Subject:

Byron Station Units 1 and 2 Braidwood Station Units 1 and 2 GDC 51 Compliance Review NRC Docket Nos. 50-454/455 and 50-456/45)

Dear Mr. Denton:

Enclosed for your review is the compliance review against GDC 51 for the reactor containment pressure boundary components of our Braidwood Station.

This information was initially reviewed by NRR and addresses the comments we received from Mr. Joseph Halapatz of the Materials Engineering Branch.

This submittal for our Braidwood Station should resolve Outstanding Item No. 4 (Part A) in the Braidwood SER.

Additinnally enclosed is the similar review for Byron Station.

This information was previously reviewed by NRR and was addressed in the Byron SER Section 6.2.7.

One signed original and fifteen copies of this letter with the compliance reviews are provided for your use.

However, due to the voluminous nature of the attachments to the reviews, the attachments have been directly sent to Ms. Janice A. Stevens.

Very truly yours, E. Douglas Swa Nuclear Licensing Administrator cc:

BRAIDWOOD-STATION GDC 51 COMPLIANCE REVIEW' l.

' The lowest - service metal temperature -(LSMT). is identified as the -limiting temperature which :will be experienced by the

11' iting materials 'of. the
containment pressure boundary when m

they.are providing _ a pressure -boundary during. the performance of the containment 1 function ~.under operating, maintenance test-

~

zing andipostulated, accident' conditions, as sited by GDC-51.-

'The-following environmental' zones contain the containment Lpressure boundary:

A-8,.T-3 and C-6.

The _ pressure retaining

' integrity of 'the containment vessel does not apply during maintenance operations - since the eg'uipment hatch may be open.

. During operation, the LSMT is the same temperature as the fluid

inside the pipe.

During-testing, the pressure boundary may sustairs loads during hydrostatig tests.and the integrated leak rate l test.

The hydrostatic tests are conducted at or above 70 F for. piping which.is. constructed ~of 5/8" thick or more carbon steel.

The integrated leak rate test may be conducted -

at a ~ minimum temperature of '50 F, however, this. pressure is much11ess than; the h'ydrostatic : test pressures encountered.

During postulated accident conditions the LSMT is ' expected to be.above 102 F 'in - all zones.

%.s*

~ Containment pressure boundary materials have been reviewed-

.within the context of General Design Criteria 51.

.The' follow-ing ' components have been identified as having materials which -

' fall under the context' of-this revie'w:

Equipment and Personnel Hatch, penetration sleeves, closure plates and flued heads,

' piping and isolation valves..The analysisLof these components

follows.

The ASME III, 1977 summer' addenda code-rules apply to all components unless specifically noted otherwise and will be referred to as "the Code" hereinafter.

.The lowest. service metal ' temperature. (LSMT) 'is. identified as.

the. llmiting temperature which will be, experienced by - the

limiting materials of the containment pressure boundary when
  • they' are providing a pressure: boundary during the performance
of the containment function under ' operating, maintenance test-

-ing and postulated accident conditions, as sj.ted by GDC-51.

!^

The following environmental zones contain the' containment pressure boundary:

A-8, T-3 and C-6.

The pressure retaining integrity. of the containment vessel does not. apply during a

maintenance operations since the equipment hatch may be open..-

During operation, the' LSMT is the same temperature as the fluid cinside'the pipe.~

During testing, the pressure boundary may sustain loads during hydrostatic ' tests and the integrated leak rate. test.

The hydrostatic tests are conducted at or above J

70.F for piping which-is constructed of 5/8" thick or more Lcarbon' steel.

The integrated leak. rate test may be. conducted

at a. minimum temperature of 50 F, however, this pressure is much 'less than the hydrostatic test pressures encountered.

During postulated accident conditions the LSMT is e'xpected to 1

s M

be above.102)F in all zones.

Containment pressure boundary materials have been reviewed Within=the context of General ~ Design Criteria 51.

The follow-ing. components have been identified as having ' materials which n,
