August 5,1992 Combustion Engineering, Inc.
Docket No. 70-36 General References to Table I.4.2.4,' Part B, should 'be clarified--.
throughout the report to indicate which operational limits are used.
Design features used for moderation control should be established in Part 1.
Surveillance for designs used as nuclear criticality safety controls should be further discussed in Part=11, such as Section 8.3.7.6 which discusses access ports-- '
provided on the pipe bridge.to_ allow for periodic-inspection.
Please clarify that the transport vehicle route in -
- Figure ll.8.3-21'will_ not be in contaminated areas.
Specific ELqa Comment I.4-5 In Section 4.2.3 (d), techniques should be established regarding fire fighting training.
I.4-6a Section 4.2.3;(s) should specify the two barriers against criticality.
In Section 4.2.3 {t), the design specifications-for the Kardex unit-and separation criteria should be provided.:
Also, the barriers preventing the ingress'of water should be prescribed.
I I.4-6a(1)
-In Section 4.2.3 (u), the minimum separation distance should be_specified or the distance in Section 4.2.7.-
should be referenced.
Section 4.2.3~(v) should specify the barriers _ preventing the ingress of water. Also, moderation-limits.should be established or " unnecessary moderating media" should be explicitly defined.
- i y.._.
p, hgg Comment I.4-6a(3)
The definition of " loose packed rode should include-the.
limits on rod diameter.
I.4-6a(4)
The text referenced in Note (3) of Table I.4.2.4 should be identified.
I.4-10 The structural integrity requirements mentioned _in Section 4.2.10 should be established.- Design criteria:
used to ensure structural integrity should be:provided in Part I, and the techniques used for the inspection of structural integrity should be described _in Part II.
If.8-11aa(2)
The mass limit of 20 kilograms discussed in Section 8.3.7.1.2 contradicts. the mass limit-of -16 kilograms specified in Table 1.4.2.4;- please clarify..
II.8-llaa(3)
Moderation controls, such as_the open faced hood structure design and design of:the working ~ surfaces to rapidly drain water, should be established in Part I.
II.8-11aa(12)
The adequacy of controls to prevent the. accumulation-of water is not fully supported.
Procedures and f
surveillance requirements should be identified to substantiate the adequacy of the barriers that minimize the. potential sources of water. - The moderation controls ~
should be established in Part I.
II.8-llaa(14)
The design of the cooling section of the oven should be established as a moderation _ control'in Part:I.
II 8-11aa(38)
The design specifications of-the pellet storage locations should be established in Part ~I.
II.8-llaa(44)
Limits on the amount of equivalent water for moderator sources that can be.present in the form of lubricants and plastic should be established in Part I.
II.8-11aa(46)
The safety. factor of three in structural design should be established in Part I.
IL8-Ilaa(51)-
The calculation-and assumptions should be provided to show that:the flow rate from the water line is insufficient to result in a water depth throughout the room greater than the slab 1.imits -in Table I.4.2.4 :
Eagg Coment II.8-Ilaa(58)
The mechanical device employed to ensure the I foot separation distance should be identified.
II.8-llaa(73)
The internal dimension of the prestack box exceeds that specified in Table 1.4.2.4; please identify the control used to maintain the safe slab limit.
The design specifications of the fuel rod storage box matrix should be established in Part I.
II.8-lla.(74&75)
The moderation controls for the rod box storage should be established in Part 1.
II.8-llaa(76)
The separation criteria for the rod box storage should be established in Part I.
II.8-Ilaa(77)
A limit on the polyethylene templates should be established.
II.8-11aa(84)
