3.1.3 Fire Drenka shall he mnde from nn Innulation Blanket and mantic runting, or PPht. Fngineering npproved equnt. nee Section 3.5.
3.2 FlHE P,HEAK CONSTHitCTION (Typical For Inntlation Blanket Material Only) 3.2.1 Fire Breaks shall completely encapsulate the cable tray fer six to eight inchen (nominal Hin. Dimensfor' 3.2.2 If the enble tfny in not completely filled with cables. I Innulntion Blanket. the anme width ne the cable tray shall be inserted over the enhlen in sufficient Inycra to briny, the outer surface of the Innulation Blanket even with the top of the tray sides and completely fill all void apncen.

trnyn. condults and junction / terminal boxes at locations specified per Sunquehanna Fire Protection Review Report Appendix "A".
3.3.2 En osure Fire Barriers shall be made by encasing the cable trays, con u en and junction / terminal boxen in one hour rated barrier nyntem.
}
3.3.3 The purpone of Exponure Fire Barriers in to prevent damage, during n i bour complete engulfment fire, to electrical cables serving one 3
i division of equipment required for safe shutdown of the plant when redundant safe shutdown divisions occupy the same fire area.

3.4 EXPOSURE FIRE BARRIER CONSTRUCTION (Typical For Insulation Blanket Haterial only) 3.4.1 Exposure Fire Barriers shall completely encapsulate the indicated cable tray or conduit for the entire length specified.
3.4.2 If the cabic tray is not covered and is not completely filled with cablen, insulation Blanket, the same width as the cable tray, shall ;
be innerted over the cables in sufficient layers to bring the outer :
surface of the Insulation Blanket even with the top of the tray sides. 1 3.4.3 The firne (interior) 1.ayer o f ti - Insulation Blanket shall vrap i
completely around the perimeter of the cable tray with the ends of the j blanket overlapping a minimum of 3 inches. Adjacent blankets shall be pinced tightly together so us to prevent any gaps in the butt joints between blankets.

inches from butt joints.
1.4.4 The second (exterior) layer of Insulation Blanket shall vrap completely around the perimeter of the ircerior layer and must also have a j minimum 3 inch overlap. The overlap of the exterior layer shall be offnet l from the overlap of the interior Inyer but still remain on the top of the l tray. The exterior laycr blankets shall be installed such that the butt jointa between adjnecnt exterior blankets are offset at leant 12 inche*
f rom the butt joints between interior blankets. :
3.4.5 The exterior blankets shall be secured in place by stainlesa
, necc1 straps installed not more than 14 inches apart and not lenn than 4 inches from exterior butt joints. The tensioning of the straps shall be
. nufficient to hold the binrket snugly in place without causing any nufficient cutting of or damage to, the blanket material.
3.4.6 A protective outer wrap of Aluminized Zet'ex is to be secured independently of the Kaowool blanket with Polyken 237 tape. This outer wrap shall be installed after the stainless steel straps. The "setes" shall have a minimum 3 inch overlap. The overlaps in the outer wrap shall be offset from the overlaps in the previous layer but still remain on top of the tray. A single layer of Polyken 237 tape will be made over all joints. (The above is typical for all barriers constructed with Insulation Blanket Material Kaowool.)
l 3.4.7 Where adjoining cable tray or conduit or troy support members attached to, or come into contact with, the tray to be protected the attaching or contacting member shall also be wrapped with two layers of Insulation Blanket as necessary to ensure complete coverage of the protected tray. No gaps or openings shall be allowed.

J j 3.4.11 At locations where the protected tray or conduit penetrates a 1 4
fire barrier in a ceiling, floor or wall, both the interior end exterior I i layers of Insulation Blanket shall be cut and installed such that the
