MEMORANDUM T0:

K. Steven West, Chief Special Project Section, Plant Systems Branch Division of Systems Safety and Analysis FROM:

Richard C. Paul, Senior Investigator Office of Investigation Field Office Region III

SUBJECT:

TECHNICAL INFORMATION REGARDING DOW CORNING INVESTIGATION (OI CASE NO. 3-93-028R)

On August 18, 1994, J. Lance Simms of Brand Fire Protection was interviewed concerning the change of formulation to the Dow Corning 3-6548 Silicone RTV l

Foam used throughout the nuclear industry in fire penetration seals.

In i

pages 40-41 of his transcribed interview (attached), Simms discussed fire penetration seal systems installed in nuclear facilities not qualified per ASTM E119 acceptance criteria.

t u

Additionally, Simms provided three of the five qualification tests conducted by Dow Corning qualifying their change of formulation to the 3-6548 product.

In Test 1,'two of the installations failed the hose stream test, and Test 2 l

and Test 3 had. temperatures which exceeded 250=F + ambient.

I have attached these tests and the Dow Corning memorandums regarding the modified formulation for your technical review and any action you deem necessary.

It is anticipated that we will be able to forward the two additional Dow Corning tests supporting the formulation change when we obtain the materials from the Dow Corning interviews.

During December,1993, the Supply Systsen hitiased an investigadon of an employee annaarn related to fhe yrler' penetration semis. hfbnnation couected durhg the initial stages of the investigation led to an

% completion of a prana y analysis of the ses1 program, the seals were conservadvely declared

. that sufncient daa===tados had not been assembled to dernonstrate the ^

quaHhtW of the minalnder of the seals.

. 'I1s'tann a"N means "quah6ed by tests that are compamble to tests used to rats the barriers"

(Appendix R. Section IE.hQ and. that "i

.ani seal design' conf,-e and deelga ars

, conshearit witii th6se validated by initial qualification tests" (NRC Informadoo Notics

). The design paameters are those instures which the seal' amst have to pewide the seguired level of the resishmoe.

Dudng the evaluation, it was determined that certain penetration ses! designs do not appear to have q"*""

^'s test documentation. This was determined by conducting a review of penetradon details, reviewing seal design and installation informasonievatuadng insonnation in the seat. dambase, and erffying m-bunt'aonffsmadens in de said. ne sview ardesign :==:-. such as seal depth, sleeving materini, bio.i ot stmetont support, and sparation bet =n i ets wa in. supply system id g -*iaa ther g-uu.% otsome seals.

On Fehniary 15,1994, at apprmi=analy 1330 hourr, this event was nported to the NRC by tel 1

k3eported in, apoordenac with 10CFR50.73(sX2)(liXB) and 50.73(qX2XvXA) because $4 failu j

Wspoond soot cause was that wg'-J. procedures, and drawings were inadequese to provide the 4

lsenect a@uilt seal conggurations. However, no verification was made to ensure that the

&awings which were used to develop the database. Inmarladan and inspection procedures'did

.. liontain adficient acceptanos crheria to' ensure that the seals complied with the critical design i

t.

A.concributing onuse was that daselanalas in the sent pro $ ram and the d=uhana identified by the probiern serAution process were not adequately corrected.

.e Another contributing cause was that the divisiots of reW9 ties for the different aspects of the seal program and Wa=* communication between the'differset on-site Supply System organizations led to inadaduano implemaae f the seal pecssam.
