Defending champion Ana Ivanovic also overpowered Tamarine Tanasugarn of Thailand 6-1, 6-2.
The eighth-seeded Serb struggled early in her opening match, but she looked to be back to her best on centre court, breaking the 32-year-old Tanasugarn twice in the first set and three times in the second.
In the men's round, Scotland's Andy Murray came from 5-1 down in the third set to advance to the third round, beating Italy's Potito Starace.
Nadal, who is trying to become the first player to win five straight French Open titles, stretched his French Open record to 30-0 by beating Teimuraz Gabashvili of Russia 6-1, 6-4, 6-2.
The top-seeded Spaniard has never lost at Roland Garros, and his 30th straight win on the tournament's red clay gives him the record for most consecutive wins.
The top-seeded Safina took a 5-0 lead to open the match, stretching her streak to 17 straight games after winning 6-0, 6-0 in the first round.
"Pretty good start for the tournament," said Safina, who lost in the Australian Open final and was the runner-up at Roland Garros last year.
"I just played a good game today, good enough to win.''
Diatchenko, an 18-year-old Russian qualifier ranked 153rd, broke Safina once in the second set but failed to convert her only other chance in the first.
"I felt so bad because I didn't play my best game today," Diatchenko said.
"She's in good form. Every ball she put close to the line."
On the men's side, third-seeded Andy Murray survived a brief scare before beating Potito Starace of Italy 6-3, 2-6, 7-5, 6-4.
The Briton was trailing 5-2 in the third set, but he broke Starace three straight times to win.
Murray also reached the third round at Roland Garros last year but lost to Nicolas Almagro in four sets.
In his only other appearance at the French Open in 2006, he lost in the first round.

Twelfth seed Fernando Gonzalez of Chile also advanced, but French veteran
Fabrice Santoro played his last match at Roland Garros.
Santoro, who has made a record 67 Grand Slam appearances, lost in the first round of this year's French Open - his record-tying 20th - to Christophe Rochus of Belgium 6-3, 6-1, 3-6, 6-4.
"Twenty years. That counts for something in a lifetime," Santoro said.
"It has been a long road, a fantastic career. I had a lot of fun and learned a lot."
Santoro and Rochus started their match on Tuesday, but the game was suspended by darkness with the Belgian leading 5-3 in the fourth set.
The pair came back out onto the court after Safina's win and played only eight minutes.
"I'm saying to myself that the story is over, that a page is being turned,'' Santoro said.
"I will no longer be on court next year. But I think that it is time to go.''
Maria Sharapova struggled again in her Grand Slam tournament comeback needing three sets and a few extra games to reach the third round with a 6-2, 1-6, 8-6 victory over 11th-seeded Nadia Petrova.
No. 7 Gilles Simon of France, No. 8 Fernando Verdasco of Spain, No. 12 Fernando Gonzalez of Chile and No. 13 Marin Cilic of Croatia also advanced.
