SUBJECT: SALEM NUCLEAR GENERATING STATION, UNITS 1 AND 2- CLOSEOUT OF 

GENERIC LETTER 2004-02, "POTENTIAL IMPACT OF DEBRIS BLOCKAGE 

ON EMERGENCY RECIRCULATION DURING DESIGN BASIS ACCIDENTS AT 

PRESSURIZED-WATER REACTORS" (TAC NOS. MC4712 AND MC4713) 

Dear Mr. Joyce: 

The U.S. Nuclear Regulatory Commission (NRC) issued Generic Letter (GL) 2004-02, "Potential 

Impact of Debris Blockage on Emergency Recirculation During Design Basis Accidents at 

Pressurized-Water Reactors" (Agencywide Documents Access and Management System 

(ADAMS) Accession No. ML042360586) dated September 13, 2004, requesting that licensees 

address the issues raised by Generic Safety Issue 191, "Assessment of Debris Accumulation on 

Pressurized Water Reactor Sump Performance." 

The stated purpose of GL 2004-02 was focused on demonstrating compliance with Title 10 of 

the Code of Federal Regulations (1 0 CFR) Part 50, Section 50.46, "Acceptance criteria for 

emergency core cooling systems for light-water nuclear power reactors." Specifically, the GL 

requested addressees to perform an evaluation of the emergency core cooling system (ECCS) 

and containment spray system (CSS) recirculation. Additionally, it requested addressees take 

additional action, if necessary, to ensure system function, in light of the potential susceptibility of 

pressurized-water reactor sump screens to block during a design basis accident requiring 

recirculation operation of the ECCS or CSS, and due to the potential for additional adverse 

effects due to debris blockage of flowpaths necessary for ECCS and CSS recirculation and 

containment drainage. 

By letters dated March 4, 2005, September 1, 2005, June 7, 2006, and February 2, 2007 

(ADAMS Accession Nos. ML050740368, ML052510438, ML061640118, and ML070440138, 

respectively), PSEG Nuclear LLC (PSEG), provided responses to GL 2004-02 for the Salem 

Nuclear Generating Station, Units 1 and 2. In order for the NRC staff to complete its review, by 

letter dated February 9, 2006 (ADAMS Accession No. ML0603801 01 ), the NRC issued a 

request for additional information (RAI). 

By letter dated February 29, 2008 (ADAMS Accession No. ML080800469), the licensee 

provided responses to the RAis. The NRC staff reviewed the responses and concluded that 

further additional information was required. By letter dated December 17, 2008 (ADAMS 

Accession No. ML083300079), the NRC issued a second set of RAis.

By letter dated March 31, 2009 (ADAMS Accession No. ML091 000557), the licensee provided 

responses to the second set of RAis. The NRC staff reviewed the responses and concluded 

again that additional information was required. By letter dated February 4, 2010 (ADAMS 

Accession No. ML 1 00220520), the NRC issued a third set of RAis. 

By letters dated April 27, 2012, April 22, 2013, and July 11, 2013 (ADAMS Accession Nos. 

ML 121290536, ML 13114A048, and ML 13192A417, respectively), the licensee responded to the 

third set of RAis. 

The NRC staff performed a thorough review of all PSEG responses and RAI supplements to 

GL 2004-02. The NRC staff conclusions have been documented (ADAMS Accession No. 

ML 14113A221 ). Based on the NRC staff conclusions, the NRC staff finds that PSEG has 

provided adequate information as requested by GL 2004-02. The NRC staff finds the 

information provided demonstrates that debris will not inhibit the ECCS or CSS performance of 

its intended function in accordance with 10 CFR 50.46 to assure adequate long-term core 

cooling following a design-basis accident. Therefore, the NRC staff finds the licensee's 

responses to GL 2004-04 are adequate and considers GL 2004-02 closed for the Salem 

Nuclear Generating Station, Units 1 and 2. No further information or action is requested of the 

licensee.
