09/86: . Concern to be considered generic Discussion:

Background:

'l

" Concern BNP-QCP-10.35-18 was initially. raised 06/23/86.on BLN. j Because of.its general nature, the concern was. subsequently l 'i determined to :be generically applicable to WBN, SQN, BLN, and BFN.

l L

.No NSRS' investigations were conducted in response to this concern, ,!

.( and no specific corrective actions have taken place-as a result of- l it. Documentation supporting the statement:"taken out at.SQN and '

)

replaced with other switches" could not be established.-  ;

1 '

!' The CI~is. clear about the fact that he is "not concerned with

l. mercury contamination" yet goes on to express the opinion that '1

" mercury switches'are not' supposed to be used.on nuclear power i plants." This is interesting since." mercury. contamination" was i established as early:as 1968 as the predominant basis.for.its

. exclusion'in' critical areas and systems (App.'A,.5.a). This 1 exclusionwasformalizedasTVAdesignguidance=in1983(App.A, 5.d).

Not only does mercury adversely interact with other metals used in nuclear power plants (stainless steel, aluminum, copper containing  !

alloys, Inconel, etc.), it is also toxic'and should be excluded from closed spaces (e.g., nuclear submarines) in which personnel must work. These exclusions are so well understood and implemented (App. A, 5.d) that the concern seems to be addressing the use of

" mercury switches" from a specific applications standpoint. This evaluation proceeds on that basis.

Instrument Application t

Mercury is the only electrically conductive metal that exists in lf ' liquid form at standard temperature and pressure. In switch L 'h . applications its tendency to provide a clean contact surface on

Jeach change of state.gives it a clear advantage over " dry" type d

contacts that are. prone to pitting and corrosion. Mercury . type .-

switchesfare essentially maintenance free and are frequently used I e ,

" ' extensively where accessibility or'oth'er maintenance hampering q 4  ; problems are' encountered.

$ . Proper application of mercury switches, however, must- also. consider F "' isome:of'its' disadvantages,.one of which is spurious actuation by s

vibration. When mercury contacts are made in " tilt bottle" app 1_ications'(i.e., where the mercury is contained in a glass

~

bottle and makes contact between two fixed electrodes ~as the bottle i . Lis physically " tilted" to position by an outside . force) the tendency:of the meniscus to break and the ease with which the metal  !

~w ill' flow Wakes'the point of. transfer (i.e., contact change of F state).somewhat unpredictable under vibratory conditions. As the bottle approaches.the transfer point the sensitivity to premature

or erroneous transfer from induced vibratory motion increases. For these reasons, the use of mercury switches is best restricted to 7 slow moving processes where vibration-free mounting is possible and S the-switch transfer point is not critical (e.g., large tank.or sump level monitoring). Where the' process has inherent pulsating or

/f vibratory motion (e.g., air compressors, diesel engines,~etc.) or

- the transfer point is critical, especially with a narrow set-reset

= range, such' applications are ill-advised.

As a point of clarification, it should be noted that the above

discussion does not apply to mercury wetted contacts whose transfer point is established.by positive means (i.e., manual transfer,

. electromagnetic coil, etc.) not sensitive to vibration. Also, the ,

l amount of mercury in most mercury wetted contacts is small and in a contained state so that the contamination potential is nil.

For these reasons, TVA Mechanical Design Standard OS-M18.1.2 exempts instruments with " mercury wetted contacts" from the i restrictions imposed on the use of mercury in TVA projects.

Regulatory Guidance

/

The general application of 10CFR50 Appendix A, General Design Criterion.2 stipulates that " components important to safety" must not lose their ability to " perform their safety functions" when subjected to " natural phenomena" including earthquakes. The  !'

  1. possibility of a spurious transfer initiating an action adverse to safety during a seismic event has generally caused nuclear power designers to avoid using mercury switches in safety-related ,

2 applications like the SQN diesel generators. While absolute prohibition may be unnecessary, these limitations, coupled with f r

-[ PAGE 6 0F 16 mercury's contamination potential, has generally discouraged their

use. Documentation internal to TVA has pointed out these  ;

-limitations (App. A, 5.b and c).

)

The application limitations outlined above, as well-as the ever-present contamination-potential, often-incur design control programs that outweigh the advantages. In such instances, it may ,

1 be more effective to exclude the use of mercury entirely. This  !

approach was suggested as early as 1971-(App. A, 5.b) during the

, design phase of SQN. Up to 1983, the time that official design.

. guidance'(App. A, 5.d) was issued on the subject, this approach was ,

apparently so well understood that the general presumption l expressed in the concern (i.e., " Thinks mercury switches are not I supposed to be used in nuclear plants") obtained general acceptance as design guidance in the absence of any documented practice.

However, a universally applied and documented prohibition, as such, l against the use of mercury switches in the nuclear power industry i does not exist. In 1980, an NRC IE Bulletin (App A, 5.h) was ,

issued-on a specific make and model mercury wetted relay, but the ,

issu'e.there was a malfunction not related to the use of mercury.  !

( Verification Program ,

While the foregoing would tend to restrict the use of mercury-switches at SQN, it does not confirm that they have not been used or, if'used, that they were properly applied. To respond to this issue, the evaluation team first identified the instrumentation on systems in the Diesel Generator Building and then physically inspected them to ensure that they did not use mercury.

A review of SQN drawings (App. A, 5.1 through p) showed the following diesel generator support systems to have instruments in the Diesel Generator Building:

Fuel Oil System, System 18 High Pressure Fire Protection System, System 26 CO2 Storage, Fire Protection and Purge Systems, System 39 Diesel Starting Air System, System 82 Lube Oil System, System 82 i The Instrument Tabulation (App. A, 5.q) shows that the instru.nents listed in Appendix B are located on these systems in the Diesel Generator Building.

A physical walkdown of the SQN Diesel Generator Building, augmented by a review of vendor drawings and calibration records, established the manufacturer and model number of each instrument listed in k Appendix B.

05880 - 03/09/87

i TVA' EMPLOYEE CONCERNS REPORT NUMBER: 229.10(B).

SPECIAL PROGRAM REVISION NUMBER: 1 j PAGE'7 0F 16 ,

As noted in Appendix B, some'of the instruments were inaccessible so narreplate identification was not pnssible. In these cases j vendor prints were used to identify make and model. With make and 1 model known, commercial literature was used to establish the. l presence or absence of mercury. No mercury containing switches were found.

~ Findings:

)

Evidence that mercury switches were-installed and then "taken out at SQN and replaced with other switches" could not be found.

Documentation early in the design phase of SQN indicates that such mercury switches were, as a general practice, to be avoided. The present instrumentation installed in the Diesel Generator Building  ;

is in agreement with the TVA Design Standard D5-M18.1.2 which j restricts the use cf switches containing free mercury. Physical j walkdown of the Dienel Generator Building at SQN verified that no  !

mercury containing switches are presently installed.

Conclusions:

The contamination potential and'the limitations of mercury switches

(~ in instrumentation applications are well established. By custom i and precedent this has led to very restrictive use of such devices in nuclear power plants. Present TVA design guidance now clearly documents these restrictions, but common engineering practice has precluded their use prior to such guidance being documented. The absence of mercury switches in the SQN Diesel Generator Building has been confirmed by physical walkdown. The concern is not valid for SQN.

10. CORRECTIVE ACTION:

No corrective action is required.
