[o j 3 ; t is the access door from the #2 Emergency Core Cooling System Pump Room 115 to the l

[o}4l l Miscellaneous Waste Monitor Tank Room 114. It is part of the negative pressure boun- !

[ojsj ldary for the Emergency Ventilation System (EVS) and when open would reduce the effec- l l o 16 ] ltiveness of the system. This was an entry into the action statement of Technical Spe-l

[Ol7l {cification 3.6.5.3 which requires this door be closed in Modes 1, 2, 3, and 4. There l

o is lwas no danger. The door could have been closed had the door been needed.  !
