text: WASHINGTON (AP) — As a crucial second sign-up season gears up, the Obama administration said Sunday that HealthCare.gov is stable and working well, a far cry from last year's frozen computer screens and frustrated customers.

   Health and Human Services Secretary Sylvia M. Burwell said she expects "strong and healthy growth" for 2015. About 7 million people are signed up, and Burwell expects to grow that by 2 million more or so. 
   
   The Congressional Budget Office has projected a total of 13 million enrolled for 2015, and some see the administration as trying to lower expectations. 
   
   Burwell told NBC's "Meet the Press" that 100,000 people had submitted new applications this weekend via the federal website serving 37 states. That's a big difference from last year, when only a handful of customers managed to enroll on the first day. 
   
   Burwell also said that a half-million people who already have coverage through the program were able to log into their accounts this time. 
   
   There were reports Saturday that returning customers had problems, but some of that may have been confusion trying to remember user names and passwords. 
   
   Administration spokesman Aaron Albright said Sunday he had not seen any indication of problems. 
   
   Burwell said call centers have taken 100,000 calls, another indication of consumer interest. 
   
   President Barack Obama noted the improvements. "HealthCare.gov works really well now," he said. 
   
   HealthCare.gov is an online marketplace that offers subsidized private coverage to people who don't have health insurance on the job. Because of political opposition and technical issues, the federal government is running the health insurance exchange in most states. 
   
   Thirteen states and Washington, D.C., are running their own markets. Washington state had problems Saturday with its exchange, which was generating inaccurate subsidy calculations. 
   
   Premiums, on average, appear to be stable this year. But experts say overall national numbers can mask big changes from state to state, and sometimes even within parts of a state. In particular, customers who already got covered this year are being advised to shop around to avoid significant cost increases. 
   
   With Congress fully under Republican control, the administration cannot afford another website meltdown.

   Secretary of Health and Human Services Sylvia Mathews Burwell said on Sunday 100,000 people submitted new applications for Obamacare in the first days of the second open enrollment period. 
   
   Speaking on NBC’s “Meet the Press,” Burwell offered an update to the numbers provided Saturday when she said 23,000 applied in the first eight hours of the new open enrollment period.

   In addition to new applicants, 500,000 customers were able to log on to HealthCare.gov, and 1 million people have gone “window shopping” to compare insurance plans and prices over the past week. 
   
   The numbers offer a stark contrast to the first enrollment period a year ago when HealthCare.gov launched with severe technical problems that prevented people from applying.

target: – After last year's dismal debut HealthCare.gov is feeling much better now, and is busily connecting Americans with health care plans as the second sign-up period opened yesterday, Health and Human Services Secretary Sylvia Burwell said today. The site took in 100,000 new applications in its first 24 hours, reports Politico, saw 500,000 log in to their accounts, and 1 million more went "window-shopping" for plans. Call centers took 100,000 calls. Burwell said she expects "strong and healthy growth" this year—about another 2 million people to add to the 7 million already signed up, per the AP. A White House spokesman said today there was no indication of problems. "HealthCare.gov works really well now," said President Obama.
