i ENCLOSURE OYSTER CREEK NUCLEAR POWER PLANT REQUEST FOR ADDITIONAL INFORMATION ON SEP TOPIC III-4.C III-4.C.
Internally Generated Missiles (Inside Containment)
The analysis of internally generated missiles (inside containment) presented in the FDSAR is incomplete. The intent of the following requests is to obtain existing information and analyses.
It may be possible to alleviate some of the concerns with a minimum of additional effort (e.g., detennination of limiting equipment sizes below which there is not enough energy to generate a credible missile).
In such cases, we would like to have this information to be included for our SER; however, these requests do not require you to perform additional analyses.
Provide the following information:
~
1.
Piping layout of the following systems inside containment showing their relative positions from one another and the distance from potential missile sources such as rotating and pressurized equipment inside containment.
a.
Core Spray System b.
Containment Spray System c.
Main Steam Lines and Safety Valves d.
Emergency Condenser System.
2.
The Oyster Creek FDSAR only addresses potential sources of missiles from high pressure equipment.
Provide a discussion of how gravity missiles and secondary missiles are considered in the selection of potential missile sources. A concern exists that heavy equipment which may not be supported adequately may degrade systems identified above.
3.
Identify tanks and cylinders inside containment which may contain compressed gases such as air, oxygen, chlorine, nitrogen, propane, and hydrogen.
If they are present, confirm that they will not become potential missile sources defeating the safety function of the systems identified above.
