WM FOR REFLECTIVE INSUIATION 1.0 SCOPE This Specification covers the design, fabricat, ion, shipment, and installation of thermal reflective-type insulation on piping and equipment inside the reactor containment building, all as indicated on the contract drawings and as described in the.
3 specification.
2.0 GENERAL 2.1 Work to be Provided Contractor shall furnish and install all thermal reflective-type insulation for piping and equipment described herein and pro-vide all work required for proper installation.
(
At the Reacter Building penetrations, insulation shall be provided and installed for the wall sleeve projecting on the-inside of containment and the flued fitting joining the wall sleeve to the process piping for the piping systems listed in paragraph 3.4.
All of the'following insulat'ed surfaces shall have removable insulation that will allow for the removal and replacement of the insulated surface without disturbing adjoining insulation:
all equipment (except the pressurizer and steam generators)
Grayloc flanges 5

.2 American Society for Testing and Materials
.3 American National Standards.. Institute
.4 American Welding Society
.5 Federal State and Local Bodies
.6 International Conference of Building Officials (Uniform Building Code) 2.4 Type of Insulation The insulation provided shall be the reflective-type and fabricated entirely of austenitic stainless steel.
2.5 General Desian (33
.1 Insulation shall have a design life of 40 years.
.2 The insulation shall form a system comprised of prefabricated units engineered as integrated assemblies to fit the surfaces to be insulated with due allowance for thermal expansion, contraction, equipment deflection, and other contingencies.
3
.3 Insulation, where required, shall be easily removed for equipment inspection and replaced with no damage to the insulation.
Removable sections shall be small enough to be handled by one man.
1e

insulating or surface characteristics.
.7 Insulation shall be a good fit to minimize air leakage losses.
Panels and segments of units shall have overlapped edges to ensure minimum air leakage losses.
The insulation shall be designed to prevent internal air circulation and chimney effects.
.8 The exterior sheet need not be water tight, but it shall totally enclose the insulation; it shall be drip-proof and shall retain the insulation in position preventing compaction and separation resulting from thermal expansion and contraction of the piping and equipment.
.9 Insulation shall be designed to permit free drainage of any moisture from inside the insulation.
