Attachment SLNRC 82-014 Page Comment Chapter 1 The SER frequently refers to Callaway Unit 2. An SER supplement should state that Unit 2 has been cancelled.

3-17 In Section 3.8.1 the SNUPPS FSAR should be referenced instead of the PSAR.

4-6 In the last paragraph, second line, the "21)" should be cl arified.

5-7 A more accurate statement for item (2) is the following:

"The leakage to the primary reactor containment from unidentified sources is collected and the flowrate is monitored. The monitoring system is capable of detecting a 1 gpm leak within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />."

6-5 In the penultimate paragraph, a statement should be:

"A similar shield design has been incorporated into the reactor cavities of Calvert Cliffs 1 and 2."

7-15 Section 7.3.1.9 should read: "

. .. air provided to the main control room, or of radioactivity in the containment atmosphere or purge gas, and automatically terminates..."

7-15 Section 7.3.1.10, last sentence should read: "

. . . l ow pressure signals coincident with motor-driven AFP automatic' start, the water supply..."

9-12 Seventh paragraph, first line should refer to component cooling water system instead of " emergency service water system."

9-20 First paragraph, last sentence should be replaced by: " Control building air and a portion of the l

recirculating control room air is passed through particulate and charcoal filters, pressurizing the control room to 1/4 - in (w.g.) and preventing unprocessed containments from entering the control room. A second set of charcoal and HEPA filters are provided for pressurization of the control building."

, 9-22 First paragraph, the lines "the safety-related l

protions of the system.... missile-protected enclosure."

( are printed twice.

9-25 First sentence under Diesel Generator Building Ventilation System should read: " ... consists of two independent subsystems, one for each diesel generator room."

I l . - . -

. . Attachmznt SLNRC 82- 014 Page Comment 9-27 First paragraph under Water Supply System, 3rd sentence should read "... electric-fire pump separated

. . . diesel pumps." Also, the reference to NFPA should be National Fire Protection Association.

Third paragraph should read: "

. . . management supervision program with strict key control..."

Fifth paragraph should read: " ... systems is 2300 gpm and, coupled with 1000 gpm for hose streams, creates a total water damand of 3300 gpm at the residual pressure of 80 psig at the yard loop - power block interface."

9-28 First sentence should read: " ... water supply headers except for the diesel rooms which are fed from the yard loop system."

Under " Automatic Water Spray Systems" should read:

Main Transformers, Station Service Transformers, ESF-Transformers _, St'artup Transformer.

9-32 Third paragraph, first sentence should read:

...which continue to the west wall in the control room and interf ace at the wall with vertical wall trays in vertical chases."

10-15 First paragraph, ninth sentence should read: "Th e AFS discharge valves are both motor-operated and air-operated and normally open. The air-operated valves f ail open. . ."

11-2 Line 36, the errata in SER Supplement #1 does not make the entry clear.

12-4 Last paragraph under 12.3.1, second line " comments" should be " components". Also the last sentence concerning field-run piping should be deleted since there is ne field-run piping that contains potentially radioactive material.

12-5 First paragraph, last sentence should read: "

... design uses water bags to reduce..."

12-6 Second paragraph, fourth sentence should read: ..

" ... allows detection of 10 maximum permissible concentration-hours or less in air. .."

Attachment SLNRC 82 014 Page Comment 22-16, 17 Last paragraph should read: "... redundant level transmitters connected to the AFW source switchover system. The transmitters provide level indication and alarms via the BOP computer system. The CST level is also monitored by Class lE pressure transmitters connected to the sucticn lines for each AFP. These transmitters provide low level alarms via the annunciator system. The applicant stated. . .."

22-17 Last paragraph under (3), second line,-delete the word

" redundant."
