50-293 Response to Request for Additional

_Iplormation Concerning Containment AP.osphere Dilution (CAD) System

Reference:

Telepnone conference conducted on October 15, 1981, between Mr. Mark Williams, Mr. Richard Kendall and Mr. Lawrence Ruth of NRC, and Mr. Robert Tracy, Mr. John Coughlin and Mr. P.M. Kahler of Boston Edison.

Dear Sir:

In the referenced telephone conversation, it was indicated that addi-tional information would serve to clari'y certain aspects of Boston AOOg Edison's previous submittal concarning the CAD system of Pilgrim p 5 Station.

We believe the accompanying attachments will satisfy that request.

Should you have need of any further information regarding this issue, please contact us.

Very truly yours, A.f

SYMPTOMS A.

Drywell pressure 30 psi and increasing.

(?r' B.

Hydrogen concentration greater than 2%.

II.

AUTOMATIC ACTION Reactor vessel low, low water level trip seals in an isolation signal and there is no " override" for this signal.

NOTE: There is no isolation logic associated with the containment purge and vent valves controlled from the PAM panels 0-170 and C-171.

III. 'IMfEDIATE OPERATOR RESPONSE - NITROGEN INERTED PRIMARY CONTAINMENT A.

Assure that the primary containment and secondary containment are properly isolated and that the Standby Cas Treatment System is in service.

B.

Isolate city water to SBGTS spary' system by securing bleek valve in makeup demin area to prevent inadvertent spray of the charcoal.

C.

Place the H Analyzers in service and determine hydrogen concentration 2

par procedure 7.4.19.

See P&ID M-239.

D.

Order nitrogen truck from any vendor on Attachment "A".

E.

When the H, concentration approaches 2%, but within 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> after an accident, 5 pen the following N make-up valves to add nitrogan to the

(

containment. See P&ID M-227. y Nitrogen may come from non-seismic nitrogen tank if available or from truck nitrogen.

NOTE: If nitrogen is not available, service air may be used.

Keep inlet pressure between 65-70 psig to assure that at least 30 scfm of nitrogen is entering both drywell and torus.

SV-5085 SV-5087 SV-5086 SV-5088 F.

Prevent drywell and torus pressures from dropping below 22 psig 'by nitrogen (or service air) addition.

~

G.

Monitor Hydrogen concentration and maintain below 4% by continued addition of nitrogen (or service air) up to a maximum pressure of 28 psig.

H.

Maintain drywell and torus pressures between 22 to 28 psig by nitrogen additioner by venting through vent solenoid valves:
