l SUPPORTING STATEMENT FOR PROPOSED INTERIM REQUIREMENTS RELATED TO HYDR 0 GEN CONTROL 10 CFR 50 1.

JUSTIFICATION The accident at Three Mile Island, Unit 2 (TMI-2) resulted in a severely damaged or degraded reactor core, a concomitant release of radioactive material to the primary coolant system, and a fuel cladding-watter reaction which resulted in the generation of a large amount of hydrogen. The Nuclear Regulatory Commission has taken numerous actions to correct the design and operational limitations revealed '

by the accident.

Included in these actions are several rulemaking proceedings intended to improve the hydrogen control capability of light-water nuclear power reactors. On October 2,1980, the Nuclear Regulatory Commission published in the Federal Register (45 FR 65466) a notice of proposed rulemaking on " Interim

~.

Requirements Related to Hydrogen Control and Certain Degraded Core Considerations" (Interim Rule).

The notice concerned proposed amendments to 10 CFR Part 50,

" Domestic Licensing of Production and Utilization Facilities," to improve hydro-gen management in light-water reactor facilities and to provide specific design and other requirements to mitigate the consequences of accidents resulting in

~

a degraded reactor core.

On March 23, 1981, the Commission published in the Federal Register (46 FR 18045) a notice of proposed rulemaking on " Licensing Requirements for Pending Construc-tion Permit and Manufacturing License Applications." The notice proposed a set of licensing requirements applicable to construction permit applications that stemmed from lessons learned from the TMI-2 accident.

On May 13,1981, the Commission published in the Federal Register (46 FR 26491) a notice of proposed rulemaking on " Licensing Requirements for Pending Operating License Appl.ications" (0L Rule).

As a follow-up to 'the October 2,1980 notice of proposed rulemaking, the Commission published a notice of final rulemaking on December 2,1981 (46 FR 58484) on

~

hydrogen control requirements related to inerting of. Mark I and II boiling water reactors, hydrogen recombiner capability and high point vents.

The Commission has also been considering the ability of all light-water nuclear power reactors, particularly pressurized light-water reactor facilities with ice condenser! type containments and boiling light-water reactor facilities'with Mark III type containments, to withstand ar accident with the concomitant generation L

of larce at.:iunts of hydrogen, such as the type t.hich occurred at Thrte I;ile Island, Unit 2 (ilil-2).

As a result, three new ar..end.ents to the regulations were proposed for public comment on Dece.ber 23,1981 (46 TR 62231).

The final ar..end. ents would require:

(a) improved hydrogen control systems for boiling m

water reactors with liark 111 containments and pressurized water reactors with ice condenser type containments: (b) that those light-water nuclear poiler reactors not relying upon an inerted atresphere for hydrogen control show that certain important safety systems must be able to function during and following hydrogen burning; and finally (c) analyses to be submitted to justify the-hydrogen control systems selected and to provide assurance that containment structural integrity will be maintained and important safety systems will continue to function following a hydrogen burn, for those plants in (a) and (b) above.

The subject of this supporting statement is the requirement that analyses t hould be submitted under (c) above.

The information contained in the analyses is necessary to permit the NRC staf f to perform an evaluation to detqrmine if the requirements for hydrogen control and safety equipment functioning during a hydrogen burn are met.

Without this information the NRC staff could not evaluate the design of the hydrogen control systems selected or determine whether or not needed safety equipment could indeed function during a hydrogen burn.

~

,DE,S,C,R1PT,1OJ( 0F, TJiE,,1in 0.RJ4.AT10.N CO.L L ECT1,0.N 2.

The requircments to submit analyses for both the hydrogen control system and the demonstration of survibability during a hydrogen burn would apply to liark 111 EWRs and ice condenser PWRs in various states of the licensing process.

Due to the similiarities between plants, it is estimated that six reports will be received from power reactor licensees, on a site basis.

The requirement for submittal of the analyses would be on a one time only basis and would not be repeated except to correct deficiences in the reports.

3.

f_Sll!iATE. OF, C,0MPLI Al(CE. BU,RDE.N The reporting of the design and survivability analyses for the six plants (three Mark III BWRs and three ice condenser PWRs) will require approximately 1,500 hours0.00579 days <br />0.139 hours <br />8.267196e-4 weeks <br />1.9025e-4 months <br /> per plant for a total of 9,000 staff hours.
