OHIO CITIZENS FOR RESPONSIBLE ENERGY SIXTH SET OF INTERROGATORIES TO NRC STAFF Ohio Citizens for Responsible Energy ("0CRE") hereby pro-pounds its sixth set of interrogatories to the NRC Staff, pur-suant to the Licensing Board's Memorandum and Order of July 28, 1981 ( LBP-81-24, 14 NRC 175).
Issue #8 Statement of
Purpose:
The following interrogatories are designed to ascertain the Staff's assessment of the hydrogen control features to be implemented at Perry and the ability of the Perry containment to withstand a hydrogen explosion. ,
6-1. What does the Staff consider to be the equivalent of a TMI-2 accident at Perry? Provide the probability of its o currence and hEhorough description of its consequences, including fuel failure modes, effect on containment in-tegrity, and off-site doses.to the public at 2, 5,10, and 50 miles from PNFP.
6-2. What does the Staff consider to be the worst-case accident Provide the probability in terms of H 2 generation at Perry?

-2 sequences, including fuel failure modes, effect on contain-ment integrity,- and off-site doses to the public at 2, 5, 10, and 50 miles from PNPP.
6-3. Has the Staff (or anyone on its behalf or to its knowledge) performed MARCH code calculations specific to Perry for any accident sequences? If so, produce these analyses.
If Perry-specific calculations have not been performed, produce'all MARCH code analyses performed for Grand Gulf (most useful are graphical presentations of the calculated e.g., pp. C-13 to C-44 of NUREG/CR-parameters versus time, 1659, Volume 4).
6-4. Describe in detail the capabilities and limitations of the MARCH code. Discuss any approximations and assumptions and their bases. Specifically, can the MARCH code account for the effects of steam concentration on hydrogen flam-mability, effects of containment structures or equipment on flame fronts, effectiveness of the hydrogen control system, and effects of deliberate hydrogen ignition on the con-tainment and equipment therein?
6-5. Commissioner Gilinsky has stated that the Mark III.is.a weak. containment that should be required to be stronger.
How could the Perry (47 FR 2300, January 15, 1982).
containment be strengthened? Include a cost estimate of all measures that could strengthen the Perry containment.
~
6-6. SECY-80-107A contains view-graphs presented by General Electric to the NRC which state that containment incrting, hydrogen ignition, recombiners, and purging are all im-Does practical for significant rates of H2 production.
i p .
_3_
the Staff agree? If not, why not?
6-7. The Commission has stated that hydrogen control methods that do not involve burning provide protection for a wider spectrum of accidents than do those that involve burning
- /
- (46 FR 62282, December 23, 1981).
What are the bases for v this statement?
y 6-8. , NUREG/CR-1561 at p. 49 states that spontaneous . hydrogen deflagrations or detonations have occurred in the off-gas systems (handling quantities of H2 due to radiolysis) of of several BWRs (Cooper, Browns Ferry 3, Millstone 1).
(a) What were the magnitudes and consequences of these explosions? .
(b) Did these incidents occur because of the failure or inadequacy of the recombiners?
(c) Did'the recombiners provide the ignition source?
(d) Are these recombiners similar to those to be used at Perry?
l , ,
h- 6-9. What is the status of the proposed rule to 10 CFR Part 50, ,
- " Interim Requirements Related to Hygrogen Control," 47 FR 62281, December 23, 19817 l
l 6-10. What types of hydrogen control systems are available f
for preventing H2 buildup and/or explosion in Mark III containments? Briefly discuss each system, listing the advantages and disadvantages of each. Which system is Ii l
f favored by the Staff? Why?
l 6-11. It is stated in the discussion of the proposed rule l, (46 FR 62282) that there are ongoing programs of research pertaining to hydrogen generation, release, burning, and
control. Please list all such research programs. ,

6-16. At what range of H2 concentrations (volume-%) are glow plug igniters effective in reducing H2 concentrations below flammable limits?
t 6-17. Does the Staff believe that the igniters could pose a Suard to the integrity of the containment and the equipment therein by causing severe detonations?
s 6-18. .Does the Staff'believe that the normal, expected operation of the igniters (controlled ignition) could pose a threat
. o to the integrity of the containment or the equipment
.- therein by causing high temperatures and cyclic pressure

If so, produce the results of this analysis, especially describing any instances in which criteria and guidelines: have.not been met. If this analysis has not been performed, when does the Staff intend to do so?
.!. 6-22. FEAR Section 6.2.5.2.1 states that delaying the start of tie analyzers until 15-60 minutes following the LOCA will avoid exposing the analyzer to severe sample con- ,
ditions. In the Staff's opinion, can severe conditions persist beyond 15-60 minutes after the LOCA? After transient sequences?
6-23.~ In the Staff's opinion, for containment H2 concentrations above 4 vol-%, would the mixers accelerate combustion by providing a uniformly combustible atmosphere in the containment? Why or why not?
6-24. In the Staff's opinion, could the ignition of hydrogen by the glow plugs produce missiles that could damage the
' containment or equipment therein? .
