9. DISCUSSION, FINDINGS, AND CONCLUSIONS:

Discussion:

Issue "a" The first concern questions the durability.of:the soft (rock wool).

piping' insulation installed at WBNP because of its: alleged'

~

j susceptibility to damage from abuse'and long-term deterioration.

when exposed to vibration. Based on discussion with'the insulation-contractor, the term "SOF" (as quoted on the K-form) does not..

identify any type or brand name-of insulatio'n used at WBN.

Therefore, it is interpreted to mean " Soft."

Rock wool is one of several mineral substances used in t' he' manuf acture of the fibrous type of mass. insulation. " Mineral-Fiber" is the ASTM Standard generic term'for ~ insulation' material'.

composed principally of fibers manufactured from molten mineral substances such as rock, slag, or; glass, with or.without.. binders.

The TVA Insulation Design Guide. (App. A, 5.a)iprovides general and specific requirementsp standards,L and: application' guidelines for.

various types of insulation to be used in nuclear power plants 1 ,

including all metal reflective types' for piping'and equipment; inside containment and massstypes for other piping, equipment"an'd:

ducts. The TVA insulation. specificati.ons-( App. A,15.dLand 5.'e) .,

At SQN plant the majority of installed insulation is m.olded calcium l silicate. However, at SON (and WBN) mineral fiber insulation has j been applied to some piping outside of containment only (excluding '

the mineral fiber block used in the main piping containment ,

penetrations). Typically mineral fiber insulation is installed on j heat traced piping containing borated water, Essential Raw Cooling 1 Water (ERCW) system piping, Raw Cooling Water (RCW) system piping, ,

and some exposed drainage piping. Two forms of mineral fiber _

insulation have been used at SON: i

a. Felted mineral fiber flexible blanket type manufactured from 4 resilient refractory fibers, bonded with organic resin and supplied as a one piece, single layer, wrap-around pipe covering.

b. Rigid preformed mineral fiber type, manuf actured from refractory fibers and with an organic resin binder molded into hollow cylinders, supplied in sections or segments suitable for single or multiple layer pipe covering. 1 i

Both forms of mineral fiber insulation are applied to straight pipe with metal wire or bands and covered with an .016-inch thick aluminumjacket. .

These mineral fiber insulation forms can be characterized as soft Decause of their relatively low compressive strength compared to certain other types of comonly used pipe insulation such as molded calcium silicate. ASTM Standard C165, " Standard Method for .

Measuring Compressive Properties of Thermal Insulation" provides procedures for measuring thermal insulation mechanical behavior under compressive load.

Another of the several mechanical properties which needs to be considered in the selection of insulating material is hardness.

Hardness is defineo as that property which measures a material's ability to resist penetration. It affects ease of application and' is determined by ASTM Standard C569, " Standard Test Method for Indentation Hardness of Preformed Thermal Insulators." The resilience of the wrap-around blanket type is desirable in some piping applications covering small obstructions such as heat-tracing.

Insulations of all types commonly applied to piping are susceptible to some degree of damage if not handled carefully during installation and protected from abuse after installation.- Mineral fiber type piping insulation has been widely used in industrial and' power plant applications and has provided many years of 0082D 12/04/86'

During installation, a reasonable amount of' waste from. abusive'. =

' PAGE 8 0F 11 l Findings:

1 a.1 . Commercially available mineral fiber type piping insulation l has appropriate and economic applications in the SON plant. i j

a.2 The general serviceability of mineral fiber piping insulations is satisfactory when installed and maintained j with reasonable care.

a.3 At SON mineral fiber piping insulations exposed to the-vibration created by fluid flow.in the insulated pipes during i normal operation will not experience a significant loss of j thermal performance over the long term when installed and j maintained in accordance with the manuf acturer's instructions.

b.1 Regulatory Guide 1.36 requirements were recognized by TVA and l all TVA nuclear plants were appropriately instructed'in 1975 '

by Division of Power Production' procedure DPM No. N75M9.

b.2 TVA SON Plant Standard Practice 50M35 (01/18/83) transcribed the Regulatory Guide 1.36 requirements from DPM No. N75M9 and i was incorporated by reference into SQN Plant Procurement i Procedure SOA 45, which governed the purchase of replacement j insulation at the time of the NSRS investigation but did not require quality certification documentation.

Subsequent to the NSRS investigation, the SQN plant staff i I b.3 completed a program of testing nonmetallic insulation i installed and in Power Stores storage areas which verified and documented compliance with Regulatory Guide l.36 req uirement s.

b.4 The SQN plant staff revised procedure SQM35 to incorporate NSRS report recommendations for documenting compliance with ,

Regulatory Guide 1.36 requirements for new nonmetallic ,

insulation purchases at SON.

Conclusion:

a. The concern is not valid for the mineral fiber types of ~

piping insulation installed at SQN.

i- REVISION NUMBER: 1 j PAGE 9 0F 11

b. The concern was valid for nonmetallic insulation at the time it was raised to the NSRS since the SQN plant could not  ;

document compliance with Regulatory Guide 1.36 requirements.

However, subsequent SQN plant actions to revise the  !

insulation procurement procedure and-maintain appropriate i chemical test documentation now assure and demonstrate the 1 acceptable quality of nonmetallic insulation installed on 1 austenitic stainless steel in safety-related systems. Thus- l the perceived problem identified by the concern is resolved. j i
